MicroRNAs (miRNAs, miRs) are short noncoding RNAs that act to repress expression of proteins from target mRNA transcripts. miRNAs influence many cellular processes including stemness, proliferation, differentiation, maintenance, and survival, and miRNA mutations or misexpression are associated with a variety of disease states. The miR-183 family gene cluster including miR-183, miR-96, and miR-182 is highly conserved among vertebrate and invertebrate organisms, and the miRNAs are coordinately expressed with marked specificity in sensory neurons and sensory epithelial cells. The crucial functions of these miRNAs in normal cellular processes are not yet fully understood, but expectedly dependent upon the transcriptomes of specific cell types at different developmental stages or in various maintenance circumstances. This article provides an overview of evidence supporting roles for miR-183 family members in normal biology of the nervous system, including mechanoreception for auditory and vestibular function, electroreception, chemoreception, photoreception, circadian rhythms, sensory ganglia and pain, and memory formation.

Both women and men are now confronted with the grave threat of cancers caused by the human papillomavirus (HPV). It is estimated that 80% of women may encounter HPV over their lives. In the preponderance of cases involving anal, head and neck, oral, oropharyngeal, penile, vaginal, vulvar, and cervical malignancies, high-risk HPV (HR-HPV) is the causative agent.

Background: Sorafenib, an FDA-approved drug for advanced hepatocellular carcinoma (HCC), faces resistance issues, partly due to myeloid-derived suppressor cells (MDSCs) that enhance immunosuppression in the tumor microenvironment (TME).
Methods: Various murine HCC cell lines and MDSCs were used in a series of in vitro and in vivo experiments. These included subcutaneous tumor models, cell viability assays, flow cytometry, immunohistochemistry, and RNA sequencing.
Background: The photothermal sensitivity of tobacco refers to how tobacco plants respond to variations in the photothermal conditions of their growth environment. The degree of this sensitivity is crucial for determining the optimal planting regions for specific varieties, as well as for improving the quality and yield of tobacco leaves. However, the precise mechanisms underlying the development of photothermal sensitivity in tobacco remain unclear.

Background: The process of B cell activation and plasma cell (PC) formation involves morphological, transcriptional, and metabolic changes in the B cell. Blocking or reducing PC differentiation is one approach to treat autoimmune diseases that are characterized by the presence of pathogenic autoantibodies. Recent studies have suggested the potential of myricetin, a natural flavonoid with anti-inflammatory and antioxidant properties, to block or reduce PC differentiation.

Metabolic reprogramming, the shifting from fatty acid oxidation to glucose utilization, improves cardiac function as heart failure (HF) progresses. Leptin plays an essential role in regulating glucose metabolism. However, the crosstalk between leptin and metabolic reprogramming is poorly understood.
