Differential transcriptome analysis in HPV-positive and HPV-negative cervical cancer cells through CRISPR knockout of miR-214.

In this study we have investigated the effects of a tumour suppressor microRNA, miR-214, on gene expression in HPV-positive (CaSki) and HPV-negative cervical cancer cells (C33A) by RNA sequencing using next generation sequencing. The HPV-positive and HPV-negative cervical cancer cells were either miR-214- knocked-out or miR-214-overexpressed. Gene expression analysis showed that a total of 904 genes were upregulated and 365 genes were downregulated between HPV-positive and HPV-negative cervical cancer cells with a fold change of +/- 2.

CAR T cell therapy: A new era for cancer treatment (Review).

Cancer has recently been identified as the leading cause of mortality worldwide. Several conventional treatments and cytotoxic immunotherapies have been developed and made available to the market. Considering the complex behavior of tumors and the involvement of numerous genetic and cellular factors involved in tumorigenesis and metastasis, there is a need to develop a promising immunotherapy that targets tumors at both the cellular and genetic levels.

Modulation of DNA methylation by human papillomavirus E6 and E7 oncoproteins in cervical cancer.

Human papillomaviruses (HPVs) are double stranded circular DNA viruses that infect cutaneous and mucosal epithelial cells. Almost 99% of cervical cancer has a HPV infection. The early oncoproteins E6 and E7 are important in this cellular transformation process.

Transcriptomic analyses of genes differentially expressed by high-risk and low-risk human papilloma virus E6 oncoproteins.

Human papilloma virus is the causative agent for cervical cancer with 99 % of cervical cancer cases containing HPV. The high risk HPV-16, 18 and 31 are the major causative agents. The low risk HPV-6, 11 have been reported to cause penile, laryngeal, bronchogenic and oesophageal cancer.
