RESUMO
Erythrocytes undergo several changes during human aging and age-related diseases and, thus, have been studied as biomarkers of the aging process. The present study aimed to explore the antioxidant ability of metal and metal oxide nanoparticles (NPs) such as iron oxide (Fe3O4), gold (Au), and silver (Ag) to mitigate age-related oxidative stress in human erythrocytes. Metal and metal oxide NPs behave like antioxidative enzymes, directly influencing redox pathways and thus have better efficiency. Additionally, biopolymer coatings such as dextran enhance the biocompatibility of these NPs. Therefore, dextran-coated Fe3O4, Au, and Ag NPs were synthesized using wet chemical methods and were characterized. Their hemocompatibility and ability to protect erythrocytes from age-induced oxidative stress were investigated. The Fe3O4 and Au NPs were observed to protect erythrocytes from hydrogen peroxide and age-induced oxidative damage, including decreased antioxidant levels, reduced activity of antioxidative enzymes, and increased amounts of oxidative species. Pre-treatment with NPs preserved the morphology and membrane integrity of the erythrocyte. However, Ag NPs induced oxidative stress in erythrocytes similar to hydrogen peroxide. Therefore, dextran-coated Fe3O4 and Au nanoparticles have the potential to be employed as antioxidant therapies against age-related oxidative stress.
RESUMO
The mostly aggressive and extremely malignant type of central nervous system is Glioblastoma (GBM), which is characterized by an extremely short average survival time of lesser than 16 months. The primary cause of this phenomenon can be attributed to the extensively altered genome of GBM, which is characterized by the dysregulation of numerous critical signaling pathways and epigenetics regulations associated with proliferation, cellular growth, survival, and apoptosis. In light of this, different genetic alterations in critical signaling pathways and various epigenetics regulation mechanisms are associated with GBM and identified as distinguishing markers. Such GBM prognostic alterations are identified in PI3K/AKT, p53, RTK, RAS, RB, STAT3 and ZIP4 signaling pathways, metabolic pathway (IDH1/2), as well as alterations in epigenetic regulation genes (MGMT, CDKN2A-p16INK4aCDKN2B-p15INK4b). The exploration of innovative diagnostic and therapeutic approaches that specifically target these pathways is utmost importance to enhance the future medication for GBM. This study provides a comprehensive overview of dysregulated epigenetic mechanisms and signaling pathways due to mutations, methylation, and copy number alterations of in critical genes in GBM with prevalence and emphasizing their significance.
RESUMO
INTRODUCTION: Human epidemiological studies have shown that diets rich in plant polyphenols have beneficial effects on various diseases including cancer. Epigallocatechin Gallate, a flavonoid polyphenol molecule, has been shown to be both chemotherapeutic and chemo-preventive in the treatment of several forms of cancer, including lung cancer. 80% of cancers of the lungs are non-small cell lung cancers. OBJECTIVE: The study was carried out to see the effects of Epigallocatechin Gallate in non-small cell lung cancer cells (A549) using in-vitro studies. MATERIALS AND METHODS: Cell Viability Assay was performed using MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. Wound Healing assay was also performed at different concentrations of the compound. Dexamethasone and Doxorubicin, the drugs with anti-cancer properties served as control. A549 cell lines were used. RESULTS: In the current study, it was demonstrated using Cell viability assay and Wound Healing assay that Epigallocatechin gallate exhibits anti-proliferative activity on A549 lung cancer cells and inhibits cancer cell proliferation in a concentration and time-dependent manner. It was observed that Epigallocatechin gallate (P = 0.0016, P = 0.0018) could significantly inhibit the growth of lung cancer cells with IC50 values 60.55 ± 1.0 µM. The result of wound Healing assay suggests that Epigallocatechin gallate can inhibit the proliferation and migration of A549 cells with concentrations near or higher to 50 µM. CONCLUSION: Epigallocatechin gallate's protective effect has been shown in A549 lung adenocarcinoma cells in a time and dose-dependent manner. This suggests the implication of Epigallocatechin gallate for the prevention and therapy for lung cancer.
RESUMO
The role of messenger RNA (mRNA) in biological systems is extremely versatile. However, it's extremely short half-life poses a fundamental restriction on its application. Moreover, the translation efficiency of mRNA is also limited. On the contrary, circular RNAs, also known as circRNAs, are a common and stable form of RNA found in eukaryotic cells. These molecules are synthesized via back-splicing. Both synthetic circRNAs and certain endogenous circRNAs have the potential to encode proteins, hence suggesting the potential of circRNA as a gene expression machinery. Herein, we aim to summarize all engineering aspects that allow exogenous circular RNA (circRNA) to prolong the time that proteins are expressed from full-length RNA signals. This review presents a systematic engineering approach that have been devised to efficiently assemble circRNAs and evaluate several aspects that have an impact on protein production derived from. We have also reviewed how optimization of the key components of circRNAs, including the topology of vector, 5' and 3' untranslated sections, entrance site of the internal ribosome, and engineered aptamers could be efficiently impacting the translation machinery for molecular and metabolic reprogramming. Collectively, molecular and metabolic reprogramming present a novel way of regulating distinctive cellular features, for instance growth traits to neoplastic cells, and offer new possibilities for therapeutic inventions.

