Current perspectives of mi-RNA in oesophageal adenocarcinoma: Roles in predicting carcinogenesis, progression and values in clinical management
Abstract
Aberrant expressions of micro-ribonucleic acids (miRs) are closely associated with the pathogenesis in many human cancers. In oesophageal adenocarcinomas, altered expressions of different sets of miRs are noted to be associated with the development of adenocarcinoma from Barrett's oesophagus. In different studies, miRs such as miR-192, miR-196 and miR-21 were frequently noted to up-regulated whereas miR-203, miR-205 and miR-let-7 were commonly down-regulated during the development of Barrett's oesophagus to oesophageal adenocarcinoma. In addition, changes in the expression of miRs are associated with the predication of metastasis, prognosis and response to chemo-radiation in the patients with oesophageal adenocarcinoma. Experimental studies in manipulating the miRs in cancer cell lines could provide hints for therapeutics for the cancer. However, the number of studies reported on these aspects of oesophageal adenocarcinoma was limited and the miRs noted needed to be confirmed by additional studies. Overall, the mechanisms of involvements of miRs in pathogenesis and progression of oesophageal adenocarcinoma are complex. Although miRs have the potential to act as prognostic and clinical biomarkers for cancer therapy in oesophagea...Continue Reading

Astrocytes
Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
Apoptosis
Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
Apoptosis in Cancer
Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
