The role of IL-2 cytokine family in asthma.

BACKGROUND: The interleukin-2 (IL-2) family of cytokines, including IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21, are pivotal regulators of the immune response, impacting both innate and adaptive immunity. Understanding their molecular characteristics, receptor interactions, and signalling pathways is essential for elucidating their roles in health and disease. OBJECTIVES: This review provides a comprehensive overview of the IL-2 family of cytokines, highlighting their molecular biology, receptor interactions, and signalling mechanisms. Furthermore, it explores the involvement of IL-2 family cytokines in the pathogenesis of chronic respiratory diseases, with a specific focus on chronic obstructive pulmonary disease (COPD) and asthma. METHODS: A thorough literature review was conducted to gather insights into the molecular biology, receptor interactions, and signalling pathways of IL-2 family cytokines. Additionally, studies investigating the roles of these cytokines in chronic respiratory diseases, particularly COPD and asthma, were analysed to discern their implications in wider pathophysiology of disease. RESULTS: IL-2 family cytokines exert pleiotropic effects on immune cells, modulating cellular proliferation, differentiation, and survival. Dysregulation of IL-2 family cytokines has been implicated in the pathogenesis of chronic respiratory illnesses, including COPD and asthma. Elevated levels of IL-2 and IL-9 have been associated with disease severity in COPD, while IL-4 and IL-9 play crucial roles in asthma pathogenesis by promoting airway inflammation and remodelling. CONCLUSION: Understanding the intricate roles of IL-2 family cytokines in chronic respiratory diseases provides valuable insights into potential therapeutic targets for these conditions. Targeting specific cytokines or their receptors may offer novel treatment modalities to attenuate disease progression and improve clinical outcomes in patients with COPD and asthma.

Enhancing bio-hydrogen and bio-methane production of concentrated latex wastewater (CLW) by Co-digesting with palm oil mill effluent (POME): Batch and continuous performance test and ADM-1 modeling.

This study aimed at investigating the biohydrogen and biomethane potential of co-digestion from palm oil mill effluent (POME) and concentrated latex wastewater (CLW) in a two-stage anaerobic digestion (AD) process under thermophilic (55 ± 3 °C) and at an ambient temperature (30 ± 3 °C) conditions, respectively. The batch experiments of POME:CLW mixing ratios of 100:0, 70:30, 50:50, 30:70, and 0:100 was investigated with the initial loadings at 10 g-VS/L. The highest hydrogen yield of 115.57 mLH2/g-VS was obtained from the POME: CLW mixing ratio of 100:0 with 29.0 of C/N ratio. While, the highest subsequent methane production yield of 558.01 mLCH4/g-VS was achieved from hydrogen effluent from POME:CLW mixing ratio of 70:30 0 with 21.8 of C/N ratio. This mixing ratio revealed the highest synergisms of about 9.21% and received maximum total energy of 19.70 kJ/g-VS. Additionally, continuous hydrogen and methane production were subsequently performed in a series of continuous stirred tank reactor (CSTR) and up-flow anaerobic sludge blanket reactor (UASB) to treat the co-substate. The results indicated that the highest hydrogen yield of POME:CLW mixing ratio at 70:30 of 95.45 mL-H2/g-VS was generated at 7-day HRT, while methane production was obtained from HRT 15 days with a yield of 204.52 mL-CH4/g-VS. Thus, the study indicated that biogas production yield of CLW could be enhanced by co-digesting with POME. In addition, the two-stage AD model under anaerobic digestion model no. 1 (ADM-1) framework was established, 9.10% and 2.43% of error fitting of hydrogen and methane gas between model simulation data and experimental data were found. Hence, this research work presents a novel approach for optimization and feasibility for co-digestion of POME with CLW to generate mixed gaseous biofuel potentially.

Experimental Validation of MHC Class I and II Peptide-Based Potential Vaccine Candidates for Human Papilloma Virus Using Sprague-Dawly Models.

