Human esophageal fibroblast-derived exosomal miR-21 reduced the cisplatin sensitivity to esophageal carcinoma EC9706 cells

Braz. j. med. biol. res; 54 (10), 2021
The objective of this study was to investigate the effect of human esophageal fibroblast-derived exosomal miR-21 on cisplatin sensitivity against esophageal squamous EC9706 cells. EC9706 cells were co-cultured indirectly with human esophageal fibroblasts (HEF) or miR-21 mimics transfected-HEF in the tran...

Discovery of the ARP2 protein as a determining molecule in tumor cell death

Gac. méd. Méx; 155 (5), 2019
Cancer is a multifactorial disease that constitutes a serious public health problem worldwide. Prostate cancer advanced stages are associated with the development of androgen-independent tumors and an apoptosis-resistant phenotype that progresses to metastasis. By studying androgen-independent lymphoid n...

Effect of microRNA-21 on the proliferation of human degenerated nucleus pulposus by targeting programmed cell death 4

Braz. j. med. biol. res; 49 (6), 2016
This study aims to explore the effect of microRNA-21 (miR-21) on the proliferation of human degenerated nucleus pulposus (NP) by targeting programmed cell death 4 (PDCD4) tumor suppressor. NP tissues were collected from 20 intervertebral disc degeneration (IDD) patients, and from 5 patients with traumati...

Evaluación de la actividad antiproliferativa y proapoptótica de compuestos kauranos sobre líneas celulares de leucemia humana

En Venezuela y el mundo, el cáncer es la segunda causa de morbi-mortalidad, y la leucemia es uno de los tipos de cáncer que afecta a nuestra población. La principal características de las celulas linfoides y mieloides presentes en la leucemia es que son pocos funcionales y además no responden a las ...
