Emerging roles of the chromatin remodeler MORC2 in cancer metabolism.

Cancer is characterized by metabolic reprogramming in cancer cells, which is crucial for tumorigenesis. The highly deregulated chromatin remodeler MORC2 contributes to cell proliferation, invasion, migration, DNA repair, and chemoresistance. MORC2 also plays a key role in metabolic reprogramming, including lipogenesis, glucose, and glutamine metabolism. A recent study showed that MORC2-regulated glucose metabolism affects the expression of E-cadherin, a crucial protein in the epithelial-to-mesenchymal transition. This review discusses recent developments in MORC2 regulated cancer cell metabolism and its role in cancer progression.

Prospective randomized study correlating intra-operative urethral mucosal injury with early period after transurethral resection of the prostate stricture urethra: A novel concept.

Objective: To investigate the incidence of urethral stricture during the early period after transurethral resection of the prostate (TURP) and correlate its incidence with intra-operative urethral mucosal injury during TURP. Also to compare the other established risk factors affecting the development of urethral stricture among patients undergoing monopolar or bipolar TURP over a period of 6 months follow-up as the prospective randomized study. Methods: One hundred and fifty men older than 50 years with lower-urinary tract symptoms associated with benign prostatic hyperplasia were randomized to undergo either standard monopolar TURP with glycine as the irrigation fluid or bipolar TURP with normal saline as irrigant. The prostate size, operative time, intra-operative mucosal rupture, catheter time, catheter traction duration, uroflowmetry, and post-operative stricture rate were compared. Results: A total of 150 patients underwent TURP, including 74 patients undergoing monopolar TURP (one patient was excluded as his post-operative histopathological examination report was of adenocarcinoma prostate) and 75 patients undergoing bipolar-TURP, all of which were performed using a 26 Fr sheath resectoscope. The mean International Prostate Symptom Score and maximum urinary flow rate score at post-operative 3 months and 6 months were comparable between the groups. Out of 149 patients, nine patients (6.0%) developed urethral stricture. The severity of the injury (urethral mucosal injury) correlated with the likelihood of developing a subsequent complication (stricture urethra). Patients with stricture had significantly larger prostate volume than patients without stricture (65.0 mL vs. 50.0 mL; p=0.030). Patients with stricture had longer operative time than patients without stricture (55.0 min vs. 40.0 min; p=0.002). In both procedures, formation of post-operative stricture urethra was independently associated with intra-operative mucosal injury. Conclusion: Intra-operative recognition of urethral mucosal injury helps in prediction of stricture urethra formation in early post-operative period.

Crofton weed derived isomers of ageraphorone as potent antifeedant against Plutella xylostella (L.).

Global agricultural production is significantly hampered by insect pests, and the demand for natural pragmatic pesticides with environmental concern remains unfulfilled. Ageratina adenophora (Spreng.) also known as Crofton weed, is an invasive perennial herbaceous plant that is known to possess multiple bioactive compounds. In our study, two isomers of ageraphorone metabolites i.e, 10 Hα-9-oxo-ageraphorone (10HA) and 10 Hß-9-oxo-ageraphorone (10HB), were identified from Crofton weed, exhibiting potent antifeedant and larvicidal activities against Plutella xylostella. For antifeedant activity, the median effective concentration (EC50) values for 10HA and 10HB in the choice method were 2279 mg/L and 3233 mg/L, respectively, and for the no choice method, EC50 values were 1721 mg/L and 2394 mg/L, respectively. For larvicidal activity, lethal concentration (LC50) values for 10HA and 10HB were 2421 mg/L and 4109 mg/L at 48 h and 2101 mg/L and 3550 mg/L at 72 h. Furthermore, both in- vivo and in-vitro studies revealed that the isomers 10HA and 10HB exhibited potent detoxifying enzymes inhibition activity such as carboxylesterase and glutathione S-transferases. Molecular docking and MD simulation analysis provide insight into the possible interaction between isomers of ageraphorone metabolites and Carboxylic Ester Hydrolase protein (Gene: pxCCE016b) of P. xylostella, which led to a finding that CarEH protein plays a significant role in the detoxification of the two compounds in P. xylostella. Finally, our findings show that the primary enzymes undergoing inhibition by isomers of ageraphorone metabolites, causing toxicity in insects, are Carboxylesterase and glutathione S-transferase.

