BACKGROUND: Gallbladder cancer (GBC) is the most common tumor of the biliary tract. The incidence of GBC shows a large geographic variability, being particularly frequent in Native American populations. In Chile, GBC represents the second cause of cancer-related death among women. We describe here the es...
BACKGROUND: Previous studies have shown that long noncoding RNA (IncRNA) LINC00483 was aberrantly expressed in human cancers, including gastric cancer. However, the regulatory mechanism of this IncRNA in gastric cancer remains largely unknown. The present study aimed to investigate the effect of LINC0048...
ABSTRACT Objective: To verify the physiological action of triiodothyronine T3 on the expression of transforming growth factor α (TGFA) mRNA in MCF7 cells by inhibition of RNA Polymerase II and the MAPK/ERK pathway Materials and methods: The cell line was treated with T3 at a physiological dose (10...
BACKGROUND: Arsenic trioxide (As2O3), a drug that has been used in China for approximately two thousand years, induces cell death in a variety of cancer cell types, including neuroblastoma (NB). The tyrosine kinase receptor (Trk) family comprises three members, namely TrkA, TrkB and TrkC. Various studies...
A família proteína quinases C (PKC) é composta por dez isoenzimas, as quais são capazes de fosforilar resíduos de serina e treonina. A ativação dessas quinases envolve mudanças conformacionais, como a remoção do pseudo-substrato do sítio ativo e associação dessas enzimas com lipídeos em mem...
