MiR-30a-5p Alters Epidermal Terminal Differentiation during Aging by Regulating BNIP3L/NIX-Dependent Mitophagy.

Chronological aging is characterized by an alteration in the genes' regulatory network. In human skin, epidermal keratinocytes fail to differentiate properly with aging, leading to the weakening of the epidermal function. MiR-30a is particularly overexpressed with epidermal aging, but the downstream molecular mechanisms are still uncovered.

Effect of naringenin and its combination with cisplatin in cell death, proliferation and invasion of cervical cancer spheroids.

The main treatment alternative for cervical cancer is cisplatin chemotherapy. However, the resistance of tumor cells to cisplatin, in addition to side effects, limits its use. The flavonoid naringenin has shown cytotoxic effects on tumor cells and may be considered as a coadjuvant in the treatment of cervical cancer.

MYPT1 is targeted by miR-145 inhibiting viability, migration and invasion in 2D and 3D HeLa cultures.

The miR-143/145 cluster is down-regulated in cervical tumor cells suggesting a role in tumorigenesis including cytoskeleton remodeling, a key event for tumor progression. The aim of the present work was to determine the role of miR-143/145 in the modulation of the myosin regulator phospho-myosin light chain (pMLC). HeLa monolayer and tridimensional cultures were transfected with miR-143 or miR-145 mimics inhibiting cell viability, proliferation, migration and invasion, mainly through miR-145.

MARK1 is a Novel Target for miR-125a-5p: Implications for Cell Migration in Cervical Tumor Cells.

Background: Aberrant miRNA expression is associated with the development of several diseases including cervical cancer. Dysregulation of miR-125a-5p is present in a plethora of tumors, but its role in cervical cancer is not well understood.

Objective: The aim was to analyze the expression profile of miR-125a-5p in tumor and immortal cell lines with further target prediction, validation and function analysis.