Human papilloma virus (HPV) causes cervical and many other cancers. Recent trend in vaccine design is shifted toward epitope-based developments that are more specific, safe, and easy to produce. In this study, we predicted eight immunogenic peptides of CD4+ and CD8+ T-lymphocytes (MHC class I and II as M1 and M2) including early proteins (E2 and E6), major (L1) and minor capsid protein (L2). Male and female Sprague Dawly rats in groups were immunized with each synthetic peptide. L1M1, L1M2, L2M1, and L2M2 induced significant immunogenic response compared to E2M1, E2M2, E6M1 and E6M2. We observed optimal titer of IgG antibodies (>1.25 g/L), interferon-γ (>64 ng/L), and granzyme-B (>40 pg/mL) compared to control at second booster dose (240 µg/500 µL). The induction of peptide-specific IgG antibodies in immunized rats indicates the T-cell dependent B-lymphocyte activation. A substantial CD4+ and CD8+ cell count was observed at 240 µg/500 µL. In male and female rats, CD8+ cell count for L1 and L2 peptide is 3000 and 3118, and CD4+ is 3369 and 3484 respectively compared to control. In conclusion, we demonstrated that L1M1, L1M2, L2M1, L2M2 are likely to contain potential epitopes for induction of immune responses supporting the feasibility of peptide-based vaccine development for HPV.

Myeloid Sarcoma - a diagnostic challenge in paediatric practice.

Myeloid Sarcomas are rare tumours of myeloid origin that may infiltrate multiple sites of the body. They may precede acute myeloid leukaemia or present without it. It has non-specific manifestations and presents as a diagnostic and therapeutic challenge owing to the limited literature that reports consensus on diagnostic and treatment strategies. Immunohistochemistry is of significance in identifying the disease and acute myeloid leukaemia protocols of systemic therapy remain the mainstay of the treatment. Our report of an 11-year-old child with myeloid sarcoma aims to add to the limited existing literature and describe the varied presentation and sites of involvement.

Association study of NAT2 gene polymorphism and risk of oral cancer in Southern Punjab, Pakistan.

OBJECTIVE: To investigate the single nucleotide polymorphic variations of N-acetyltransferase 2, phase-II metabolising enzyme, and associated risk factors for oral cancer. METHODS: The case-control study was conducted from November 2017 to April 2018 after approval from the Institute of Molecular Biology and Biotechnology, Bahauddin Zakariya University, Multan, Pakistan, and comprised oral cancer patients and healthy controls. Single nucleotide polymorphism of the N-acetyltransferase 2 gene associated with oral cancer was analysed. Factors assessed using tetra-primer amplification refractory mutation system polymerase chain reaction included age, smoking, naswar, betel leaves and nuts. RESULTS: Of the 201 subjects, 94(47%) were patients and 107(53%) were controls, while 108(54%) were aged 10-30 years. Single nucleotide polymorphism rs1208 of N-acetyltransferase 2 gene was primarily A803G and Lys268Arg, with allelic frequency of G/A. Age range 51-70 was significantly (p=0.00001) associated with the prevalence of oral cancer in terms of genotypic relationship with A803G. Substantial allelic association was found between the gene and oral cancer (p=0.006895). Smoking increased the cacner risk 7-fold (odds ratio: 7.0). CONCLUSIONS: The genetic variant of N-acetyltransferase 2 rs1208 was found to be significantly associated with oral cancer progression and development of associated risk factors.

Design, synthesis and biological evaluations of 2-aminothiazole scaffold containing amino acid moieties as anti-cancer agents.

Due to the emerging mortality rate of colorectal cancer there is a high need for the management and control of this disease. Although several treatment approaches are being developed day by day yet the high incidence rate of colorectal cancer is still not controlled. To ease in the development of treatment therapies for colorectal cancer two derivatives of ethyl 2-aminothiazole 4-carboxylate were designed and synthesized. The compounds Ethyl 2-(2-(1,3-dioxoisoindolin-2-yl)acetamido)thiazole-4-carboxylate (5a) and ethyl 2-(2-(1,3-dioxoisoindolin-2-yl)-3-phenylpropanamido)thiazole-4-carboxylate (5b) were characterized and studied for their anti-cancer activities. The in silico molecular modeling studies were performed against the target protein beta-catenin which is an important player in the progression of colorectal cancer. The in silico ADMET studies were performed to assess the basic physicochemical properties of these compounds. The in vitro antiproliferative assay and the enzyme inhibitory assay was performed to validate the role of these compounds in the colorectal cancer. The preliminary cytotoxic assay and the MTT assay of the compounds 5a and 5b against the colorectal cancer cell line HCT 116 showed 60% inhibition of cell proliferation with IC50 of 0.72µM and 1.55µM, respectively. The standard methotrexate showed IC50 of 0.7µM showing potent inhibitory action of these compounds. The in vitro validation of the anti-cancer effect of both compounds revealed significant inhibition of beta-catenin concentration at higher doses as compared to control. Both the in vitro and in vivo assays of compounds showed effective anti-cancer activities and depicts the future potential of these compounds in colorectal cancer.

