Phuong-Hien reported that LYN kinase in the tumor microenvironment exerts an important function in tumor progression of various cancers types.[36] Similarly, a previous study reported that the molecular role of LYN in the control of immunoreceptors can switch to direct homeostasis or inflammation.[37] LCK is an important molecule regulating the functions of T-cells. The gene discussed is LYN; the disease is cancer.
