Understanding the role of miRNAs in cervical cancer pathogenesis and therapeutic responses.

Cervical cancer (CC) is the most common cancer in women and poses a serious threat to health. Despite familiarity with the factors affecting its etiology, initiation, progression, treatment strategies, and even resistance to therapy, it is considered a significant problem for women. However, several factors have greatly affected the previous aspects of CC progression and treatment in recent decades.

Luteolin Causes 5'CpG Demethylation of the Promoters of TSGs and Modulates the Aberrant Histone Modifications, Restoring the Expression of TSGs in Human Cancer Cells.

Cancer progression is linked to abnormal epigenetic alterations such as DNA methylation and histone modifications. Since epigenetic alterations, unlike genetic changes, are heritable and reversible, they have been considered as interesting targets for cancer prevention and therapy by dietary compounds such as luteolin. In this study, epigenetic modulatory behaviour of luteolin was analysed on HeLa cells.

Fisetin Deters Cell Proliferation, Induces Apoptosis, Alleviates Oxidative Stress and Inflammation in Human Cancer Cells, HeLa.

Background: Fisetin, a flavonol profusely found in vegetables and fruits, exhibited a myriad of properties in preclinical studies to impede cancer growth.

Purpose: This study was proposed to delineate molecular mechanisms through analysing the modulated expression of various molecular targets in HeLa cells involved in proliferation, apoptosis and inflammation.

Methods: MTT assay, flow cytometry, nuclear morphology, DNA fragmentation and Annexin-Pi were performed to evaluate the anti-cancer potential of fisetin.

Oxidative Stress in Human Pathology and Aging: Molecular Mechanisms and Perspectives.

Reactive oxygen and nitrogen species (RONS) are generated through various endogenous and exogenous processes; however, they are neutralized by enzymatic and non-enzymatic antioxidants. An imbalance between the generation and neutralization of oxidants results in the progression to oxidative stress (OS), which in turn gives rise to various diseases, disorders and aging. The characteristics of aging include the progressive loss of function in tissues and organs.

Luteolin inhibits proliferation, triggers apoptosis and modulates Akt/mTOR and MAP kinase pathways in HeLa cells.

Flavonoids, a subclass of polyphenols, have been shown to be effective against several types of cancer, by decreasing proliferation and inducing apoptosis. Therefore, the aim of the present study was to assess the anti-carcinogenic potential of luteolin on HeLa human cervical cancer cells, through the use of a cell viability assay, DNA fragmentation assay, mitochondrial membrane potential assay, cell cycle analysis using Annexin/PI staining and flow cytometry, gene expression analysis and a protein profiling array. Luteolin treatment exhibited cytotoxicity towards HeLa cells in a dose- and time-dependent manner, and its anti-proliferative properties were confirmed by accumulation of luteolin-treated cells in sub-G phases.

In Silico Studies Reveal Antiviral Effects of Traditional Indian Spices on COVID-19.

Background: The global health emergency due to SARS-CoV-2 causing the COVID-19 pandemic emphasized the scientific community to intensify their research work for its therapeutic solution. In this study, Indian traditional spices owing to various medicinal properties were tested in silico for their inhibitory activity against SARS-CoV-2 proteins. SARS-CoV-2 spike proteins (SP) and main proteases (M) play a significant role in infection development were considered as potential drug targets.

Exploration of Lifestyle Choices, Reproductive Health Knowledge, and Polycystic Ovary Syndrome (PCOS) Awareness Among Female Emirati University Students.

Objective: Healthy lifestyle and adequate reproductive health knowledge are prerequisites for maintenance of physical and mental well-being of women across the world. With increasing prevalence of metabolic disorders such as polycystic ovary syndrome (PCOS), it is important that sufficient awareness of these issues is generated, especially in conservative communities in Arab regions. The main objective of this study is to assess reproductive health (RH) knowledge and awareness of PCOS among female Emirati students and also to explore their lifestyle choices.

A review on myricetin as a potential therapeutic candidate for cancer prevention.

Myricetin, one of the most extensively studied polyphenols, is present abundantly in various fruits and vegetables and exhibits diverse pharmacological properties. The multifaceted biological action of myricetin against tumor heterogeneity makes it an impressive anticancer agent whose efficacy has been confirmed by an overwhelming number of studies. Myricetin shows its therapeutic potential by targeting and modulating the expression of various molecular target which are involved in inflammation, cell proliferation, apoptosis, angiogenesis, invasion, and metastasis.
