Two new constituents from the aerial parts of Salvia miltiorrhiza Bge.

Two new constituents: a neolignan, salignan A (1) and a phenolic acid, salside A (2), along with two known compounds (3, 4) have been isolated from the aerial parts of Salvia miltiorrhiza Bge. All structures were assigned on the basis of detailed spectroscopic analyses. The absolute configuration of 1 was characterised by electronic circular dichroism (ECD) spectroscopy. Compounds 1 and 3 exhibited moderate inhibitory effects on nitric oxide (NO) production in LPS-induced RAW264.7 cells, and the IC50 values are 11.58 and 10.73 µM, respectively. Compound 4 displayed moderate antioxidant activity to scavenge DPPH and ABTS radicals, and the IC50 values are 7.96 and 1.10 µM, respectively.

Long Non-coding RNA EBLN3P Regulates UHMK1 Expression by Sponging miR-323a-3p and Promotes Colorectal Cancer Progression.

Background: Growing studies have demonstrated that long non-coding RNA (lncRNA) can act as crucial roles during the progression of various tumors, including colorectal carcinoma (CRC). We aimed to determine lncRNA endogenous bornavirus-like nucleoprotein (EBLN3P) expression in CRC and examine its influence on tumor behaviors of CRC cells. Materials and Methods: Quantitative real-time polymerase chain reaction was used to determine the expression levels of EBLN3P and miR-323a-3p in CRC tissues and cell lines. Cell viability, migration, invasion, and apoptosis were assessed by Cell Counting Kit 8, colony formation, Transwell assay, wound healing assays, and flow cytometry. Bioinformatics and dual-luciferase assays were used to investigate the interaction between EBLN3P and miR-323a-3p, as well as between miR-323a-3p and U2AF homology motif kinase 1 (UHMK1). Western blot was applied for detecting the expressions of the related proteins. Results: EBLN3P was highly expressed in CRC, and its high expression was distinctly associated with increased tumor size, histology/differentiation and advanced TNM stage, and poor clinical outcome of CRC patients. EBLN3P silencing significantly inhibited the proliferation and metastasis and induced the apoptosis of CRC cells. Mechanistically, overexpression of EBLN3P exhibited tumorigenic effects through downregulating the inhibitory effects of miR-323a-3p on UHMK1 expression. The correlation analysis confirmed the positive or negative association among EBLN3P, miR-323a-3p, and UHMK1. Conclusion: EBLN3P promoted the development of CRC via targeting miR-323a-3p/UHMK1, which provided a new idea for treating CRC.
