To evaluate the expression of lincRNA-p21, H19, EMX2OS, SNHG12 and MALAT1 in a mouse model of human papillomavirus 16 (HPV16)-induced carcinogenesis and cachexia.
Chest skin, ear, tongue, penis and gastrocnemius muscle samples from wild-type mice (HPV-) and K14-HPV16 male mice (HPV+) were collected to evaluate the expression of the selected lncRNAs using real-time PCR (qPCR).
In chest skin and ear, H19, SNHG12, EMX2OS and lincRNA-p21 were down-regulated in HPV+ versus HPV- mice. In tongue and penile tissues, there was only down-regulation of lincRNA-p21 in HPV+ mice. Additionally, in penile tissue, lincRNA-p21 expression decreased in HPV-induced lesions comparing with normal tissues. In gastrocnemius muscle, MALAT1 was up-regulated and lincRNA-p21 was down-regulated in HPV+ versus HPV-mice.
H19, SNHG12, EMX2OS and lincRNA-p21 may be involved in HPV-induced carcinogenesis. In addition, MALAT1 and lincRNA-p21 may play a role in muscle wasting and contribute to cancer cachexia.
评估长链非编码 RNA(lncRNA)-p21、H19、EMX2OS、SNHG12 和 MALAT1 在人乳头瘤病毒 16(HPV16)诱导的致癌作用和恶病质的小鼠模型中的表达。
采集野生型小鼠(HPV-)和 K14-HPV16 雄性小鼠(HPV+)的胸皮、耳、舌、阴茎和腓肠肌样本,采用实时 PCR(qPCR)评估所选 lncRNA 的表达。
在胸皮和耳部,HPV+小鼠中 H19、SNHG12、EMX2OS 和 lincRNA-p21 的表达下调。在舌和阴茎组织中,仅在 HPV+小鼠中下调了 lincRNA-p21。此外,在阴茎组织中,与正常组织相比,HPV 诱导的病变中 lincRNA-p21 的表达降低。在腓肠肌中,HPV+小鼠中 MALAT1 上调,lincRNA-p21 下调。
H19、SNHG12、EMX2OS 和 lincRNA-p21 可能参与 HPV 诱导的致癌作用。此外,MALAT1 和 lincRNA-p21 可能在肌肉消耗中发挥作用,并导致癌症恶病质。
