Gut Microbiota Modification via Glucagon-like Peptide-1 with Beneficial Neuroprotective Effects.

: In recent decades, it has been shown that the association between intestinal bacterial imbalance (dysbiosis) and various diseases such as type 2 diabetes can play a role in the development of Alzheimer's and Parkinson's diseases. In this study, the beneficial effects of intestinal microbiota glucagon-like peptide 1 (GLP-1) in cognitive disorders were investigated. : PubMed-Medline, Web of Science, and Scopus were searched to identify experimental studies based on the bacterial strains along with GLP-1 1 expression in preventing or reducing cognitive impairment.

Diagnostic Significance of Serum Fatty Acid Synthase in Patients with Pancreatic Cancer.

BACKGROUND Pancreatic cancer is considered as the most deadly tumor among gastrointestinal cancers because of its poor prognosis. The frequently deregulated pathway in the cancer cell is associated with an increased expression of various genes, including the synthesis of fatty acids. We aimed to evaluate the level of serum fatty acid synthase (FASN) as a diagnostic marker for early diagnosis of pancreatic cancer.

Dehydroepiandrosterone modulates oxidative DNA damage in pancreatic cancer: A case-control study.

Background And Aim: Dehydroepiandrosterone (DHEA) has a protective role against several types of cancer, although its mechanisms of action are still unknown, it may be related to the antioxidant effect of DHEA. We hypothesized that DHEA has a preventive effect on the formation of the 8-hydroxy-2'-deoxyguanosine (8-OHdG) DNA adduct in pancreatic cancer patients.

Methods: Serum DHEAs were quantified by the ELISA method in 50 pancreatic cancer patients with histopathological diagnosis of adenocarcinoma and 50 matched controls.

An Increased Level of Aryl Hydrocarbon Receptor in Patients with Pancreatic Cancer.

BACKGROUND Aryl-carbon receptor (AhR), a ligand-activated transcription factor, is best known for its ability to mediate the effects of environmental toxins such as 2,3,7,8-tetrachlorodibenzo-p-dioxin. AhR is expressed in several tumor cells and regulates the expression of genes in the signal transduction pathways. In this study, we examined the soluble levels of AhR in patients with pancreatic cancer.

Detection of TP53 R249 Mutation in Iranian Patients with Pancreatic Cancer.

The TP53 gene encodes tumor protein p53 which play a major role in the etiology of pancreatic cancer. The important role of codon 249 of TP53 for binding of p53 to its sequence-specific consensus site in DNA has been revealed by crystallography's studies, and mutation at this codon was detected in the plasma of some human cancers. The TP53 Mut assessor software within the International Agency for Research on Cancer (IARC) TP53 Database was performed to evaluate every possible mutation at codon 249.