Aptamer and Aptasensor Technology for Diagnosis of Infectious Diseases: A Mini Review.

BACKGROUND: Aptamers are not so new a concept, however, it is scarcely discussed by medical fraternity. Aptamers are potent, new identification molecules set to rope in a new technique in the diagnostic arena. Aptamers have started almost a revolution in diagnostic assays since their discovery in the 90s. (Radu S. Current and previous disease outbreaks around the world, U.S. News & World Report. 2020 Mar 13 [cited 2024 Jun 17]. Available from: https://www.usnews.com/news/best-countries/slideshows/20-pandemic-and-epidemic-diseases-according-to-who) provides an overview of pandemics and epidemics as reported by the WHO. It is interesting to note that several endemic and epidemic diseases viz. Chikungunya, Cholera, Crimean-Congo haemorrhagic fever, Ebola virus disease, Hendra virus infection, Influenza, Lassa fever, Marburg virus disease, Meningitis, MERS-CoV (Middle East Respiratory Syndrome Corona Virus), Monkeypox, Nipah virus infection, Novel coronavirus, Plague, Rift Valley fever, SARS (Severe Acute Respiratory Syndrome), Smallpox, Tularaemia, Yellow fever, and Zika virus disease have been identified by the WHO and are being explored for applicability of aptamer technology in their identification. OBJECTIVES: One of the most important necessities to control epidemic or pandemic diseases is early diagnosis. However, the majority of the diagnostic tests for these diseases are available only in tertiary care centres. The objective of this review is to discuss the potential of aptamer technology to provide undemanding, simple, specific, sensitive, and cost-effective diagnostic assays that are usable in remote and field conditions. CONTENT: Here, we discuss recent advances and approaches in aptamer and aptamer engineering useful in the diagnosis of infectious and non-infectious conditions. This review also discusses a few sensing discoveries which are a gift of advanced engineering and technology using optical and electrochemical aptasensors. It's still a long way to go, and we need to take into account the technological challenges being faced by aptamer-aptasensor technology.

Metal-Free Regioselective Oxa-Michael Approach to Access Spirooxindole-Fused Tetrahydrofuran/Tetrahydropyran through [3 + 2]/ [4 + 2] Spirocyclization of Methyleneindolinones with Haloalcohols.

An efficient one-pot metal-free, base-catalyzed method has been developed for the regioselective [3 + 2]/[4 + 2] annulation reactions of electrophilic methyleneindolinones with haloalcohols to furnish spirooxindole derivatives under mild reaction conditions. This reaction afforded the corresponding products with two contiguous stereocenters including a quaternary center in good to excellent yield (up to 95%) with moderate to good diastereoselectivities (up to 12.5:1 dr) with complete regioselectivity.

Amelioration of experimental autoimmune encephalomyelitis by gemfibrozil in mice via PPARß/δ: implications for multiple sclerosis.

It is important to describe effective and non-toxic therapies for multiple sclerosis (MS), an autoimmune demyelinating disease. Experimental autoimmune encephalomyelitis (EAE) is an immune-mediated inflammatory disease that serves as a model for MS. Earlier we and others have shown that, gemfibrozil, a lipid-lowering drug, exhibits therapeutic efficacy in EAE. However, the underlying mechanism was poorly understood. Although gemfibrozil is a known ligand of peroxisome proliferator-activated receptor α (PPARα), here, we established that oral administration of gemfibrozil preserved the integrity of blood-brain barrier (BBB) and blood-spinal cord barrier (BSB), decreased the infiltration of mononuclear cells into the CNS and inhibited the disease process of EAE in both wild type and PPARα-/- mice. On the other hand, oral gemfibrozil was found ineffective in maintaining the integrity of BBB/BSB, suppressing inflammatory infiltration and reducing the disease process of EAE in mice lacking PPARß (formerly PPARδ), indicating an important role of PPARß/δ, but not PPARα, in gemfibrozil-mediated preservation of BBB/BSB and protection of EAE. Regulatory T cells (Tregs) play a critical role in the disease process of EAE/MS and we also demonstrated that oral gemfibrozil protected Tregs in WT and PPARα-/- EAE mice, but not PPARß-/- EAE mice. Taken together, our findings suggest that gemfibrozil, a known ligand of PPARα, preserves the integrity of BBB/BSB, enriches Tregs, and inhibits the disease process of EAE via PPARß, but not PPARα.

