Activating Compound

Activating Compound Comment Organism Structure
additional information ChoKalpha mRNA levels are increased in tumour cell lines in terms of their corresponding normal human primary BEC. ChoKalpha is overexpressed with a consequent increase in phosphorylcholine production in lung-cancer cells. Homo sapiens

Application

Application Comment Organism
diagnostics choline kinase alpha expression is a new prognostic factor that could be used to help identify patients with earlystage non-small-cell lung cancer who might be at high risk of recurrence, and to identify patients with favourable prognosis who could receive less aggressive treatment options or avoid adjuvant systemic treatment.

lung cancer tissue, frozen tissue samples are homogenised and lysed in buffer that contained 1.5 mmol/l magnesium chloride, 0.2 mmol/l EDTA, 0.3 M sodium chloride, 25 mmol/l HEPES at pH 7.5, 20 mmol/l beta-glycerophosphate, and 0.1% Triton X-100. Cells are lysed in ice-cold lysis buffer. Nuclei and detergent-insoluble material are removed by centrifugation. Homo sapiens