Cancer, being the most formidable ailment, has had a profound impact on the human health. The disease is primarily associated with genetic mutations that impact oncogenes and tumor suppressor genes (TSGs). Recently, growing evidence have shown that X-linked TSGs have specific role in cancer progression and metastasis as well. Interestingly, our genome harbors around substantial portion of genes that function as tumor suppressors, and the X chromosome alone harbors a considerable number of TSGs. The scenario becomes even more compelling as X-linked TSGs are adaptive to key epigenetic processes such as X chromosome inactivation. Therefore, delineating the new paradigm related to X-linked TSGs, for instance, their crosstalk with autosome and involvement in cancer initiation, progression, and metastasis becomes utmost importance. Considering this, herein, we present a comprehensive discussion of X-linked TSG dysregulation in various cancers as a consequence of genetic variations and epigenetic alterations. In addition, the dynamic role of X-linked TSGs in sex chromosome-autosome crosstalk in cancer genome remodeling is being explored thoroughly. Besides, the functional roles of ncRNAs, role of X-linked TSG in immunomodulation and in gender-based cancer disparities has also been highlighted. Overall, the focal idea of the present article is to recapitulate the findings on X-linked TSG regulation in the cancer landscape and to redefine their role toward improving cancer treatment strategies.

Nutraceuticals are products that provide both nutritional and therapeutic benefits. These compounds can slow the aging process and provide physiological effects shielding individuals from acute and chronic diseases. People's interests have shifted from allopathic to Ayurvedic to nutraceuticals in recent years. These are often common dietary supplements that have drawn customers worldwide because of their high nutritional safety and lack of adverse effects when used for a long time. Although conventional dosage forms, including pills, tablets, and semi-solids, are still available, they nevertheless have poorer bioavailability, less stability, and less effectiveness for targeted delivery of bioactives. The use of effective nanocomplex systems as nano-antioxidants using nanotechnology has become a promising field. Among its many uses, nanotechnology is mostly used to create foods and nutraceuticals that are more bioavailable, less toxic, and more sustainable. Additionally, it has been emphasized how precisely nano-pharmaceuticals for oxidative stress produce the desired effects. These improvements show improved antioxidant delivery to the target region, reduced leakage, and increased targeting precision. The outcomes demonstrated that oxidative stress-related illnesses can be effectively treated by lowering ROS levels with the use of nanonutraceuticals. The major ideas and uses of nano-nutraceuticals for health are outlined in this review, with an emphasis on reducing oxidative stress.

