EBV-encoded miRNAs can sensitize nasopharyngeal carcinoma to chemotherapeutic drugs by targeting BRCA1.

Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV)-associated epithelial malignancy. The high expression of BART-miRNAs (miR-BARTs) during latent EBV infection in NPC strongly supports their pathological importance in cancer progression. Recently, we found that several BART-miRNAs work co-operatively to modulate the DNA damage response (DDR) by reducing Ataxia-telangiectasia-mutated (ATM) activity.

EXOSC4 functions as a potential oncogene in development and progression of colorectal cancer.

Colorectal cancer (CRC) is a heterogeneous disease with complex mechanisms of pathogenesis. Classification systems have been proposed based on molecular features of tumors in clinical practice. Thus, more molecular markers associated with development and progression of CRC might serve as useful tools for early diagnosis even for providing more accurate molecular classification.

RASAL2 promotes tumor progression through LATS2/YAP1 axis of hippo signaling pathway in colorectal cancer.

Background: Patients with colorectal cancer (CRC) have a high incidence of regional and distant metastases. Although metastasis is the main cause of CRC-related death, its molecular mechanisms remain largely unknown.

Methods: Using array-CGH and expression microarray analyses, changes in DNA copy number and mRNA expression levels were investigated in human CRC samples.

miR-375 is involved in Hippo pathway by targeting YAP1/TEAD4-CTGF axis in gastric carcinogenesis.

miR-375 is a tumor-suppressive microRNA (miRNA) in gastric cancer (GC). However, its molecular mechanism remains unclear. The aim of this study is to comprehensively investigate how miR-375 is involved in Hippo pathway by targeting multiple oncogenes.

EBV-encoded miRNAs target ATM-mediated response in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is a highly invasive epithelial malignancy that is prevalent in southern China and Southeast Asia. It is consistently associated with latent Epstein-Barr virus (EBV) infection. In NPC, miR-BARTs, the EBV-encoded miRNAs derived from BamH1-A rightward transcripts, are abundantly expressed and contribute to cancer development by targeting various cellular and viral genes.

Downregulation of long non-coding RNA MEG3 in nasopharyngeal carcinoma.

In our previous whole-transcriptome sequencing analysis, downregulation of a long non-coding RNA, maternally expressed gene 3 (MEG3), was identified in NPC samples. This finding suggests the possible role of MEG3 as a tumor suppressor in this distinctive disease. In the present study, two MEG3 variants, AF119863 (MEG3-AF) and BX247998 (MEG3-BX), were found abundantly expressed in a normal nasopharyngeal epithelial cell line, NP69.