Antitumor activity and combined inhibitory effect of ceritinib with gemcitabine in pancreatic cancer.

Pancreatic cancer (PC) is predominantly incurable and is primarily treated with gemcitabine, but drug resistance commonly develops. Thus, new medicines are needed. Ceritinib (LDK378) is a second-generation tyrosine kinase inhibitor of anaplastic lymphoma kinase (ALK) with antitumor activity in various cancers. However, studies involving ceritinib for the treatment of PC are inadequate. We analyzed the combined effects of ceritinib and gemcitabine on PC and their mechanism of action. Three PC cell lines were used to evaluate the antitumor effects of ceritinib combined with gemcitabine. We analyzed cell viability using CCK-8 assays, determined apoptosis levels through flow cytometry, and analyzed autophagy and cell signaling pathways by Western blotting and tissue array analysis with samples from xenograft models. Ceritinib strongly inhibited the proliferation of PC cells in a dose-dependent manner, induced apoptosis, and inhibited autophagy and cell migration by regulating relevant factors. Ceritinib in combination with gemcitabine exhibited significant growth inhibition and additive antitumor effects in vitro. In vivo, gemcitabine and ceritinib reduced tumor size by up to 30%. In our study, ALK was shown to be highly expressed in various PC cells and tissues. Ceritinib strongly inhibited the levels of activated ALK in PC cells with subsequent effects on the downstream mediators STAT3, AKT, and ERK. In addition, ceritinib inhibited tumor progression in xenograft models. Overall, our research shows that ceritinib inhibits the ALK signaling pathway, leading to cell growth/angiogenesis inhibition in PC and the induction of apoptosis. We recommend using ceritinib as a new treatment for PC.NEW & NOTEWORTHY These data proved that ceritinib inhibits the anaplastic lymphoma kinase signaling pathway, leading to cell growth/angiogenesis inhibition and the induction of apoptosis by inhibiting STAT3, AKT, and ERK pathway in pancreatic cancer (PC). We recommend using ceritinib as a new treatment for PC.

Experimental analysis of T cell epitopes for designing liver cancer vaccine predicted by system-level immunoinformatics approach.

Liver cancer is a worldwide disease, and, currently, due to the poor prognostic and therapeutic options of liver cancer, we investigated the T cell epitopes as potential therapeutic vaccine candidates to get the benefit of experimental processes and utilize the complete ability of the immune system compared with other artificial ex vivo proliferation of T cells. Activation of T cells targets and kills several tumors, developing a strong rationale for the improvement of immunotherapeutic strategies to cancer therapy. To predict T cell epitopes for liver cancer, we designed a comprehensive immunoinformatics framework involving data mining, immunogenicity prediction, functional proteomic analysis, conservation studies, molecular modeling, and in vivo validation analysis. We found the binding affinity of antigenic peptides with major histocompatibility complex (MHC) I molecules to control the cancerous activity. Five extracellular antigenic proteins, including complement protein (C6), serotransferrin, coagulation factor XIII B, serum albumin (ALB), and prothrombin, were identified. We predicted and synthesized T cell epitopes to human leukocytes antigen-A*01:01 allele of MHC class I molecule. The hematological assay and IgG ELISA showed that C6 and ALB epitopes induced the production of lymphocytes, granulocytes, and peptide-specific IgG in immunized rats. We observed substantial high levels of granzymes B in serum samples of C6 and ALB compared with control, indicating the activity of cytotoxic T cells. We concluded that C6 and ALB are likely to contain potential epitopes for the induction of protective effector molecules, supporting the feasibility of therapeutic peptide-based vaccine for liver cancer.NEW & NOTEWORTHY We observed substantial high levels of granzymes B in serum samples of component C6 (C6) and albumin (ALB) compared with control, indicating the activity of cytotoxic T cells.