Combined topography-guided photorefractive keratectomy and corneal collagen crosslinking.

PURPOSE: This study aimed to report the long-term results of combined topography-guided photorefractive keratectomy (PRK) and accelerated corneal collagen cross-linking (CXL) for keratoconus using the Zeiss refractive coordinated system. METHODS: A prospective interventional study was conducted in a tertiary eye care hospital in South India. Patients with mild-to-moderate progressive keratoconus and corneal pachymetry greater than 450 µm were included. They underwent customized topography-guided PRK followed by CXL. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and keratometry readings and complications were evaluated at 1, 3, 6, 12, and 24 months postoperatively. RESULTS: Thirty patients (30 eyes) were included in the study. All study parameters showed a statistically significant improvement postoperatively over baseline values. At 24 months, the mean UDVA improved from 0.8 ± 0.180 logarithm of the minimum angle of resolution (logMAR) to 0.38 ± 0.118 logMAR ( P -value <0.001) and CDVA improved from 0.467 ± 0.142 logMAR to 0.227 ± 0.078 logMAR ( P -value <0.001). The mean flat, steep, and maximum keratometry values were significantly reduced by 2.133, 3, and 4.54 diopters, respectively, at the last follow-up examination ( P -value <0.001). CONCLUSION: The combined topography-guided PRK and accelerated CXL procedure seem to be a promising treatment alternative for early keratoconus. This is the first such study on the Zeiss refractive coordinated system. However, further studies with a larger study population and longer follow-up periods are required to draw final conclusions about the benefits of this procedure in keratoconus.

Consequences of medical negligence and litigations on health care providers - A narrative review.

Medical professionals face high stress due to the type of work they do and the prolonged working hours. Frequent burnout results due to the challenging nature of their work. Added to the stress of work, malpractice lawsuits add to their burden. In India, most doctors work in compromised settings with poor infrastructure and manpower but are expected to follow the best practices. In court, they are judged with the Bolam and Bolitho tests being essential considerations. Several tragic incidents have been reported, including depression, anger issues, and even suicide deaths of healthcare professionals (HCPs) after accusations of negligence and subsequent inquiry. Such incidents demonstrate the multitude of challenges an HCP faces in day-to-day practice. It is crucial to find ways to tackle these problems and enhance the capacity of HCP to handle such demanding circumstances. Malpractice litigation can significantly impact the mental health of HCPs. It is common to experience emotional turmoil when faced with a lawsuit. Second victim syndrome (SVS) is a term used to describe a set of symptoms experienced by HCPs who make an error leading to injury to a patient. However, it also happens if he is traumatized by the consequences of violence during healthcare services or a lawsuit or defamation article in newspaper/social media. Following a litigation crisis in their career, many HCPs go through various stages of grief, including shock, denial, anger, bargaining, depression, and acceptance. At times, death by suicide of the HCPs is well known. SVS is known to profoundly affect the personal, family, economic, professional (defensive practice), and social life of HCPs. HCPs should accept the allegations of negligence as an occupational hazard and prepare for the eventual litigation at least once in a lifetime by knowing about the medical laws, HCP's rights, becoming aware of the emotional turmoil of the lawsuit, preparing to cope with the lawsuit, and seeking help from colleagues and indemnity insurance. Frequent training of the HCPs is strongly recommended to know about the changing laws and also to undergo periodic professional competence enhancement to reduce the incidents of errors amounting to medical negligence. Medical and hospital administration should debrief after any incident and conduct internal investigations to identify systemic flaws and prevent future recurrence, resolve issues within their control at their level, and manage media (mainstream and social media) appropriately. If established, a reporting system with online and offline services will ease the internal administrative investigation process and take appropriate, timely actions. During the crisis, HCPs should have adequate and appropriate insurance or indemnity coverage and mental health support systems.

