HAPLN3 inhibits apoptosis and promotes EMT of clear cell renal cell carcinoma via ERK and Bcl-2 signal pathways.

Hyaluronan and proteoglycan link protein 3 (HAPLN3) is a member of the hyaluronan and proteoglycan link protein family expressed in the extracellular matrix closely associated with the development and occurrence of various malignant tumors; yet, its function in clear cell renal cell cancer (ccRCC) is still poorly understood. The following study investigated the progress and mechanism of HAPLN3 on ccRCC using bioinformatics analysis and in vitro experiments. In order to determine whether HAPLN3 is differentially expressed in ccRCC, we analyzed data from the Cancer Genome Atlas (TCGA) and GSE40435 and further validated them in the Human Protein Atlas (HPA) database.

miR-1307-5p suppresses proliferation and tumorigenesis of bladder cancer via targeting MDM4 and the Hippo signaling pathway.

Background: Emerging evidence has shown that miR-1307-5p is involved in tumorigenesis of various types of cancer. This study aims to assess the role and mechanism of miR-1307-5p in bladder cancer.

Methods: Bioinformatics analyses were carried out with clinical datasets in the public domains.

Celecoxib Synergistically Enhances MLN4924-Induced Cytotoxicity and EMT Inhibition Via AKT and ERK Pathways in Human Urothelial Carcinoma.

MLN4924 is a specific small-molecule inhibitor of NEDD8-activating enzyme (NAE) that blocks the neddylation modification cascade. Several I/II/III clinical trials suggested that MLN4924 exerts an antitumor effect against various malignancies. However, recent studies have also found that MLN4924 activates the PI3K/AKT and MAPK/ERK signal pathways, important regulators of tumorigenesis, and drug resistance in human urothelial carcinoma (UC).

LncRNA GAS5 participates in the regulation of dexamethasone on androgen receptor -negative and -positive prostate cancer cell proliferation.

Background: Androgen receptor (AR) and long non-coding RNAs (lncRNA) play important roles in the initiation and progression of prostate cancer (PCa). The present study was designed to investigate whether lncRNA growth arrest-specific 5 (GAS5) is involved in the regulation of dexamethasone on the proliferation of AR PCa and AR PCa cell lines.

Methods: Cell proliferation and cell cycle distribution were assessed using MTT assay and flow cytometry, respectively.