Mini-Review: molecular elucidations of hutchinson-gilford progeria syndrome: A hope for managing horrors of premature aging in children.

Hutchinson-Gilford Progeria syndrome (or Progeria) is an exceptionally rare genetic disorder in children. It is caused by a rare point mutation in the lamin gene. It encodes lamin A protein, resulting in the de-shaping of nuclear membrane. This altered structure of the nuclear membrane renders the nucleus unstable. The shortened lifespan of the nucleus makes the cell liable for rapid ageing. Children are healthy by appearance when they are born but the signs appear after 12-24 months of age. Cardiovascular system is greatly affected which became a reason for the death of most of the patients of progeria. Stiffened joints disturb the bone movements; and alopecia affects the appearance of the patient. Rate of occurrence of the disease is one per four hundred thousand of people, though both sexes are equally affected.

Antibacterial activity and characterization of zinc oxide nanoparticles synthesized by microalgae.

Biosynthesis of zinc oxide nanoparticles (ZnO-NPs) using microalgae is novel and cost-effective approach. We studied production, molecular characterization, and antibacterial activity. Filtrates of isolated microalgae strain ZAA1 (MF140241), ZAA2 (MF114592) and ZAA3 (MF114594) were used. Incubation of these strains in 5mM solution of zinc nitrate was resulted in the synthesis of ZnO-NPs. Fourier-transform infrared, UV-visible spectroscopy and scanning electron microscopy were used to characterize the nanoparticles. Significant antibacterial activity of ZnO-NPs was measured against Escherichia coli, Staphylococcus aureus, Micrococcus luteus, Klebsiella pneumoniae and Citrobacter freundii. The microalgae mediated ZnO-NPs production is a successful procedure that can be used in a wide range of biomedical applications.

Protective effects of maresin 1 against inflammation in experimentally induced acute pancreatitis and related lung injury.

Severe acute pancreatitis (SAP) is an inflammatory disorder that progresses with local and systemic difficulties accompanied by a relatively high mortality rate. In recent years, maresin 1 (MaR1) has been shown to be a macrophage mediator with effective proresolving and anti-inflammatory properties that prevents the occurrence of various inflammatory conditions. The purpose of this study was to investigate the role of MaR1 in SAP and related lung injury. Experimental SAP was induced in mice with a combination of cerulean and lipopolysaccharide. MaR1 was administered 30 min before the primary injection of cerulean. Biochemical markers and histological injury scores were used to evaluate the severity of acute pancreatitis. To determine the degree of inflammation, serum cytokines and myeloperoxidase activity in pancreas and lung tissues were measured. Western blot analysis detected the activation of NF-κB. After MaR1 pretreatment, the activities of amylase, lipase, TNF-α, IL-1ß, and IL-6 were decreased in serum, and the myeloperoxidase activity both in pancreas and in lung tissues significantly decreased, whereas the activity of anti-inflammatory cytokine IL-10 in serum was increased. MaR1-pretreated mice reduced the activation of pancreatic NF-κB and decreased the severity of pancreatic and lung-related injuries. These results confirm that MaR1 alleviated inflammation of the pancreas and lung by inhibiting the activity of NF-κB in experimentally induced acute pancreatitis and exerted anti-inflammatory effects. These findings suggest that MaR1 could be a new and useful drug in the treatment of SAP.NEW & NOTEWORTHY These results provided us evidence to confirm that maresin 1 (MaR1) can alleviate inflammation of the pancreas and lung by inhibiting the activity of NF-κB in experimental induced acute pancreatitis and exerts certain anti-inflammatory effects. These findings suggest that MaR1 could be a new and useful drug in the treatment of severe acute pancreatitis.

REVIEW- Contemporary evidence on the dynamic role of probiotics in liver diseases.