Therapeutic efficacy of cinnamein, a component of balsam of Tolu/Peru, in controlled cortical impact mouse model of TBI.

Traumatic brain injury (TBI) remains a major health concern which causes long-term neurological disability particularly in war veterans, athletes and young adults. In spite of intense clinical and research investigations, there is no effective therapy to cease the pathogenesis of the disease. It is believed that axonal injury during TBI is potentiated by neuroinflammation and demyelination and/or failure to remyelination. This study highlights the use of naturally available cinnamein, also chemically known as benzyl cinnamate, in inhibiting neuroinflammation, promoting remyelination and combating the disease process of controlled cortical impact (CCI)-induced TBI in mice. Oral delivery of cinnamein through gavage brought down the activation of microglia and astrocytes to decrease the expression of inducible nitric oxide synthase (iNOS), glial fibrillary acidic protein (GFAP) and ionized calcium binding adaptor molecule 1 (Iba1) in hippocampus and cortex of TBI mice. Cinnamein treatment also stimulated remyelination in TBI mice as revealed by PLP and A2B5 double-labeling, luxol fast blue (LFB) staining and axonal double-labeling for neurofilament and MBP. Furthermore, oral cinnamein reduced the size of lesion cavity in the brain, improved locomotor functions and restored memory and learning in TBI mice. These results suggest a new neuroprotective property of cinnamein that may be valuable in the treatment of TBI.

Nebulization of low-dose aspirin ameliorates Huntington's pathology in N171-82Q transgenic mice.

Huntington Disease (HD), a devastating hereditary neurodegenerative disorder, is caused by expanded CAG trinucleotide repeats in the huntingtin gene (Htt) on chromosome 4. Currently, there is no effective therapy for HD. Although aspirin, acetylsalicylic acid, is one of the most widely-used analgesics throughout the world, it has some side effects. Even at low doses, oral aspirin can cause gastrointestinal symptoms, such as heartburn, upset stomach, or pain. Therefore, to bypass the direct exposure of aspirin to stomach, here, we described a new mode of use of aspirin and demonstrated that nebulization of low-dose of aspirin (10 µg/mouse/d=0.4 mg/kg body wt/d roughly equivalent to 28 mg/adult human/d) alleviated HD pathology in N171-82Q transgenic mice. Our immunohistochemical and western blot studies showed that daily aspirin nebulization significantly reduced glial activation, inflammation and huntingtin pathology in striatum and cortex of N171-82Q mice. Aspirin nebulization also protected transgenic mice from brain volume shrinkage and improved general motor behaviors. Collectively, these results highlight that nebulization of low-dose aspirin may have therapeutic potential in the treatment of HD.

Discovery of DNL343: A Potent, Selective, and Brain-Penetrant eIF2B Activator Designed for the Treatment of Neurodegenerative Diseases.

Eukaryotic translation initiation factor 2B (eIF2B) is a key component of the integrated stress response (ISR), which regulates protein synthesis and stress granule formation in response to cellular insult. Modulation of the ISR has been proposed as a therapeutic strategy for treatment of neurodegenerative diseases such as vanishing white matter (VWM) disease and amyotrophic lateral sclerosis (ALS) based on its ability to improve cellular homeostasis and prevent neuronal degeneration. Herein, we report the small-molecule discovery campaign that identified potent, selective, and CNS-penetrant eIF2B activators using both structure- and ligand-based drug design. These discovery efforts culminated in the identification of DNL343, which demonstrated a desirable preclinical drug profile, including a long half-life and high oral bioavailability across preclinical species. DNL343 was progressed into clinical studies and is currently undergoing evaluation in late-stage clinical trials for ALS.

Clinical Utility of SARS-CoV-2 Serological Testing and Defining a Correlate of Protection.

