The reversible
phosphorylation plays an important regulatory
role in various pathological and
physiological processes. Src Homology 2 domain containing
protein tyrosine phosphatase (SHP2),a featured member of the
protein tyrosine phosphatase family,is identified as the first PTP
proto-oncogene. SHP2 is associated with
breast cancer,
leukemia,
lung cancer,
liver cancer,
gastric cancer,
laryngeal cancer,
oral cancer and other types of
cancer. Signalling pathways involving SHP2 have also been discovered. It has been recently reported that the high expression of SHP2 in
lung cancer regulates
cancer cell proliferation,
metastasis and
drug resistance. SHP2 may be a potential thera?peutic target because it is implicated in many
diseases. This article focuses on the
research progress in functions of SHP2 in
lung cancer.
