Expression of E7 mRNA HPV in laryngeal carcinoma tissue and its relationship with the growth of laryngeal carcinoma cells / 中国医师杂志

ABSTRACT

Objective To observe the expression of apoptosis and invasion genes in different tissues of laryngeal lesions,and to detect the content of proliferation related protein and proliferation inhibition gene.Methods In our hospital,the clinical diagnosis of laryngeal carcinoma,precancerous lesions and vocal polyps in 88 cases of laryngeal carcinoma,surgical excision of lesion specimens cut from the amount of Pro apoptotic genes and promote invasion and proliferation related protein,gene the content of tissue proliferation inhibition gene detection.Results The laryngeal carcinoma group of Pro apoptotic genes nicotinamide adenine dinucleotide phosphate oxidase 1 (NOX1) and large tumor suppressor gene 1 (LATS1) were all significantly lower than lesion group and polyp group (P ＜ 0.05).Laryngeal carcinoma invasion promoting gene tumour necrosis factor receptor associated factor 6 (TRAF6),and cellular FADD-like interleukin1βconverting enzyme inhibitory protein (c-FLIP) content were significantly higher than that of laryngeal pre cancerous lesions and vocal polyps (P ＜ 0.05).The proliferation related protein Cyclin-dependent kinase 6 (CDK6) and E2F1 in laryngeal carcinoma were significantly lower than that in the lesion and polyp group,and cyclin D1 (CCND1),Bmi-1,and Livin contents were significantly higher than that in the lesion group and the polyp group (P ＜ 0.05).The levels of differentiated embryo-chondrocyte expressed gene 1 (DEC-1),IκB kinase 16(IKK16),large tumor suppressor gene 1 (LAST-1),receptor-interacting proteins-1-(RIP-1),and c-myc promoter binding protein-1 (MBP-1) in the tissue of laryngeal carcinoma were significantly lower than those in the lesion group and polyp group (P ＜ 0.05).Conclusions The laryngeal carcinoma invasion promoting gene was higher than that in other tissues,inhibition of gene content was lower than that of other tissues proliferation related protein gene,apoptosis and proliferation,apoptosis and invasion of lesions in gene expression level,proliferation related protein and proliferation inhibition of gene content and laryngeal squamous cell carcinoma were related to laryngeal disease prevention significance of detection.