Herein, we review established clinical use cases for SARS-CoV-2 antibody measures, which include diagnosis of recent prior infection, isolating high titer convalescent plasma, diagnosing multisystem inflammatory syndrome in children (MIS-C), and booster dosing in the immunosuppressed and other populations. We then address whether an antibody correlate of protection (CoP) for SARS-CoV-2 has been successfully defined with the following considerations: Antibody responses in the immunocompetent, vaccine type, variants, use of binding antibody tests vs. neutralization tests, and endpoint measures. In the transition from the COVID-19 pandemic to endemic, there has been much interest in defining an antibody CoP. Due to the high mutability of respiratory viruses and our current knowledge of SARS-CoV-2 variants defining a CoP for prevention of infection is unrealistic. However, a CoP may be defined for prevention of severe disease requiring hospitalization and/or death. Most SARS-CoV-2 CoP research has focused on neutralization measurements. However, there can be significant differences in neutralization test methods, and disparate responses to new variants depending on format. Furthermore, neutralization assays are often impractical for high throughput applications (e.g., assessing humoral immune response in populations or large cohorts). Nevertheless, CoP studies using neutralization measures are reviewed to determine where there is consensus. Alternatively, binding antibody tests could be used to define a CoP. Binding antibody assays tend to be highly automatable, high throughput, and therefore practical for large population applications. Again, we review studies for consensus on binding antibody responses to vaccines, focusing on standardized results. Binding antibodies directed against the S1 receptor binding domain (S1-RBD) of the viral spike protein can provide a practical, indirect measure of neutralization. Initially, a response for S1-RBD antibodies may be selected that reflects the peak response in immunocompetent populations and may serve as a target for booster dosing in the immunocompromised. From existing studies reporting peak S1-RBD responses in standardized units, an approximate range of 1372-2744 BAU/mL for mRNA and recombinant protein vaccines was extracted that could serve as an initial CoP target. This target would need to be confirmed and potentially adjusted for updated vaccines, and almost certainly for other vaccine formats (i.e., viral vector). Alternatively, a threshold or response could be defined based on outcomes over time (i.e., prevention of severe disease). We also discuss the precedent for clinical measurement of antibodies for vaccine-preventable diseases (e.g., hepatitis B). Lastly, cellular immunity is briefly addressed for its importance in the nature and durability of protection.

Epidemiological and Clinical Presentation of Retinoblastoma among Nepalese Children in 2019.

Suresh B.K. RasailyObjectives Retinoblastoma (RB) is rare but potentially fatal if left untreated. This study aimed to evaluate the epidemiological profile, clinical manifestation, classification, and affordability of RB treatment among Nepalese children in the year 2019. Materials and Method A multicentric, multiethnic hospital-based cross-sectional study after ethical approval from the National Health Research Council was conducted from January 2019 to December 2019 by incorporating ophthalmologists all over the nation. Twenty-seven RB centers were selected. All the RB presented in the RB centers either newly diagnosed or ongoing treatment consented to the study were included and failed to consent for the study, RB survivors were excluded from the study. Data based on demographic profile, clinical manifestation, ethnical and geographical distribution, and treatment received were collected in the customized Google Form. Each case was classified at the time of diagnosis as per the International Classification of Retinoblastoma groups and different treatment modalities offered as per grouping and staging. The affordability of treatment was calculated using a catastrophic approach. Statistical Analysis Data were entered into Microsoft Excel 2010 and analyzed using Statistical Package for Social Sciences version 20. Result A total of 34 RB cases, 21 (61.76%) in ongoing treatment group and 13 (38.2%) in newly diagnosed group presented in the RB centers. Out of total, 32 (64.7%) had unilateral and 12 (35.3%) cases had bilateral involvement. The majority of patients was from Province 1 (35.3%) and belonged to the upper caste (38.2%). Leukocoria was the most common presentation (73.9%) followed by proptosis, red eye, and phthisis bulbi. More than 75% patients presented at advanced group D (54%) and E (21%) and stage 0 (90%). More than 90% of patients received systemic chemotherapy, and 42.6% received transpupillary thermotherapy. The average cost of RB treatment was estimated to be 521% of the nonfood expense of the family which is unaffordable to almost all cases (100%). Conclusion Leukocoria is the most common mode of clinical presentation in both unilateral and bilateral RBs. Early diagnosis and appropriate treatment are key to success for saving life, sight, and eye. However, community awareness programs against RB, active referral networks, and the establishment of chemotherapy centers with trained human resources are needed to reduce loss of life, sight, and eye.

