The study aimed to screen mutation of human homeostatic iron regulator (HFE) in colorectal carcinoma (CRC) and detect their associations with clinicopathological parameters. Expression of HFE was determined by quantitative polymerase chain reaction in matched CRC and non neoplastic colorectal mucosal tissue of 76 patients. Genomic DNA extracted were subjected to high high-resolution melt curve analysis and Sanger sequencing to detect mutations in HFE.

Purpose: Heme is a crucial compound for cell survival but is also equipped with the potential to be toxic and carcinogenic to cells. However, with the recent advancement of knowledge regarding ferroptosis, the iron mediated cell death, heme can be postulated to induce tumour suppression through ferroptosis. This review summarizes the literature on the carcinogenic and anticarcinogenic properties of heme with specific emphasis on the alterations observed on heme synthesis, metabolism and transport in tumour cells.

Esophageal adenocarcinoma is heterogeneous and studies have reviewed many important mutations that contribute to the pathogenesis of the cancer. These discoveries have helped paved the way into identifying new gene markers or gene targets to develop novel molecular directed therapy for better patient outcomes in esophageal adenocarcinoma. Despite the recent bloom in next-generation sequencing, Sanger sequencing still represents the gold standard method for the study of the driver genes in esophageal adenocarcinoma.

Somatic copy-number alterations are commonly found in cancer and play key roles in activating oncogenes and deactivating tumor suppressor genes. Digital polymerase chain reaction is an effective way to detect the changes in copy number. In esophageal adenocarcinoma, detection of somatic copy-number alterations could predict the prognosis of patients as well as the response to therapy.
