Drug resistance is a major impediment to successful chemotherapy in pancreatic cancer (PC) patients. We investigated the effect of Wnt/β-catenin signaling inhibition by wnt-c59 on chemoresistance in a trichostatin A-resistant Panc-1 cell line (Panc-1/TSA). Panc-1/TSA cells were treated with the Wnt/β‑catenin signaling inhibitor wnt-c59 (10 µmol · l-1) and/or trichostatin A (TSA; 10 µmol · l-1) ...

BACKGROUND The ability to evade apoptosis is one of the key properties of cancer. The apoptogenic effect of nickel nanowires (Ni NWs) on cancer cell lines has never been adequately addressed. Due to the unique physicochemical characteristics of Ni NWs, we envision the development of a novel anticancer therapeutics specifically for pancreatic cancer. Thus, we investigated whether Ni NWs induce R...

pantothenate kinase- associated neurodegeneration (pkan) syndrome is a rare autosomal recessive disorder characterized by progressive extrapyramidal dysfunction and iron accumulation in the brain and axonal spheroids in the central nervous system. it has been shown that the disorder is caused by mutations in pank2 gene which codes for a mitochondrial enzyme participating in coenzyme a biosynthe...

Background: Promoter hyper-methylation of tumor suppressor genes is a common event that occurs in cancer. As methylation is a reversible modification, agents capable of reversing an abnormal methylation status should help to combat cancer. 5-Aza-CdR is a DNA methyl-transferase inhibitor. The present study aimed to evaluate the effect of 5-Aza-CdR on the proliferation of human pancreatic cancer ...

O objetivo deste artigo teórico é discutir o papel dos quintais com Plantas Alimentícias Não Convencionais (PANC) como espaços produtores de educabilidade para uma Educação Ambiental crítica. Para tanto, abordaremos sistema agroalimentar hegemônico e a relação negação ao Direito Humano à Alimentação Adequada. Logo após, confrontaremos tal anúncio da agroecologia. Por meio duas temáticas: possib...

Coenzyme A analogues are synthesized in a one-pot preparation by biotransformation of pantothenate thioesters through the simultaneous use of three CoA biosynthetic enzymes, followed by aminolysis.

S100A11, a member of S100 calcium-binding protein family, is associated with the numerous processes of tumorigenesis and metastasis. In the present study, the role of S100A11, and its possible underlying mechanisms in cell proliferation, apoptosis and cell cycle distribution in human pancreatic cancer were explored. Immunohistochemical analyses of S100A11 and phosphorylated (p)-AKT serine/threo...
