Hepatocellular carcinoma deletion gene 1 (DLC-1) was first identified in a chromosomal study of various hepatocellular carcinoma cell lines, and was named after its low expression in genomic chromosome segments. DLC-1 is an important oncogene and has been found to play an important role in the development of many tumors, and is expressed in many organs and tissues such as the heart, lung, brain, liver, breast, prostate, etc. DLC1 function may be related to liver cancer, prostate cancer, breast cancer, lung cancer, multiple myeloma, etc., and can inhibit the proliferation and migration of cancer cells. Deletion or down-regulation of DLC1 function may cause cancer cell development, distant metastasis and secondary damage, but the exact mechanism is unclear. The study of DLC-1 may provide an important indicator for early detection, early diagnosis, early treatment and prognosis of tumors, and may provide an objective basis for the effectiveness of tumor treatment. If you feel unwell, it is recommended to consult a doctor in time and take standardized treatment under the guidance of a professional doctor.
