The invention discloses novel application of a human YTHDF1 (Youth-Tech-Health Domain Family Member 1)
gene, that is, a human YTHDF1
gene expression amount detection
reagent is applied to preparationof
lung cancer clinical diagnosis reagents, a human YTHDF1
gene is applied to preparation of
lung cancer medicines, compared with normal pulmonary epithelial cells, the YTHDF1 gene is highly expressed in
lung cancer cells,
RNA (Ribonucleic Acid) designed according to the YTHDF1 gene is capable of interfering slow viruses, inhibiting expression of YTHDF1, remarkably inhibiting proliferation of thelung cancer cells, retarding tumor
cell division at a G0 / G1 phase and promoting
cell apoptosis, inhibiting formation of
nude mouse transplanted tumour, and furthermore the purpose of treating
lung cancer can be achieved; YTHDF1
gene knockout mouse tumor formation capability detection shows that
cell proliferation is remarkably inhibited, and cell
apoptosis is remarkably increased; the results show that the YTHDF1 gene can be used as a target for
lung cancer treatment, and wide prospects are provided for development of
lung cancer treatment medicines based on YTHDF1 genes in future.
