Materials and Methods: 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). Results: 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. Conclusion: 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.
