Small Protein Hidden in lncRNA Promotes "Cancerous" RNA Splicing and Tumorigenesis.

Conventional therapies for late-stage colorectal cancer (CRC) have limited effects because of chemoresistance, recurrence, and metastasis. The "hidden" proteins/peptides encoded by long noncoding RNAs (lncRNAs) may be a novel resource bank for therapeutic options for patients with cancer. Here, lncRNA is discovered to encode a small 130-amino acid protein that interacts with several splicing regulators, such as serine- and arginine-rich splicing factor 3 (SRSF3), to regulate mRNA splicing, and the protein thus is named "Splicing Regulatory Small Protein" (SRSP).

Serum microRNA-195 as a potential diagnostic biomarker for breast cancer: a systematic review and meta-analysis.

Serum microRNA-195 (miR-195) expression has been shown to be significantly up-regulated in breast cancer, which implies that it could be a useful biomarker in the early detection of breast cancer. Hence, we performed this meta-analysis to investigate the diagnostic value of miR-195 for breast cancer. Relevant articles were collected from PubMed, Scopus, Embase, the Cochrane Library, BioMed Central, ISI Web of Knowledge, China National Knowledge Infrastructure, Wan Fang Data and Technology of Chongqing databases, from inception to May 24, 2019, by two independent researchers.

Tumor-Specific Drug Release and Reactive Oxygen Species Generation for Cancer Chemo/Chemodynamic Combination Therapy.

The combination of chemotherapeutic drugs and reactive oxygen species (ROS) is a promising strategy to achieve improved anticancer effect. Herein, a nanomedicine (LaCIONPs) that can achieve tumor-specific chemotherapeutic drug release and ROS generation is developed for cancer chemo/chemodynamic combination therapy. The LaCIONPs are constructed by encapsulation of iron oxide nanoparticles (IONPs) and β-lapachone (La) in nanostructure assembled by hydrogen peroxide (HO)-responsive polyprodrug and pH-responsive polymer.

The rs5743708 gene polymorphism in the TLR2 gene contributes to the risk of tuberculosis disease.

Background: It has been reported that one single nucleotide polymorphisms (SNPs) rs5743708 in TLR2 gene might be associated with the susceptibility to tuberculosis disease. Owing to mixed and inconclusive results, we conducted a meta-analysis to systematically summarize and clarify the association between the rs5743708 gene polymorphism in the TLR2 gene and the risk of tuberculosis disease.

Methods: A systematic search of studies on the association of the rs5743708 gene polymorphism in the TLR2 gene with susceptibility to tuberculosis disease was conducted in PubMed.