We have semi-synthesized a natural product 7-acetylhorminone from crude extract of Premna obtusifolia (Indian headache tree), which is active against colorectal cancer after probation through computational screening methods as it passed through the set parameters of pharmacokinetics (most important nonblood-brain barrier permeant) and drug likeliness (e.g., Lipinski's, Ghose's, Veber's rule) which most other phytoconstituents failed to pass combined with docking with EGFR protein which is highly upregulated in the colorectal carcinoma cell. The structure of 7-acetylhorminone was confirmed by single crystal X-ray diffraction studies and 1H NMR, 13C NMR, and COSY studies. To validate the theoretical studies, first, in vitro experiments were carried out against human colorectal carcinoma cell lines (HCT116) which revealed the potent cytotoxic efficacy of 7-acetylhorminone and verified preliminary investigation. Second, the drugability of 7-acetylhorminone interaction with serum albumin proteins (HSA and BSA) is evaluated both theoretically and experimentally via steady-state fluorescence spectroscopic studies, circular dichroism, isothermal titration calorimetry, and molecular docking. In summary, this study reveals the applicability of 7-acetylhorminone as a potent drug candidate or as a combinatorial drug against colorectal cancer.

The therapeutic application of flavonoids in the management of infectious diseases, cancers, chronic wounds, aging, and neurodegenerative disorders has been well documented in scientific literature. The citric flavonoid naringenin comes under the category of flavanone and exhibits a plethora of health benefits. Very few flavonoids such as curcumin, resveratrol, catechin, quercetin, and kaempferol have been studied to exert their anti-aging properties in humans. The effect of naringenin in the context of age-associated disorders in detail has not been elucidated yet. The databases used for the literature search were Science Direct, Google Scholar, and PubMed. More emphasis has been put on the recent literature on "naringenin" and its effect on "age-associated disorders." Almost all chronic degenerative disorders are characterized by oxidative stress and inflammatory response. The study aims at highlighting the reactive oxygen species-mediated activity of naringenin and the underlying molecular mechanism leading to the prevention of various age-associated disorders. Altogether, the review presents a systematic comprehension of the pharmaceutical and clinicopathological benefits of naringenin in age-associated disorders.

Red blood cells (RBCs) have emerged as biomarkers of the aging process as they undergo several changes in human aging and age-related diseases. The objectives of our study are to explore the effect of human aging on RBC indices, the strengths, therapeutic interventions, challenges, and future directions for using RBCs as a biomarker. Two online databases, PubMed and ScienceDirect, were used to search relevant studies using "RBCs as biomarkers of human aging," "red blood cells [MeSH Terms] AND biomarkers [MeSH Terms] AND human aging [MeSH Terms]," and "erythrocytes and human aging" as keywords. A total of 474 studies were identified, and after the removal of duplicates, excluding studies based on title, abstract, or full text, 74 studies and 48 additional studies found through cross-referencing were included in this systematic review. Based on the evidence, we concluded that RBC indices such as hemoglobin concentration, mean corpuscular volume, RBC distribution width, RBC membrane, oxidative stress, and metabolism change with human aging. Several studies have applied therapeutic interventions to RBCs, including dietary supplementation, phytochemicals, nanoparticles, and physical activity, to mitigate aging and related outcomes. Hence, the quality of life for older people and healthy aging can be improved by further investigating the RBC parameters, molecular mechanisms, and their implications for age-related health consequences.

Endometriosis is an estrogen-dependent chronic inflammatory disorder involving the placement and growth of endometrial tissue outside the uterine cavity. It is the most common multifactorial disease that affects the life quality of women in reproductive age. Due to its multicomponent nature, early diagnosis of the disease is challenging. Since many genetic, epigenetic alterations and non-genetic factors contribute to the pathology of endometriosis, devising a drug therapy that directly acts on the ectopic tissue is extremely difficult. Endometriosis is a hormone-driven disease with estrogen considered as a primary driver for the development of endometriotic lesions. This study aims to identify biosignatures involved in endometriosis with and without gonadotropin releasing hormone agonists (GnRHa). GnRHa is a short peptide analog of GnRH that causes inhibition of estrogen and androgen synthesis. Microarray based-gene expression profiling was performed on total RNA extracted from endometriotic tissue samples with and without GnRHa-treated patients already published in our previous paper. The untreated group were considered as the control. Genes were then selected for validation by quantitative real-time polymerase chain reaction (qRT-PCR). qRT-PCR analysis confirmed significant downregulation in(p < 0.05) expression of DARC (p = 0.0042), CDH1 (p = 0.0027), CDH5 (p = 0.0283), ATP2A3 (p < 0.001), RGS5 (p = 0.0032), and CD36 (p = 0.0162) in endometriosis patients treated with GnRHa analogs. Although, CTNNAL1 (p = 0.0136) also showed significant results but there was upregulation in their expression levels after GnRHa treatment. Thus, an altered expression of these genes makes them a possible candidate determinant of endometriosis treated with GnRHa.

