A growing body of evidence demonstrates that autophagy, an evolutionarily conserved intracellular degradation process, is involved in the pathogenesis of atherosclerosis and has become a potential therapeutic target. Here we tested the effect of two inhibitors of phosphatidylinositol 3-kinase, 3-methyladenine (3-MA) and 2-(4-morpholinyl)-8-phenyl-chromone (LY294002), commonly used as inhibitors of autophagy, in atherosclerosis in apolipoprotein E(-/-) mice. Systemic application of 3-MA but not LY294002 markedly reduced the size of atherosclerotic plaque and increased the stability of lesions in high-fat diet-fed mice as compared with controls...

miR-148a-3p downregulation has emerged as a critical factor in cancer progression yet, the underlying mechanisms of miR-148a-3p expression pattern and its function in bladder cancer remains to be elucidated. Here, we illustrate that miR-148a-3p is frequently downregulated in bladder cancer and that its expression may be regulated by DNA methylation. DNA methyltransferase 1 (DNMT1) and miR-148a-3p function in a positive feedback loop in bladder cancer. miR-148a-3p overexpression functions as a tumor suppressor in bladder cancer cells...

We report the design and synthesis of a tetraphenylethene substituted with naphthalimide at the 4, 6 positions, named NI-2TPE. NI-2TPE exhibits strong solvent-dependent emission properties with combined ICT and AIE characteristics in THF-H2O systems. This probe was used directly on test papers to distinguish normal organic solvents using their emission colours under UV light based on its AIE and ICT nature. Thanks to the vinyl group in NI-2TPE, we synthesized a copolymer of NIPAM and NI-2TPE, termed P(NIPAM-co-NI-2TPE)...

Increasing evidence suggests that microRNA-101 (miR-101) is involved in the progression of various human cancers, including papillary thyroid carcinoma (PTC). However, the biological functions of miR-101 and underlying molecular mechanisms in PTC remain largely unknown. In this study, we demonstrated that miR-101 underexpression in PTC tissue was associated with lymph node metastasis and poor prognosis of PTC patients. MiR-101 reduced PTC cell proliferation, apoptosis resistance, and invasion. Ubiquitin-specific protease 22 (USP22) was confirmed as a direct target of miR-101...

Naringin is an active compound extracted from Rhizoma Drynariae, and studies have revealed that naringin can promote proliferation and osteogenic differentiation of bone marrow stromal cells (BMSCs). In this study, we explored whether naringin could promote osteogenic differentiation of BMSCs by upregulating Foxc2 expression via the Indian hedgehog (IHH) signaling pathway. BMSCs were cultured in basal medium, basal medium with naringin, osteogenic induction medium, osteogenic induction medium with naringin and osteogenic induction medium with naringin in the presence of the IHH inhibitor cyclopamine (CPE)...

The overactivation of immune cells plays an important role in the pathogenesis of hyperhomocysteinemia (HHcy)-accelerated atherosclerosis. Homocysteine (Hcy) activates B cell proliferation and Ab secretion; however, the underlying mechanisms for these effects remain largely unknown. Metabolic reprogramming is critical for lymphocyte activation and effector function. In this study, we showed that Hcy-activated B cells displayed an increase in both oxidative phosphorylation and glycolysis, with a tendency to shift toward the latter, as well as an accumulation of intermediates in the pentose phosphate pathway, to provide energy and biosynthetic substrates for cell growth and function...

AIMS: Chronic cocaine abuse decreases the inhibitory synaptic transmission via unknown mechanisms, while pharmacologically augmenting gamma-aminobutyric acid-ergic (GABAergic) transmission attenuates cocaine craving. Here, we propose that prolonged cocaine withdrawal downregulates GABAergic transmission and its important regulator gephyrin in medial prefrontal cortex (mPFC), in cocaine-conditioned place-preference (CPP) rats. METHODS: CPP test, patch clamp, and Western blot analysis are engaged to test this proposal...

BACKGROUND/AIMS: Bone marrow adipogenesis is one of the major characteristics of aged bone. Bone marrow mesenchymal stem cells (BMMSCs) prefer to differentiate into adipocytes instead of osteoblasts in the bone marrow cavity in aged hosts. The mechanism of formation and function of adipocytes in aged bone marrow needs further investigation. Osteoprotegerin (OPG) is a member of the tumor necrosis factor receptor (TNFR) super family, and it can inhibit the activities of osteoclasts. We found that adipocyte numbers increased in the bone marrow of Opg knockout mice...

Drug resistance is extremely common in nonsmall-cell lung cancer (NSCLC) and is one of the major problems in NSCLC chemotherapy. However, the detailed mechanisms remain largely unknown. Unfolded protein response (UPR) is involved in the tumorigenesis of NSCLC. Here, the authors demonstrated that the UPR promotes poly (ADP-ribose) polymerase activation (PARP) cleavage in NSCLC cells on doxorubicin treatment, which is a hallmark of apoptosis and caspase activation. In NSCLC cells, doxorubicin treatment triggers the UPR activation, which subsequently promotes doxorubicin-mediated apoptosis...

We investigated the edge states and quantum phase transition in graphene under an in-plane effective exchange field. The result shows that the combined effects of the in-plane effective exchange field and a staggered sublattice potential can induce zero-energy flat bands of edge states. Such flat-band edge states can evolve into helical-like ones in the presence of intrinsic spin-orbit coupling, with a unique spin texture. We also find that the bulk energy gap induced by the spin-orbit coupling and staggered sublattice potential can be closed and reopened with the in-plane effective exchange field, and the reopened bulk gap can be even larger than that induced by only the spin-orbit coupling and staggered sublattice potential, which is different from the case of an out-of-plane effective exchange field...

Hereditary hemochromatosis (HH) is a group of inherited iron-overload disorders associated with pathogenic defects in the genes encoding hemochromatosis (HFE), hemojuvelin (HJV/HFE2), hepcidin (HAMP), transferrin receptor 2 (TfR2), and ferroportin (FPN1/SLC40A1) proteins, and the clinical features are well described. However, there have been only a few detailed reports of HH in Chinese populations. Thus, there is insufficient patient information for population-based analyses in Chinese populations or comparative studies among different ethical groups...

Small ubiquitin-like modifier (SUMO)/sentrin-specific protease 1 (SENP1), a member of the SENP family, is highly expressed in several neoplastic tissues. However, the effect of SENP1 in acute promyelocytic leukemia (APL) has not been elucidated. In the present study, it was observed that SENP1 deficiency had no effect on the spontaneous apoptosis or differentiation of NB4 cells. Arsenic trioxide (As2O3) could induce the upregulation of endoplasmic reticulum (ER) stress, resulting in the apoptosis of NB4 cells...