Currently probiotics are considered as an emerging therapeutic strategy in the treatment of many liver disorders. The use of probiotics beyond infection of intestinal flora is a very helpful approach. The optimistic effect of probiotics has been observed in treating the hepatic cirrhosis, hepatic encephalopathy, viral hepatitis, irritable bowel syndrome, non-alcoholic fatty liver and alcoholic liver disease. The characterize mechanisms of probiotics are still unknown but may involve in, maintaining a microbial barrier against potential pathogens, reducing the production of bacterial toxins, modulating the immune system, intestinal permeability, and the inflammatory response. Its safety issues, effectiveness, food supplements as its source are still to be studied. However, studies revealed that probiotic therapy in hepatocellular carcinoma and in portal hypertension are still weak. Larger clinical studies are required before probiotics can be recommended as a treatment modality in liver diseases.

Optimisation of a modified submerged bed biofilm reactor for biological oleochemical wastewater treatment.

Oleochemicals industry effluence mainly contains a high chemical oxygen demand (COD) in a range of 6000-20,000 ppm. An effective biological wastewater treatment process must be carried out before wastewater is discharged into the environment. In this study, a submerged bed biofilm reactor (SBBR) was adapted to the biological oleochemical wastewater treatment plant observed in the present study. The effect of wastewater flow rate (100-300 mL/min), Cosmoball® percentage in the SBBR system (25-75%), and percentage of activated sludge (0-50%) were investigated in terms of COD reduction. The Box-Behnken design was used for response surface methodology (RSM) and to create a set of 18 experimental runs, which was needed for optimising the biological oleochemical wastewater treatment. A quadratic polynomial model with estimated coefficients was developed to describe COD reduction patterns. The analysis of variance (ANOVA) shows that the wastewater flow rate was the most effective factor in reducing COD, followed by activated sludge percentage and Cosmoball® carrier percentage. Under the optimum conditions (i.e., a wastewater flow rate of 103.25 mL/min a Cosmoball® carrier percentage of 71.94%, and an activated sludge percentage of 40.50%) a COD reduction of 98% was achieved. Thus, under optimum conditions, as suggested by the BBD, SBBR systems can be used as a viable means of biological wastewater treatment in the oleochemicals industry.

Effect of glycine: Studying memory and behavioral changes in mice.

Glycine is an important chemical mediator of nervous system that plays a vital role in memory and other neurological functions. Therefore, the effect of glycine on these traits must be studied to understand biological mechanisms of intricate neurological system. We investigated the effect of different doses of glycine on memory and behavior using 30 albino mice models (treated and control). After two weeks of glycine dosing, we performed light and dark activity and novel-object recognition (NOR) tests to assess the cognitive traits. Brain and blood samples were taken and kept at -70°C using ultra-low temperature freezer. Neurochemical estimation of blood glycine level was estimated by high-performance liquid chromatography with electrochemical detectors (HPLC-ECD). Concentration of glycine (100, 300 and 500 mg/kg) is significantly observed (p<0.01) and it changes due to physiological variations in N-methyl-Daspartate (NMDA) an important neurotransmitter for memory. We observed significant increase in serotonin metabolites including 5-hydroxy tryptophan (5-HT, p<0.05) and 5-hydroxy indole acetic acid (5-HIAA, p<0.001) levels. Similarly,effects were found in case of dopamine (DA, p<0.05) and its metabolites: 3, 4-Dihydroxyphenylacetic acid (DOPAC,p<0.001) and homovanillic acid (HVA, p<0.001). Histopathological investigation of brain tissues showed cellular clumps at cortical junctions at higher doses of glycine as compared to control. These findings revealed that dose dependent concentration of glycine can be useful for memory loss and behavior deficits.

Assessment of the risk factors of hypertension among adult & elderly group in twin cities of Pakistan.