In recent years, exploring the potential of miRNAs as novel diagnostic, prognostic and diagnostic markers have gained much attention. In current study, we conducted an in-depth circRNA-miRNA-mRNA interactome to reveal significant molecular processes and biological pathways putatively associated with endometrial cancer (EC). Firstly, we retrieved two circRNAs from circad, hsa_circ_0002577 & hsa_circ_0109046, based on their association with the EC. Subsequently, we predicted miRNAs sponging sites in the two circRNAs and the potential target mRNAs of the predicted miRNAs. Sequestered miRNAs target a number of oncogenes (CBL, MET, KRAS), tumor suppressor (CFT R), receptor protein kinases & GT Pase (MET, KRAS, RAB1B), methyltransferases (SET D8), receptors associated factors (T RAF2, GRB2), growth factors (FGF20), autophagy (BECN1, AT G14), apoptotic regulators (BCL2), transcription factors (T Fs) (CREB1, RUNX1, RUNX2) and gene regulators (CCND1, HIF1A); and others, including some novel gene candidates (CREB1, FGF20, IFI27), that have never been implicated in EC earlier. The expression of hsa-miR-433-3p showed significant predictive relevance (Fold Change = 1.8, AUC = 0.736, Mann-Whitney test p-value = 6.1 e- 14) suggesting its predictive relevance in assessing patients' response to chemotherapy. The hsamiR- 188-3p targets autophagic and apoptotic regulators and its upregulation in endometriosis may be used as for the early stage diagnostic purpose. The hsa-miR-502-5p targets SET D8, T RAF2 and others and suggests additional genomic/epigenomic molecular targets for promising therapeutic interventions in EC. Predicted miRNAs target a number of mRNAs having varied functional impacts and offer an in-depth mechanistic insights for expatiating the biological and regulatory role in EC.Communicated by Ramaswamy H.

RESUMO
Breast cancer is one of the major reason for death of women worldwide. As per the International Agency for Research on Cancer (IARC) statistics, the number of cases of breast cancer is increasing year by year in many parts of the world. As per the recent global cancer burden figures, in 2020, there were 2.26 million incidences of breast cancer cases and it is one of the main causes of mortality due to cancer in women in the world. Biomarkers of breast cancer would prove to be very beneficial to screen women who are at higher risk and for detection of disease recurrence. Here, studies carried out on biomarkers of breast cancer and susceptibility to the disease have been reviewed. Various databases like Google Scholar, ScienceDirect and PubMed have been used for searching and majorly literature from the last 10 years have been considered. Potential biomarkers of breast cancer including blood based angiogenic factors, glycoprotein-based biomarkers, hormone receptor biomarkers and other biomarkers that were identified from various studies have been summarized.

Endometriotic cells exhibit a notable degree of invasiveness and some characteristics of tissue remodeling underlying lesion formation. In this regard, do matrix metalloproteinases 14 (MMP14) and other related genes such as SPARC-like protein 1 (SPARCL1), caveolin 2 (CAV2), and clusterin (CLU) exert any significant influence in the processes of endometriosis development and pathophysiology is not apparent. We aim to assess whether these genes could serve as potential diagnostic biomarkers in endometriosis. Microarray-based gene expression analysis was performed on total RNA extracted from endometriotic tissue samples treated with and without gonadotropin-releasing hormone agonist (GnRHa). The GnRHa untreated patients were considered the control group. The validation of genes was performed using quantitative real-time polymerase chain reaction (qRT-PCR). qRT-PCR analysis showed significant downregulation in the expression of MMP14 (p = 0.024), CAV2 (p = 0.017), and upregulation of CLU (p = 0.005) in endometriosis patients treated with GnRHa. SPARCL1 did not show any significant (p = 0.30) change in the expression compared to the control group. These data have the potential to contribute to the comprehension of the molecular pathways implicated in the remodeling of the extracellular matrix, which is a vital step for the physiology of the endometrium. Based on the result, it is concluded that changes in the expression of MMP14, CAV2, and CLU post-treatment imply their role in the pathophysiology of endometriosis and may serve as a potential diagnostic biomarker of endometriosis in response to GnRHa treatment in patients with ovarian endometrioma.

