BACKGROUND Approximately 2-10% of the patients with hepatolithiasis may develop cholangiocarcinoma (CCA). Despite recent advances in the treatment of cancers, the 5-year survival rate for CCA patients currently remains poor, primarily due to early local invasion and distant metastasis of the cancer. This study aimed to investigate miR-200a expression in combined hepatolithiasis and CCA as well ...

BACKGROUND/AIMS Long non-coding RNAs (lncRNAs) have been reported to play pivotal roles in multiple tumors and can act as tumor biomarkers. In this study, we explored the association of the expression of an lncRNA, DGCR5 with clinicopathological features and prognosis in HCC. METHODS Expression levels of DGCR5 were detected by quantitative real-time PCR (qRT-PCR) and the clinical data was obt...

BACKGROUND Anorectal melanoma is one of the rare but significant malignancies of the anorectal area. This malignancy currently accounts for 1% of all types of melanoma and less than 1% of all the anorectal area malignancies. Very rare cases of this disease have been reported worldwide.Anorectal melanoma is mostly diagnosed while treating other benign conditions of this area such as hemorrhoids ...

micrornas (miRNAs) play an important role in a wide range of physiological and developmental processes by negatively regulating the expression of target genes at the post-transcriptional level. In this study, we investigated the differential miRNA expression signature between gastric cancer cells and normal gastric mucosa to determine changes in m...

The therapeutic landscape of lung cancer has evolved tremendously over the past 10 years with the discovery of oncogenic drivers constitutively activated by mutation, translocation or fusion. An activating EGFR mutation or ALK rearrangement is present in around 15% of Caucasian patients with non-small cell lung cancer (NSCLC), with targeted therapy constituting the basis of upfront treatment fo...

BACKGROUND The objective of this study is to detect HMGA2 expression in renal carcinoma to explore its relationship with clinicopathology and its significance in prognosis. METHODS Expressions of HMGA2 mRNA and protein were detected in 50 renal carcinoma specimens, 50 corresponding adjacent normal kidney tissue samples and 40 renal benign tumour specimens via reverse transcription polymerase ...

Like other cancer types, breast cancer is considered to be a genetic disease. While the majority of genetic changes are somatic, a minority are in germline. About 10-20% of breast cancer is thought to be due to a germline mutation in high-penetrance genes, where the major focus has been on BRCA1 and BRCA2. Some of these mutations are defined as founder mutations. Studies on founder mutations yi...