Vaccine value profile for cytomegalovirus.

Cytomegalovirus (CMV) is the most common infectious cause of congenital malformation and a leading cause of developmental disabilities such as sensorineural hearing loss (SNHL), motor and cognitive deficits. The significant disease burden from congenital CMV infection (cCMV) led the US National Institute of Medicine to rank CMV vaccine development as the highest priority. An average of 6.7/1000 live births are affected by cCMV, but the prevalence varies across and within countries. In contrast to other congenital infections such as rubella and toxoplasmosis, the prevalence of cCMV increases with CMV seroprevalence rates in the population. The true global burden of cCMV disease is likely underestimated because most infected infants (85-90 %) have asymptomatic infection and are not identified. However, about 7-11 % of those with asymptomatic infection will develop SNHL throughout early childhood. Although no licensed CMV vaccine exists, several candidate vaccines are in development, including one currently in phase 3 trials. Licensure of one or more vaccine candidates is feasible within the next five years. Various models of CMV vaccine strategies employing different target populations have shown to provide substantial benefit in reducing cCMV. Although CMV can cause end-organ disease with significant morbidity and mortality in immunocompromised individuals, the focus of this vaccine value profile (VVP) is on preventing or reducing the cCMV disease burden. This CMV VVP provides a high-level, comprehensive assessment of the currently available data to inform the potential public health, economic, and societal value of CMV vaccines. The CMV VVP was developed by a working group of subject matter experts from academia, public health groups, policy organizations, and non-profit organizations. All contributors have extensive expertise on various elements of the CMV VVP and have described the state of knowledge and identified the current gaps. The VVP was developed using only existing and publicly available information.

Development of a Simple Electroless Method for Depositing Metallic Pt-Pd Nanoparticles over Wire Gauge Support for Removal of Hydrogen in a Nuclear Reactor.

Electroless noble metal deposition on the conducting substrate is widely used to obtain the desired film or coating on the substrate of interest. Wire-gauge-based Pt/Pd/Pt-Pd (individually, sequentially, and simultaneously deposited) catalysts have been developed using formaldehyde and sodium formate as reducing agents. Various surface pretreatment methods like SnCl2 + PdCl2 seeding, oxalic acid etching, and HCl activation (etching) have been employed to obtain the desired noble metal coating. Minimum time duration was observed for simultaneously deposited catalysts using formaldehyde as a reducing agent. Prepared catalysts were characterized for noble metal deposition, coating kinetics, surface morphology, and binding energy. The catalyst was found to be active for H2 and O2 recombination reactions for hydrogen mitigation applications in nuclear reactors.

Microrchidia 2/histone deacetylase 1 complex regulates E-cadherin gene expression and function.

Although Microrchidia 2 (MORC2) is widely overexpressed in human malignancies and linked to cancer cell proliferation, metabolism, and metastasis, the mechanism of action of MORC2 in cancer cell migration and invasion is yet undeciphered. Here, we identified for the first time that MORC2, a chromatin remodeler, regulates E-cadherin expression and, subsequently regulates breast cancer cell migration and invasion. We observed a negative correlation between the expression levels of MORC2 and E-cadherin in breast cancer. Furthermore, the overexpression of MORC2 resulted in decreased expression levels of E-cadherin. In addition, co-immunoprecipitation and chromatin immunoprecipitation assays revealed that MORC2 interacts with HDAC1 and gets recruited onto the E-cadherin promoter to inhibit its transcription, thereby suppress its expression. Consequently, knockdown of HDAC1 in MORC2-overexpressing cells led to reduced cancer cell migration and invasion. Interestingly, we noticed that MORC2-regulated glucose metabolism via c-Myc, and LDHA, also modulates the expression of E-cadherin. Collectively, these results demonstrate for the first time a mechanistic role for MORC2 as an upstream regulator of E-cadherin expression and its associated functions in breast cancer.

