Wild-type IDH1 Knockout Leads to G0/G1 Arrest, Impairs Cancer Cell Proliferation, Altering Glycolysis, and the TCA Cycle in Colon Cancer.

The isocitrate dehydrogenase (IDH), which participates in the TCA cycle, is an important key enzyme in regulating cell metabolism. The effect of the metabolic IDH enzyme on cancer pathogenesis has recently been shown in different types of cancer. However, the role of wild-type (wt) IDH1 in the development of colon cancer is still unknown.

The elevated D-2-hydroxyglutarate level found as a characteristic metabolic change of colon cancer in both in vitro and in vivo models.

The D-2-hydroxyglutarate (D-2-HG), whose normal cellular concentration is low, can be accumulated 10-100 times natural levels in some cancer types and participates in the carcinogenesis process. D-2-HG is produced by different pathways specific to cancer type. In this study, the level of significant metabolites produced in some metabolic pathways related to D-2-HG in the energy metabolism was determined in colon adenocarcinoma cell lines at different stages.

Synthesis and characterization of thiosemicarbazone-functionalized organoruthenium (II)-arene complexes: Investigation of antitumor characteristics in colorectal cancer cell lines.

In the current study, organoruthenium(II)-arene complexes (I-IV) have been prepared by the reaction of [{(η-p-cym)RuCl}(μ-Cl)] with new thiosemicarbazones (TSC1-4).The isolate was analyzed using elemental analysis, FT-IR, H and C NMR spectroscopy and single-crystal XRD. Subsequently, the complexes and TSC ligands were assessed for anticancer properties in vitro against three different colorectal cancer stage's cell lines (Caco-2, DLD-1, and SW620) and a noncancerous cell line (CCD18Co).
