BACKGROUND: In patients with end-stage heart failure, the primary etiology often originates in the left ventricle, and eventually the contractile function of the right ventricle (RV) also becomes compromised. RV tissue-level deficits in contractile force and/or kinetics need quantification to understand involvement in ischemic and non-ischemic failing human myocardium. METHODS AND RESULTS: The human population suffering from heart failure is diverse, requiring many subjects to be studied in order to perform an adequately powered statistical analysis...

Long non-coding RNAs (lncRNAs) are endogenous molecules longer than 200 nucleotides, and lack coding potential. LncRNAs that interact with microRNAs (miRNAs) are known as a competing endogenous RNAs (ceRNAs) and have the ability to regulate the expression of target genes. The ceRNAs play an important role in the initiation and progression of various cancers. However, until now, there is no a database including a collection of experimentally verified, human ceRNAs. We developed the LncCeRBase database, which encompasses 432 lncRNA-miRNA-mRNA interactions, including 130 lncRNAs, 214 miRNAs and 245 genes from 300 publications...

Aberrant activation of phosphatidylinosito-4,5-bisphosphate 3-kinase/protein kinase B (PI3K/AKT) signaling in cancer has led to pursuit of inhibitors for targeting this pathway. However, inhibitors of PI3K and AKT have failed to yield efficacious results without adverse effects. Here, we screened a library containing 441 authenticated traditional chinese medicine (TCM) plant extracts by examining their effect on cell viability of a human mammary epithelial cell line HMEC-PIK3CAH1047R , which expresses mutant PIK3CAH1047R and has constitutively active AKT signaling...

Granulomatosis polyangiitis (GPA) is an ANCA-related vasculitis (AAV) whose clinical manifestations mainly concern the respiratory tract (upper and lower) and the kidney. The treatment of GPA (as well as other AAV) includes the use of immunosuppressive drugs with numerous side effects; the most frequent complications are infectious and neoplastic. GPA frequently relapses. Epstein Barr Virus (EBV) is a ubiquitous virus; it is estimated that about 90% of the world’s population has BEEN EXPOSED TO with this pathogen and has subsequently developed a latent infection...

N 6 -Methyladenosine (m6 A) is the most frequent post-transcriptional modification in RNA, and it plays a critical role in biological processes. The functions of m6 A remain largely unexplored due to a lack of highly sensitive methods to quantitatively determine the m6 A modification fraction at a precise location. Here, we first reveal that T3 DNA ligase has significant selectivity towards the m6 A modification. On the basis of the new finding, we establish an ultrasensitive quantitation assay for accurately determining m6 A at one-nucleotide resolution in RNA...

High levels of both nitric oxide (NO) and reactive oxygen species (ROS) could act as pro-apoptotic signals in cancerous cells. In this study, we conjugated diazeniumdiolates (NONOates), an important class of NO donors, with a natural occurring plumbagin (PL) which is primarily an excellent ROS inducer. Herein, a total of 12 novel plumbagin/NONOate hybrids have been synthesized and evaluated for their inhibitory effects on a panel of human cancer cell lines (MDA-MB-231, A549, HepG2 and HCT-116 cells) and two normal human cells (HK-2 and WRL-68 cells)...

LncRNAs are regulatory noncoding RNAs that play crucial roles in many biological processes. The dysregulation of lncRNA is thought to be involved in many complex diseases; lncRNAs are often the targets of miRNAs in the indirect regulation of gene expression. Numerous studies have indicated that miRNA-lncRNA interactions are closely related to the occurrence and development of cancers. Thus, it is important to develop an effective method for the identification of cancer-related miRNA-lncRNA interactions. In this study, we compiled 155653 experimentally validated and predicted miRNA-lncRNA associations, which we defined as basic interactions...

Nephropathy is one of the most severe complications of diabetic patients. The therapeutic strategies for diabetic patients should not only focus on the control of blood glucose but also pay attention to the occurrence of diabetic nephropathy (DN). Coenzyme Q10 (CoQ10) has great therapeutic potential for DN. However, the clinical application of CoQ10 has been limited because of its low water-solubility and non-specific distribution. Liposomes were supposed to be an effective way for delivering CoQ10 to kidney...
