Emerging biologic and clinical implications of miR-182-5p in gynecologic cancers.

MicroRNAs (miRNAs) have emerged as important regulators of gene expression in various biological processes, including cancer. miR-182-5p has gained attention for its potential implications in gynecologic cancers, including breast, ovarian, endometrial, and cervical cancers. miR-182-5p dysregulation has been associated with multiple facets of tumor biology in gynecologic cancers, including tumor initiation, progression, metastasis, and therapeutic response.

The paradox of : how does infection protect against esophageal cancer?

is a microaerophilic gram-negative bacterium infecting around half of the world's population. Despite its well-known role in gastric malignancies, its impact on esophageal cancer comes with a complex paradox. Several mechanisms have been proposed to explain its observed lack of carcinogenic activity in the esophagus, including the trigger of anti-inflammatory pathways, promoting atrophic gastritis, and esophageal microbiome modulation.

Revolutionized attitude toward recurrent pregnancy loss and recurrent implantation failure based on precision regenerative medicine.

Traditional treatment strategies for recurrent pregnancy loss (RPL) and recurrent implantation failure (RIF) often result in limited success, placing significant emotional and financial burdens on couples. However, novel approaches such as diagnostic gene profiling, cell therapy, stem cell-derived exosome therapy, and pharmacogenomics offer promising, personalized treatments. Combining traditional treatments with precision and regenerative medicine may enhance the efficacy of these approaches and improve pregnancy outcomes.
