Identification and Analysis of Long Non-Coding RNAs Related to UV-B-Induced Anthocyanin Biosynthesis During Blood-Fleshed Peach () Ripening.

Blood flesh is a key fruit trait in peaches () and can be attributed to the accumulation of anthocyanins. The roles of long non-coding RNAs (lncRNAs) have been highlighted by multiple studies in regulating fruit ripening, anthocyanin accumulation, and abiotic stress responses in many flowering plants. Such regulatory functions of lncRNAs in Prunus persica, nonetheless, have not been reported.

Role of miR-486-5p in regulating renal cell carcinoma cell proliferation and apoptosis via TGF-β-activated kinase 1.

Renal cell carcinoma (RCC) is a common kidney tumor in adults. The role of miR-486-5p in RCC is unknown. The aim of our study was to identify new targets regulated by miR-486-5p in RCC, to obtain a deeper insight into the network and to better understand the role of these microRNAs and their targets in carcinogenesis of RCC.

Long intergenic non-coding RNA 00152 promotes renal cell carcinoma progression by epigenetically suppressing P16 and negatively regulates miR-205.

Long non-coding RNAs (lncRNAs) have been reported to play important roles in the tumorigenesis and development of several human cancers. Long intergenic non-coding RNA 152 (LINC00152) is significantly up-regulated in some solid tumors. However, the role of LINC00152 in the pathogenesis and development of renal cell carcinoma (RCC) remains largely unclear.

IL-6 is involved in malignancy and doxorubicin sensitivity of renal carcinoma cells.

Various survival factors such as the pleiotropic cytokine interleukin-6 (IL-6), a major mediator of inflammation and activator of signal transducer and activator of transcription 3 (STAT3), serve to block apoptosis in cancer cells. Our present study revealed that the expression of IL-6, while not other IL-2, IL-4, IL-8, or IL-10, was significantly elevated in resistance of renal carcinoma cells (RCC) when compared with human renal proximal tubule epithelial cell line HK-2. The inhibition of IL-6 by siRNA can suppress the proliferation, migration and invasion of RCC cells and increase the doxorubicin (Dox) sensitivity.

Role of Protease-Activated Receptor 2 in Regulating Focal Segmental Glomerulosclerosis.

Unlabelled: Background /Aims: The underlying mechanisms leading to focal segmental glomerulosclerosis (FSGS) are lacking. In this report, we examined the role of protease-activated receptors (PARs) subtype PAR2 and its downstream signals in regulating the pathophysiological process of FSGS.

Methods: Nephropathy was induced by intravenous injections of adriamycin (ADR) in rats to study FSGS.

Long non-coding RNA CCAT2 promotes gastric cancer proliferation and invasion by regulating the E-cadherin and LATS2.

Dysregulation of long non-coding RNAs (lncRNAs) play important roles in tumor development and progression. The long non-coding RNA CCAT2 has been identified to be up-regulated in gastric cancer (GC). However, the detailed molecular mechanism of CCAT2 involved in GC progression is still unknown.

Synthesis and biological evaluation of 3-(4-fluorophenyl)-1H-pyrazole derivatives as androgen receptor antagonists.

A novel series of 3-(4-fluorophenyl)-1H-pyrazole derivatives were synthesized and evaluated for their antiproliferative activity against two prostate cancer cell lines (LNCaP and PC-3) and androgen receptor target gene prostate-specific antigen (PSA) inhibitory activity in LNCaP cells. Several compounds showed potent antiproliferative activity against LNCaP cells and showed a promising PSA downregulation rate. Among these, compound 10e selectively inhibited LNCaP cell growth with an IC50 value of 18 μmol/l and showed a PSA downregulation rate of 46%, which was better than the lead compound T3.

Design, Synthesis and Biological Evaluation of Thiohydantoin Derivatives as Novel Anti-prostate Cancer Agents.

A series of novel thiohydantoin derivatives were synthesized and evaluated for the abilities of inhibiting cell proliferation and prostate specific antigen (PSA) expression in prostate cancer cells. These derivatives selectively inhibited proliferation of AR positive LNCaP cells and PSA expression except compounds 5i and 5j. Compound 5t was approximately 15-fold more potent than MDV3100 to inhibit LNCaP cell proliferation.

Discovery of novel androgen receptor antagonists: a hybrid approach of pharmacophore-based and docking-based virtual screening.

Androgen receptor (AR) is an attractive target for the treatment of prostate cancer. An integrated pharmacophore-based and docking-based virtual screening approach was applied to identify novel AR antagonists with a distinct scaffold. The candidate compounds were evaluated for their abilities to inhibit prostate cancer cell proliferation and AR target gene prostate-specific antigen gene expression as well as the binding affinity to AR.

Synthesis and biological evaluation of novel indoline-2,3-dione derivatives as antitumor agents.

A new series of 1,5-disubstituted indolin-2,3-diones was synthesized and their inhibition of the growth of a human acute promyelocytic leukemia (HL-60) cell line was evaluated. These compounds had promising inhibition of HL-60 cell growth in vitro. Results indicated that compounds with a benzyl substituent at the N-1 position on the indolin-2,3-dione ring had more potent antiproliferative activity than those with a (4-fluorobenzyl) amino-2-oxoethyl substituent at the N-1 position.