Background: Endometriosis is defined as a condition in which a formation of abnormal endometrial tissue outside the uterus takes place. Irrespective of any ethnic and socioeconomic class, the prevalence of the diseases has been seen among women of reproductive age. Endometriosis has been seen adversely affect the physical, psychological, social, and career of women. Summary: This paper aims to identify and describe the experiences and outcomes of endometriosis healthcare by reviewing the existing literature on social and psychological effects of endometriosis. The study serves the purpose of providing insights on women's dual suffering (mental and social health) and critical comments on the present state of knowledge in order to make future recommendations for psycho-social research. The review included systematic search of the articles from various disciplines like, biology, psychology, sociology, anthropology, etc. A structured process of screening with specific inclusion and exclusion criteria was used to select the articles. The analysis of the articles resulted that woman diagnosed with endometriosis reported poor quality of life and the following symptoms such as anxiety, stress, Chronic Pelvic Pain (CPP), anxiety, dyspareunia, and dysmenorrhea. However, depression appears prominent among women diagnosed with endometriosis. There are few strategies mentioned that can be used to deal with endometriosis. Key Message: The most promising causes of endometriosis include abnormality in immune functioning, atypical endometriotic growth, genetics, epigenetic, embryogenetic theory, and endocrine disruptors. The ill effects have been noted in the following domains of women's life such as work, close relationships, social well-being, and education, deteriorating their quality-of-life manifold. Psychological intervention is required to deal with the disorder as only medical treatment with pain may not be sufficient. Though, the condition can be improved by providing awareness regarding the severity of the disorder at the school and community levels.
RESUMO
Endometriosis is one of the most severe female reproductive disorders, affecting 6-10% of women between 18 and 35. It is a gynaecological condition where endometrial tissue develops and settles outside the uterus. The aetiology of endometriosis is primarily influenced by genetic, epigenetic, and non-genetic variables, making it highly challenging to create a therapeutic therapy explicitly targeting the ectopic tissue. The delay in the treatment is due to the limitations in the diagnostic approaches, which are restricted to invasive techniques such as laparoscopy or laparotomy. This accords to 70% of the women being diagnosed at later stages. By understanding the subject, several treatment medications have been produced to lessen the disease's symptoms. Nevertheless, endometriosis cannot be permanently cured. A viable or persuasive standard screening test for endometriosis must be utilized in a clinical context. A helpful assessment method for the early identification of endometriosis could be biomarkers. A major research priority is the identification of a biomarker that is sensitive and specific enough for detecting endometriosis. The present article has reviewed studies published on the expression of biomarkers of endometriosis. It outlines various biomarkers from different sample types, such as serum/plasma and urine, in addition to tissue. This would provide a non-invasive approach to diagnosing the disease at the initial stages without any harmful repercussions. Future high-throughput advances in science and technology are anticipated to result in the creation of a potent remedy for endometriosis. To achieve successful outcomes, it is necessary to research the discussed biomarkers that demonstrate substantial results extensively.

Cerium oxide nanoparticles have now significant presence in biomedical fields due to their wide applications; however, challenges regarding their safety and biocompatibility persist. Polysaccharides based biopolymers have inherent hydroxyl and carboxyl groups, enabling them to govern the surface functionalization of cerium oxide nanoparticles, hence their chemical and physical characteristics. Because of this, polysaccharides such as dextran, alginate, pullulan, chitosan, polylactic acid, starch, and pectin are practical substitutes for the conventional coatings used to synthesize cerium oxide nanoparticles. This review discusses the effect of biopolymer coatings on the properties of cerium oxide nanoparticles, such as size, stability, aggregation, and biocompatibility. Additionally, it also summarises various biomedical applications of polysaccharides coated cerium oxide nanoparticles, such as in bone tissue regeneration, liver inflammation, wound healing, and antibacterial and anticancer activities. Biocompatible cerium oxide nanoparticles will surely improve their applications in the biomedical field.
