Alterations in miRNA Expression and Their Role in the Pathogenesis of Cervical Cancer.

Background: Cervical cancer has a high incidence and mortality rate, affecting more than half a million women in 2018. Its development is strongly related to high-risk HPV infection. After infection, several cellular molecules are affected, including microRNAs (miRNAs), which are the focus of our study.

Alteration in the Expression of Circular Rnas and its association with the Development and Progression of Osteosarcoma, an Integrative Review with High Sensitivity Research.

Background: Osteosarcoma is the most common primary malignant bone tumor, mainly affecting children, young adults, and the elderly. It is an aggressive cancer with a poor prognosis, exhibiting low survival rates even with standard treatment. Recently, circular RNA molecules capable of influencing gene expression through various functions, with their main role being acting as microRNA sponges and reducing their intracellular expression, have been identified.

Thimet oligopeptidase (THOP 1) distribution in cane toad (Bufo Marinus, Linnaeus, 1758) brain.

Thimet oligopeptides (THOP 1) is a metal-dependent peptidase involved in the metabolism of neuropeptides and the presentation of peptides via MHC-1. It has been shown to play a role in the regulation of protein-protein interactions and the metabolism of intracellular peptides. THOP 1 is associated with important biological processes such as metabolism and neurodegenerative diseases, among others.
