There is a unique microbial community in the female lower genital tract known as the vaginal microbiota, which varies in composition and density and provides significant benefits during pregnancy, reproductive cyclicity, healthy newborn delivery, protection from preterm birth, infections such as UTIs, bacterial vaginosis, and so on, and improves the efficacy of treatments for vaginal cancers. Methods: It is necessary to know how the vaginal microbiome is composed in order to make an accurate diagnosis of the diseases listed above. A microbiome’s members are difficult to classify, and the way microbial communities function and influence host–pathogen interactions are difficult to understand. More and more metagenomic studies are able to unravel such complexities due to advances in high-throughput sequencing and bioinformatics. When it comes to vaginal microbiota research, we’ll be looking at the use of modern techniques and strategies that can be used to investigate variations in vaginal microbiota in order to detect diseases earlier, better treat vaginal disorders, and boost women’s health. Discussion: The discussed techniques and strategies may improve the treatment of vaginal disorders and may be beneficial for women’s overall health.

The ubiquitously transcribed tetratricopeptide repeat Y-linked gene (UTY/KDM6C), a catalytically impaired histone demethylase encoded on the Y chromosome, has garnered increasing attention for its emerging roles in tumorigenesis and cancer progression. Despite high sequence homology with its X-linked paralog UTX/KDM6A, UTY exhibits markedly reduced or absent H3K27me3 demethylase activity due to critical amino acid substitutions in its Jumonji C domain. Consequently, UTY primarily functions through non-enzymatic mechanisms, acting as a scaffold in chromatin-remodelling complexes like COMPASS and SWI/SNF, or mediating protein–protein interactions that regulate transcriptional programs independent of demethylation. This aligns with epigenetic dysregulation in cancers, where imbalances in repressive H3K27me3 and active H3K4me either drive tumour suppressor silencing or oncogene activation. Unlike frequently mutated UTX in cancers such as breast, renal cell carcinoma, and acute myeloid leukaemia, UTY’s contributions in cancer are less defined, constrained by male-specific expression. Emerging evidence suggests UTY as a context-dependent tumour suppressor in AML and squamous-like pancreatic ductal adenocarcinoma. While direct functional validation remains limited in several cancer types, UTY is increasingly implicated as a potential tumour suppressor in haematological malignancies and prostate cancer. Therapeutically targeting UTY’s scaffold functions shows promise for male-specific cancers and merits future investigation.

Nanoparticles (NPs) are indeed a class of materials composed of a variety of metals or non-metal elements that have distinctive characteristics and a wide range of applications in research and medicine. The biological fabrication of nanoparticles using macro-microscopic entities such as plants, bacteria, fungus, seaweed, and microalgae is a low-cost, one-step approach that is also environmentally beneficial. Biosensing, photo catalysis, drug transport, imaging, nano device manufacture, and usage as antimicrobial agents and in medicine are all significant biological implications of nanoparticles. In recent years, multidrug-resistant pathogenic microbial strains have emerged, and the majority of current antibiotics are ineffective against them. Metallic nanoparticles due to their high surface area to volume ratio are efficient against a range of pathogenic microorganisms, which has sparked scientists’ interest in developing new antibiotics. Since nanoparticles attack numerous biomolecules at once and have the ability to generate ROS, they minimise the emergence of resistant strains and thus have the potential to diminish or eliminate the generation of more resistant bacteria. The one-pot green synthesis is expected to result in enhanced antimicrobial benefits by amplifying the particular plant extract’s ability to combat microbes. This opens the door for these NPs to be used in a variety of applications, including the production of effective antibacterial agents for the management of emerging multidrug-resistant pathogenic bacteria, leading to improved health, environmental protection, and the prevention of infectious illnesses.
