The invention discloses application of a reagent capable of promoting circular RNA (Ribonucleic Acid) circRNF13 expression to preparation of a medicine for treating tongue squamous cell carcinoma. A research proves that circRNF13 is overexpressed in tongue squamous cell carcinoma cells and the proliferation of the tongue squamous cell carcinoma cells can be inhibited. Therefore, a circRNF13 overexpression preparation is used for treating the tongue squamous cell carcinoma and has profound clinical significance and an important popularization and application prospect.

The invention discloses a Chinese medicinal compound with a tongue squamous cell carcinoma resisting effect and a preparation method thereof. The Chinese medicinal compound is prepared from the following raw materials in parts by weight: 10-20 parts of waxgourd seed, 12-24 parts of rhizoma pinellinae praeparata, 10-20 parts of arisaema cum bile, 12-24 parts of indian iphigenia bulb, 10-20 parts of ternate buttercup root, 10-20 parts of wild buckwheat rhizome, 10-20 parts of heartleaf houttuynia herb, 15-30 parts of hairyvein agrimonia herb and bud, 12-24 parts of sappan wood, 15-30 parts of safflower, 10-20 parts of straight ladybell root, 10-20 parts of fragrant solomonseal rhizome and 10-20 parts of dwarf lilyturf root. The Chinese medicinal compound with the tongue squamous cell carcinoma resisting effect provided by the invention is prepared by selecting raw materials according to the traditional Chinese medicine theory and the pathogenesis of tongue squamous cell carcinoma, and components are blended scientifically and reasonably; and as proved by a pharmacodynamics experiment result, the Chinese medicinal compound can contribute to remarkably lowering the content of PGE2, has a very good tongue squamous cell carcinoma resisting effect, is free from untoward effects after long-term use, and can be developed into a new generation of tongue squamous cell carcinoma resisting medicament.

The invention discloses applications of C6orf58 gene as an early stage diagnosis molecular marker of tongue squamous carcinoma. It is confirmed by experiments that: compared with normal mucous tissue, C6orf58 gene expression level of tongue squamous carcinoma tissue is increased obviously; and it is confirmed by RNA interface experiment that C6orf58 is capable of influencing proliferation of tongue squamous carcinoma cells. Drugs used for inhibiting C6orf58 gene expression can be developed based on the invention so as to realize clinical prevention and treatment of tongue squamous carcinoma.

The invention provides a novel target gene for diagnosing and treating tongue squamous carcinoma and application thereof and particularly relates to application of a KLK14 gene and an expression product thereof to diagnosis and treatment of tongue squamous carcinoma. To research the occurrence and development mechanisms of tongue squamous carcinoma, search for an effective molecular target gene for diagnosing and treating tongue squamous carcinoma, promote early diagnosis, prevention and treatment of the disease and lower the death rate of tongue cancer, firstly, RNA-seq sequencing is utilized to detect differential expression genes of tongue squamous carcinoma, cancer branch and normal oral mucosa; secondly, a Real-time PCR technology is utilized to verify the sequencing result; then, an interference technology is utilized, and expression of the candidate gene KLK14 in tongue squamous carcinoma cells SCC15 is silenced. By means of the novel target gene for diagnosing and treating tongue squamous carcinoma and application thereof, an experimental foundation is laid for clinical application of the KLK14 gene to tongue squamous carcinoma, and a new target gene and theoretical basis are provided for early diagnosis and treatment of tongue squamous carcinoma.

The invention discloses a shRNA, a lentiviral vector and its construction method and application for inhibiting the expression of human EDARADD gene. Firstly, the forward strand and the reverse strand of the DNA oligo aiming at the RNA interference target sequence are synthesized; the forward strand and the reverse strand are annealed to form a band Double-stranded DNA at the cohesive end; linearize the lentiviral vector by enzyme digestion, connect the linearized vector to the double-stranded DNA; transform the ligated product into E. coli competent cells, and perform PCR identification on the positive clones obtained; plasmid extraction, For the next step of virus packaging. The present invention uses the EDARADD gene as a template to design the RNA interference target sequence, designs the shRNA interference sequence according to the selected target sequence, packages and constructs the RNA interference lentiviral vector, and knocks down the EDARADD gene, which will significantly affect the CAL of tongue squamous cell carcinoma cells Proliferation of ‑27 cells, affecting cell clone formation ability, and promoting cell apoptosis.
