Repulsive guidance molecules b (RGMb): molecular mechanism, function and role in diseases.

Repulsive guidance molecule b (RGMb), a glycosylphosphatidylinositol-anchored member of the RGM family, is initially identified as a co-receptor of bone morphogenetic protein (BMP) in the nervous system. The expression of RGMb is transcriptionally regulated by dorsal root ganglion 11 (DRG11), which is a transcription factor expressed in embryonic DRG and dorsal horn neurons and plays an important role in the development of sensory circuits. RGMb is involved in important physiological processes such as embryonic development, immune response, intercellular adhesion and tumorigenesis.

Fluorescence lifetime imaging of human pancreatic lipase activity using a novel probe for early diagnosis of severe acute pancreatitis.

Severe Acute Pancreatitis, a serious condition caused by factors such as gallstones and chronic excessive alcohol consumption, with a very high mortality rate. Human pancreatic lipase (hPL) is a key digestive enzyme and abnormal activity levels of this enzyme are important indicators for diagnosing and monitoring pancreatic diseases. A fluorescent probe, LPP, has been developed to monitor the activity of hPL, especially in cases of SAP.

LINC MIR503HG Controls SC-β Cell Differentiation and Insulin Production by Targeting CDH1 and HES1.

Stem cell-derived pancreatic progenitors (SC-PPs), as an unlimited source of SC-derived β (SC-β) cells, offers a robust tool for diabetes treatment in stem cell-based transplantation, disease modeling, and drug screening. Whereas, PDX1/NKX6.1 PPs enhances the subsequent endocrine lineage specification and gives rise to glucose-responsive SC-β cells in vivo and in vitro.

A novel fluorescent probe for the detection of peroxynitrite and its application in mice epileptic brain model.

Herein, a fluorescent probe, GYP, was developed for the detection of ONOO in KA-induced epileptic brains. In solution, as a ratiometric probe, GYP indicated practical properties including steadiness under wide pH range (3.0-12.

High GNG13 expression is associated with poor survival in epithelial ovarian cancer and breast cancer.

Recently, change in the GNG13 expression has been shown to result in multiple congenital malformations and sexual reversal, and it was also found in the brain. The aim of this study was to measure the expression levels in epithelial ovarian cancer (EOC) and breast cancer (BC) and assess their value as a potential prognostic marker. The correlation of GNG13 protein expression was detected by immunohistochemistry (IHC) in 119 EOC and 125 BC tissues.

miR-573 suppresses pancreatic cancer cell proliferation, migration, and invasion through targeting TSPAN1.

Purpose: To explore whether miR-573 can suppress pancreatic cancer cell proliferation, migration, and invasion by targeting TSPAN1.

Methods: The expression of miR-573 and TSPAN1 in pancreatic cancer tissues and cells lines was analyzed using RT-qPCR. The human pancreatic cancer cell line PANC‑1 was transfected with miR-573 mimic, pcDNA3.

HAX-1 overexpression in gastric cancer promotes cell proliferation.

Background: HAX-1 is involved in the regulation of cellular processes such as apoptosis, proliferation and migration and is closely related to tumorigenesis and tumor metastasis. However, expression of HAX-1 in gastric cancer and its role in tumor development and progression remain unclear.

Methods: Quantitative polymerase chain reaction was used to detect the expression of HAX-1 mRNA in gastric cancer tissues and adjacent non-tumorous tissues.

Using GRGDSPC peptides to improve re-endothelialization of decellularized pancreatic scaffolds.

Engineering of functional vascularized pancreatic tissues offers an alternative way to solve the perpetual shortage of organs for transplantation. However, revascularization remains a major bottleneck in biological engineering, which limited the further clinical applications of this strategy. In this study, an efficient approach for enhancing re-endothelialization of rat decellularized pancreatic scaffolds (DPS) was presented, by conjugating with GRGDSPC peptide to maximize coverage of the vessel walls with human umbilical vein endothelial cells (HUVECs).

UV photodetectors based on 3D periodic Au-decorated nanocone ZnO films.

Thermal nanoimprinting technology was employed to fabricate 3D periodic nanocone ZnO films with different height/pitch values for photodetectors to optimize their light capturing property. The photocurrents of patterned film photodetectors increase with the height/pitch values. The patterned ZnO-Au hybrid film further boosts the ultraviolet (UV) response.

Enhanced photoelectrocatalytic performance of α-Fe2O3 thin films by surface plasmon resonance of Au nanoparticles coupled with surface passivation by atom layer deposition of Al2O3.

The short lifetime of photogenerated charge carriers of hematite (α-Fe2O3) thin films strongly hindered the PEC performances. Herein, α-Fe2O3 thin films with surface nanowire were synthesized by electrodeposition and post annealing method for photoelectrocatalytic (PEC) water splitting. The thickness of the α-Fe2O3 films can be precisely controlled by adjusting the duration of the electrodeposition.