Novel Insights into the Role of Chromatin Remodeler MORC2 in Cancer.

A newly discovered chromatin remodeler, MORC2, is a Microrchidia (MORC) family member. MORC2 acts as a chromatin remodeler by binding to the DNA and changing chromatin conformation using its ATPase domain. MORC2 is highly expressed in a variety of human cancers. It controls diverse signaling pathways essential for cancer development through its target genes and interacting partners. MORC2 promotes cancer cells' growth, invasion, and migration by regulating the expression of genes involved in these processes. MORC2 is localized primarily in the nucleus and is also found in the cytoplasm. In the cytoplasm, MORC2 interacts with adenosine triphosphate (ATP)-citrate lyase (ACLY) to promote lipogenesis and cholesterogenesis in cancer. In the nucleus, MORC2 interacts with the transcription factor c-Myc to control the transcription of genes involved in glucose metabolism to drive cancer cell migration and invasion. Furthermore, MORC2 recruits on to the promoters of tumor suppressor genes to repress their transcription and expression to promote oncogenesis. In addition to its crucial function in oncogenesis, it plays a vital role in DNA repair. Overall, this review concisely summarizes the current knowledge about MORC2-regulated molecular pathways involved in cancer.

Screening of natural products atlas for identification of lead molecule to treat angina pectoris using bioinformatics approaches.

Angina pectoris is amongst the most common diseases. There is a scarcity of effective treatments for this disease. As a result, there is a significant clinical and social interest in predicting and developing novel compounds to treat cardiovascular disorders. So, specific natural products have been screened in this study because they have protective effects against angiotensin-converting enzymes. When taken orally, natural products can help protect against or lessen the severity of angina and heart damage. Natural compounds inhibit regulatory enzymes for controlling Angina. For this, we used computational methods such as drug design to identify novel natural compounds against cardiovascular diseases. Drug design via computational methods is gaining popularity as a quick and effective method to identify lead compounds in a shorter time at a low cost. This research work aims to predict novel lead inhibitor compounds against ACE to treat angina pectoris. This would ensure that, in early preclinical studies, there will be lower failure rates due to the demonstrated safety profiles of the predicted compounds.

The discovery of the natural compound Boeravinone-C as a potential antiobesity drug candidate targeting pancreatic lipase using chemo-informatics-based approaches.

Obesity is a metabolic disorder distinguished by excess fat deposition in fatty tissues. Pancreatic lipase is one of the promising drug targets for treating obesity due to its critical role in the hydrolysis of triglycerides into mono-glycerides and free fatty acids. Due to unsatisfactory results and severe side effects of the current drugs available for treating obesity, there is an urgent need to identify novel therapeutic options. Boerhaavia diffusa is one of the widely known species of flowering plant commonly known as Punamava. Extracts from Punamava plants have been widely used in treating countless ailments in traditional medicine. Recently, multiple reports demonstrated the potential antiobesity activity of B. diffusa plant extracts. In this scenario, we have evaluated numerous reported B. diffusa against pancreatic lipase drug targets to identify which reported phytochemicals to have the most promising potential to act as an inhibitor for pancreatic lipase using computational approaches. All the twenty-four phytochemicals from Boerhaavia diffusa were identified as significantly strong binders with a range of binding energies between -6.0 to -8.0 Kcal/mol inside the pancreatic lipase active binding site. On the other hand, we calculated 2D Quantitative Structure-Activity Relationship (QSAR) molecular descriptor properties adhered to Lipinski's rule of five. Between twenty-four phytochemicals evaluated, Boeravinone-C, with a range binding energy of -8.0 Kcal/mol, was discovered as the best lead-like molecule, compared to marketed Orlistat, which has shown -5.6 Kcal/mol of binding energy. Conclusively, Boeravinone-C from B. diffusa extract showed promising inhibitory potential against pancreatic lipase worth further evaluation.
