Enzymes generally display strict stereospecificity and regioselectivity for their substrates. Here by using FAD-dependent human acetylpolyamine oxidase (APAO), human spermine oxidase (SMOX) and yeast polyamine oxidase (Fms1) we demonstrate that these fundamental properties of the enzymes may be regulated using simple guide molecules, being either covalently attached to polyamines, or used as a supplement to the substrate mixtures. APAO, which naturally metabolize achiral N 1 -acetylated polyamines, displays aldehyde-controllable stereospecificity with chiral 1-methylated polyamines, like (R)- and (S)- 1-methylspermidine (1-MeSpd)...

MiRNA polymorphisms had potential to be biomarkers for hepatocellular cancer (HCC) susceptibility. Recently, miRNA SNPs were reported to be associated with hepatocellular cancer risk, but the results were inconsistent. We performed a systematic review with a meta-analysis for the association of miRNA SNPs with HCC risk. 37 studies were included with a total of 11821 HCC patients and 15359 controls in this meta-analysis. We found hsa-mir-146a rs2910164 was associated with a decreased hepatocellular cancer risk in the recessive model ( P = 0...

Cathepsin S (CTSS) and Sirtuin-1 (SIRT1) played crucial roles in the pathogenesis of chronic obstructive pulmonary disease (COPD). However, the associations between the polymorphisms of CTSS as well as SIRT1 and COPD in Asian population remain elusive. In this study, one SNP in rs12068264 was discovered (in 385 individuals) to be associated with the susceptibility of COPD in a Chinese Han population. The genotyping was performed using improved multiplex ligase detection reaction (iMLDR) technique. Subjects with T allele of rs12068264 in CTSS gene had an increased risk of COPD (T vs C: OR=1...

Chronic wounds are a major complication in patients with cardiovascular diseases. Cell therapies have shown potential to stimulate wound healing, but clinical trials using adult stem cells have been tempered by limited numbers of cells and invasive procurement procedures. Induced pluripotent stem cells (IPSCs) have several advantages of other cell types, for example they can be generated in abundance from patients' somatic cells (autologous) or those from a matched donor. IPSCs can be efficiently differentiated to functional endothelial cells (IPSC-ECs)...

Two coding sequence variants (G1 and G2) of APOL1 gene have been implicated as a higher risk factor for chronic kidney diseases (CKD) in African Americans when compared to European Americans. Previous studies have suggested that the APOL1 G1 and G2 variant proteins are more toxic to kidney cells than the wild type APOL1 G0, but the underlying mechanisms are poorly understood. To determine whether endoplasmic reticulum (ER) stress contributes to podocyte toxicity, we generated human podocytes (HPs) that stably overexpressed APOL1G0, G1, or G2 (Vec/HPs, G0/HPs, G1/HPs, and G2/HPs)...

HIV infection is associated with increased risk of cardio-vascular disease (CVD), even in patients successfully treated with combination anti-retroviral therapy (cART). However, relationship between HIV, cART and pathogenesis of CVD remains controversial. In this study, we evaluated carotid intima media thickness (CIMT), a surrogate marker of atherosclerosis, in HIV-infected subjects receiving or not cART. 109 newly diagnosed HIV-infected subjects and 109 uninfected age-matched controls (all males) without history of CVD, hypertension or diabetes were recruited into this study...

Background: Alzheimer's disease (AD) is the multifactorial neurodegenerative disorder causing progressive memory loss and cognitive impairment. The aberrant accumulation of Amyloid-β (Aβ) and neuroinflammation are two major events in AD. BACE1 is required for the cleavage of amyloid precursor protein (APP) to generate Aβ, which stimulates the nuclear transcription factor κB (NF-κB) signaling, leading to the secretion of inflammatory cytokines. And NF-κB can up-regulate the expression of BACE1. microRNAs (miRNAs) are small non-coding RNAs that regulate gene transcription...

Recurrence is one of the major causes of poor prognosis for patients with hepatocellular carcinoma (HCC), and drug resistance is closely associated with disease recurrence. Histone deacetylase (HDAC) inhibitor scriptaid functions as an anti-cancer agent in many different types of tumors, but its possible roles in HCC progression have not been explored to date. Herein, we show that HDAC inhibitor scriptaid decreases HCC cell proliferation and induces cell cycle G2/M phase arrest in a dose-dependent manner. Furthermore, scriptaid triggered HCC cell death via transcriptional activation of p21 and subsequent elevated global H3Ac levels...

Evolving strategies to counter cancer initiation and progression rely on the identification of novel therapeutic targets that exploit the aberrant genetic changes driving oncogenesis. Several chromatin associated enzymes have been shown to influence post-translational modification on DNA, histones, and non-histone proteins. Any deregulation of this core group of enzymes often leads to cancer development. Ubiquitylation of histone H2B in mammalian cells was identified over three decades ago. An exciting really interesting new gene (RING) family of E3 ubiquitin ligases, known as RNF20 and RNF40, monoubiquitinates histone H2A at K119 or H2B at K120 and is known to function in transcription elongation, DNA double strand break repair processes, maintenance of chromatin differentiation, and exerting tumor suppressor activity...

Urinary bladder cancer (UBC) is one of the most common malignancies worldwide. UBC patients at muscle invasive stage have poor clinical outcome, due to high propensity for metastasis. Non-tumor activated fibroblasts, named α-SMA+Fs, is similar to carcinoma-associated fibroblasts (CAFs) which could express α-SMA. However, whether α-SMA+Fs patients could induce UBC cell invasion is unclear. Herein, we found that characterization of primary α-SMA+Fs separated from PBOO (partial bladder outlet obstruction) rats was fell in between normal fibroblasts (α-SMA-Fs) and CAFs...

During the study of host-parasite relationships in Taeniid parasite diseases, including cysticercosis and hydatidosis, reports have described the presence of host proteins in the cyst fluid and tissue of metacestodes. However, the fate or role of host elements inside the parasite remains barely explored. After the publication of genomes of four cestode species, it became clear that these organisms possess a limited biosynthetic capability. The initial goal of this study was to determine if uptaken host proteins could be a source of essential amino acids for cysticerci...
