Here we report the room temperature, atmospheric synthesis of Mn-doped cesium lead halide (CsPbX3) perovskite QDs. The synthesis is performed without any sort of protection and the dual-color emission mechanism is revealed by density functional theory. The Mn concentration reaches a maximum atomic percentage of 37.73 at%, which is significantly higher in comparison to those achieved in earlier reports via high temperature hot injection method. The optical properties of as-prepared nanocrystals (NCs) remain consistent even after several months...

NADPH oxidase Nox4-derived reactive oxygen species (ROS) play important roles in renal fibrosis. Our previous study demonstrated that intermedin (IMD) alleviated unilateral ureteral obstruction (UUO)-induced renal fibrosis by inhibition of ROS. However, the precise mechanisms remain unclear. Herein, we investigated the effect of IMD on Nox4 expression and NADPH oxidase activity in rat UUO model, and explored if these effect were achieved through cAMP-PKA pathway, the important post-receptor signal transduction pathway of IMD, in TGF-β1-stimulated rat proximal tubular cell (NRK-52E)...

Increasing the self-resistance levels of Streptomyces is an effective strategy to improve the production of antibiotics. To increase the oxytetracycline (OTC) production in Streptomyces rimosus, we investigated the cooperative effect of three co-overexpressing OTC resistance genes: one gene encodes a ribosomal protection protein (otrA) and the other two express efflux proteins (otrB and otrC). Results indicated that combinational overexpression of otrA, otrB, and otrC (MKABC) exerted a synergetic effect. OTC production increased by 179% in the recombinant strain compared with that of the wild-type strain M4018...

The nucleoside adenosine is a potent regulator of vascular homeostasis, but it remains unclear how expression or function of the adenosine-metabolizing enzyme adenosine kinase (ADK) and the intracellular adenosine levels influence angiogenesis. We show here that hypoxia lowered the expression of ADK and increased the levels of intracellular adenosine in human endothelial cells. Knockdown (KD) of ADK elevated intracellular adenosine, promoted proliferation, migration, and angiogenic sprouting in human endothelial cells...

Functions and mechanisms of microRNA (miRNA) involved in colorectal cancer (CRC) metastasis are largely unknown. Here, a miRNA microarray analysis was performed in CRC primary tissues and metastatic hepatic tissues to disclose crucial miRNA involved in CRC metastasis. MiR-133b was decreased and negatively correlated with metastasis in CRC. Overexpression of miR-133b significantly suppressed metastasis of CRC in vitro and in vivo. HOXA9 was identified as a direct and functional target of miR-133b. In addition, HOXA9 was negatively correlated with miR-133b and promoted CRC malignant progress...

Surface-enhanced Raman scattering (SERS) by use of noble metal nanoparticles has become a powerful tool to determine a low-concentration target by unique spectral fingerprints, but it is still limited to the Raman-inactive and nonresonant biomolecules such as amine acids, proteins, and hormones. Here, we report an Ehrlich reaction based derivative strategy in combination with gold nanoparticles (Au NPs) hotspots for the selective detection of indole-like plant hormones by SERS spectroscopy. Ehrlich reaction of p-(dimethylamino)benzaldehyde (PDAB) with the indole ring chemically transformed plant hormone indole-3-butyric acid (IBA) into a Raman-active and resonant derivative with an extended π-conjugated system in the form of a cation, which produced a new absorption band at 626 nm...

Nasopharyngeal carcinoma (NPC) is a unique subtype of head and neck cancer, with tendency to spread to regional lymph nodes and distant organs at early stage. Vimentin, a major cytoskeletal protein constituent of the intermediate filament, plays a critical role in the epithelial-mesenchymal transition. Overexpression of vimentin is considered to be a critical prerequisite for metastasis in numerous human cancers. Therefore, targeting vimentin for cancer therapy has gained a lot of interest. In the present study, we detected vimentin expression in NPC tissues and found that overexpression of vimentin is associated with poor prognosis of NPC patients...

Muscle-invasive bladder cancer (MIBC) is an aggressive disease with limited therapeutic options. Although immunotherapies are approved for MIBC, the majority of patients fail to respond, suggesting existence of complementary immune evasion mechanisms. Here, we report that the PPARγ/RXRα pathway constitutes a tumor-intrinsic mechanism underlying immune evasion in MIBC. Recurrent mutations in RXRα at serine 427 (S427F/Y), through conformational activation of the PPARγ/RXRα heterodimer, and focal amplification/overexpression of PPARγ converge to modulate PPARγ/RXRα-dependent transcription programs...

Long-noncoding RNAs (lncRNAs) are a group of transcripts that are longer than 200 nucleotides and do not code for proteins. However, this class of RNAs plays pivotal regulatory roles. The mechanism of their action is highly complex. Mounting evidence shows that lncRNAs can regulate cancer onset and progression in a variety of ways. They can not only regulate cancer cell proliferation, differentiation, invasion and metastasis, but can also regulate glucose metabolism in cancer cells through different ways, such as by directly regulating the glycolytic enzymes and glucose transporters (GLUTs), or indirectly modulating the signaling pathways...

Obesity and type 2 diabetes are linked with chronic, low-grade inflammation in visceral adipose tissue (VAT). A unique population of VAT-resident CD4(+)Foxp3(+) Tregs plays a crucial role in regulating VAT inflammation and metabolic homeostasis. VAT-resident Tregs display a highly restricted TCR repertoire, suggesting they recognize certain autoantigen(s) in VAT. A dramatic reduction of VAT-resident Tregs has been shown to closely correlate with obesity-related VAT chronic inflammation and metabolic disorders...

WSL4 encodes a KCS6 protein which is required for cuticular wax accumulation in rice. Very long chain fatty acids (VLCFAs) are essential precursors for cuticular wax biosynthesis. VLCFA biosynthesis occurs in the endoplasmic reticulum and requires the fatty acid elongase (FAE) complex. The β-ketoacyl-coenzyme A synthase (KCS) catalyzes the first step of FAE-mediated VLCFA elongation. Here we characterized the Wax Crystal-Sparse Leaf 4 (WSL4) gene involved in leaf cuticular wax accumulation in rice. The wsl4 mutant displayed a pleiotropic phenotype including dwarfism, less tiller numbers and reduced surface wax load...
