Melanoma skin cancer is the fastest growing cancer in the US [1]. A great need exists for improved formulations and mechanisms to prevent and protect human skin from cancers and other skin damage caused by sunlight exposure. Current efforts to prevent UV damage to human skin, which in many cases leads to melanoma and other skin cancers. The primordial melanocortin-1 receptor (MC1R) is involved in regulating skin pigmentation and hair color, which is a natural prevention from UV damage. The endogenous melanocortin agonists induce pigmentation and share a core pharmacophore sequence "His-Phe-Arg-Trp", and it was found that substitution of the Phe by D-Phe results in increasing melanocortin receptor potency...

The voltage-dependent current is a crucial parameter for determining the electrical properties of microelectronic devices. In this study, we aimed to extend a generic dc model to successfully explain the drain current (Id ) for metal-oxide semiconductors (MOSs) and thin-film transistors (TFTs) based on the gate voltage (Vg ), where the threshold voltage (Vth ) could also be obtained from this model in a nature manner. This dc model meets the requirements for compact modeling, including modeling computer circuit simulators...

Little is known about the role of long non-coding RNA XIST in the development of colon cancer. The aim of the present study was to investigate the levels of XIST in colon cancer, and explore its underlying mechanism. In this study, we found XIST expression level was upregulated in colon cancer tissues and cell lines. In addition, the growth rate of cells transfected with si-XIST was significantly decreased compared to that with si-NC, which was reversed by miR-34a targeted with 3'-UTR. Moreover, miR-34a suppressed the expression of WNT1 by binding with the 3'-UTR, which interact with WNT1 to inhibit the proliferation of cells...

Sepsis-induced myocardial dysfunction represents a major cause of death in intensive care units. Alamandine is an important biologically active peptide in the renin-angiotensin system. The present study evaluated whether alamandine improves cardiac dysfunction, inflammation, and apoptosis, and affects the signaling pathways involved in these events. Experiments were carried out in mice treated with lipopolysaccharide (LPS) or alamandine, and in neonatal rat cardiomyocytes. Alamandine increased the ejection fraction and fractional shortening, both of which were decreased upon LPS infusion in mice...

β-site amyloid precursor protein cleaving enzyme 1 (BACE1) is a key enzyme to cleave the amyloid precursor protein to develop Alzheimer's disease (AD). Reducing BACE1 expression in central neuron through RNA interference technology shows great promise to overcome AD. However, to obtain an efficient and neurons-specific delivery of siRNA against BACE1 through systemic administration remains challenging. Here, we design and prepare siRNA nano-carriers based on PEGylated poly(2-(N,N-dimethylamino) ethyl methacrylate) (PEG-PDMAEMA) modified with both the CGN peptide for blood-brain barrier (BBB) penetration and the Tet1 peptide for neuron-specific binding...

Krüppel-like factor 5 (KLF5) is a basic transcription factor that regulates diverse cellular processes during tumor development. Acetylation of KLF5 at lysine 369 (K369) reverses its function from promoting to suppressing cell proliferation and tumor growth. In this study, we examined the regulation of KLF5 by histone deacetylases in the prostate cancer cell line DU 145. While confirming the functions of HDAC1/2 in KLF5 deacetylation and the promotion of cell proliferation, we found that the knockdown of HDAC1/2 upregulated KLF5 protein but not KLF5 mRNA, and the increase in KLF5 protein level by silencing HDAC1/2 was at least in part due to decreased proteasomal degradation...

In this work, we describe a new approach for the characterization of process-related impurities along with an in silico tool to generate orthogonal, integrated downstream purification processes for biological products. A one-time characterization of process-related impurities from product expression in Pichia pastoris was first carried out using linear salt and pH gradients on a library of multimodal, salt-tolerant, and hydrophobic charge induction chromatographic resins. Reversed phase UPLC analysis of the fractions from these gradients was then used to generate large data sets of impurity profiles...

The current study investigated the contribution of phonology to bilingual language control in connected speech. Speech production was elicited by asking Mandarin-English bilinguals to read aloud paragraphs either in Chinese or English, while six words were switched to the other language in each paragraph. The switch words were either cognates or noncognates, and switching difficulty was measured by production of cross-language intrusion errors on the switch words (e.g., mistakenly saying (qiao3-ke4-li4) instead of chocolate)...