OBJECTIVE: To estimate the prevalence of hypertension and to explore the risk factors associated with it. METHODS: In a cross-sectional study, a population based survey was conducted on inhabitants of Rawalpindi-Islamabad region, 219 individuals; aged 18 years or above were included in the study. Blood pressure was measured along with information about individual's demographic and socio-economic characteristics were obtained using a standard questionnaire.. RESULTS: Overall prevalence of hypertension was 29.22% (males: 21.9% and females: 78.1%) in individuals residing in Rawalpindi-Islamabad. High blood pressure is more associated with obesity (59.4%) and a progressive increase in hypertension was observed with increasing age. Bivariate analysis revealed that hypertension has a significant correlation (p-value<0.05) with age, gender, family status, weight and physical health. CONCLUSIONS: The study concludes that our generation is well aware about the risks and consequences of hypertension, but they still continue to make no or little effort in managing or preventing it. The factors contributing to hypertension are low physical activity, diet and lack of interest to maintain their health.

Report: Computational drug designing of newly synthesized triazoles against potential targets of methicillin resistant Staphylococcus aureus.

Methicillin resistant Staphylococcus aureus (MRSA) is resistant to known antibiotics and has become a great challenge for healthcare professionals, therefore new molecules are needed to manage this situation. In this study, new lead molecules 4-Amino-5-(2-Hydroxyphenyl)-1,2,4-Triazol-3-Thione (U1) and4-(2-hydroxybenzalidine) amine-5-(2-hydroxy) phenyl-1,2,4-triazole-3-thiol(U1A Schiff base) were synthesized by fusion method that showed promising antibacterial activity (U1A: 26mm and U1: 14mm) against MRSA.FT-IR and NMR were used for structural characterization of these derivatives and their toxicity properties were assessed by Lipinski's rule of 5. New potential drug targets of this bacterium were also identified by comparative and subtraction genomics techniques. In particular, octanoyl-[GcvH]: protein N-octanoyl transferase and phosphor mevalonate kinase were used as potential targets in AutoDock Vina studies. This study can provide a framework to find potential drug targets for other pathogenic microorganisms that can successfully be docked with compound U1 and U1A.

Report: Analgesic and anti-inflammatory activity of aqueous-methanolic extract of Aerva javanica.

The present study was aimed to investigate the analgesic and anti-inflammatory activity of aqueous methanolic extract of Aerva javanica. For measuring analgesic activity, writhing test, hot plate method and formalin test were performed and abdominal writhing was induced by intra-peritoneal injection of 0.2ml of 3% acetic acid. While in formalin test, pain was experimentally induced by injecting 25 µl of 2.5% formalin in left hind paw. In hot plate method, pain was induced thermally by keeping the animals on a hot plate with temperature of about 51°C. Anti-inflammatory activity was assessed by carrageen an induced mice paw edema. The results showed that the extract had significant analgesic activity (p<0.05- p<0.001) and anti-inflammatory activity (p<0.01-p<0.001). Therefore, it was concluded from this study that the extracts of Aerva javanica may be used against pain and inflammation.

Anti-proliferative and computational studies of two new pregnane glycosides from Desmidorchis flava.

Two new pregnane glycosides named desmiflavasides C (1) and D (2) were isolated from the sap of Desmidorchis flava (N.E.Br.) Meve & Liede and have had their structures confirmed from 1D and 2D NMR spectroscopic techniques and mass spectrometry (ESIMS). Further, the effects of desmiflavasides C (1) and D (2) on the proliferation of breast and ovarian cancer cells as well as normal breast epithelial cells in culture were examined. Interestingly, desmiflavasides C (1) and D (2) were able to cause a substantial decline in the viability of cancer cells in a concentration-dependent manner. Moreover, treatment of normal cells with compound 2 resulted in no significant growth inhibition, indicating that its cytotoxicity was selective towards cancer cells. Furthermore, the activity of compound 2 against cancer as well as normal epithelial cells was found to be similar to that of a previously reported pregnane glycoside, nizwaside (3). Molecular docking studies of desmiflavasides C (1) and D (2) and nizwaside (3) were carried out to ascertain if it was possible to predict any important binding orientations required of small molecule drug candidates with suggested protein target molecules for the purposes of being able to predict the affinity and activity to an acceptable degree by such compounds. Desmiflavaside D (2) showed a relatively good binding affinity (-22.4449kcal/mol) as compared to the other two compounds viz., nizwaside (3) (-20.0319kcal/mol), and desmiflavaside C (1) (-19.4042kcal/mol). Docking results of the three pregnane glycosides viz., 1-3 revealed that these ligand molecules can accurately interact with the target protein.
