Kinases are downstream modulators and effectors of various cell signaling cascades and play key roles in the development of neoplastic diseases. The objective of this study was to evaluate the expression of genes and proteins of the SRC family, including FYN, YES, BLK, FGR, LYN and SRC, in a model of intestinal gastric carcinogenesis generated by treating Cebus apella, a New World non-human primate, with N-methyl nitrosourea (MNU). Materials and Methods: mRNA expression of genes was measured by real-time reverse transcription quantitative PCR (RT-qPCR) and protein expression was measured by western blotting in six Cebus apella treated with N-methyl-nitrosourea (MNU) for about 2.5 years. Results: Elevated mRNA and protein expression mainly of the SRC and LYN kinases was observed. Their expression was gradually increasing as non-atrophic gastritis was evolving to gastric cancer. Conclusion: SRC family kinases play a key role in tumor progression and metastasis and may be a promising target for the treatment of gastric cancer. ER -
