Wnt/β-catenin signaling is a critical regulator of skeletal physiology. However, previous studies have mainly focused on its roles in osteoblasts, while specific function osteoclasts unknown. This clinically important question because neutralizing antibodies against Wnt antagonists are promising new drugs for bone diseases. Here, we show that osteoclastogenesis, β-catenin induced during the macrophage colony-stimulating factor (M-CSF)-mediated quiescence-to-proliferation switch but...

Vimentin (VIM) is a type III intermediate filament that maintains cell integrity, and involved in migration, motility adhesion.

In addition,...

Abstract Background Hematopoiesis is a complex developmental process controlled by large number of factors that regulate stem cell renewal, lineage commitment and differentiation. Secreted proteins, including the hematopoietic growth factors, play critical roles in these processes have important biological clinical significance. We employed representational difference analysis to identify genes are differentially expressed during experimentally induced myeloid differentiation murine EML...

Enhancer of zeste homolog 2 (EZH2), a well-known methyltransferase, mediates histone H3 lysine 27 trimethylation (H3K27me3) and plays crucial role in several kidney disease models. However, its renal ischemia/reperfusion (I/R) injury still remains unclear. In this study, we found that EZH2 was positively related to I/R inhibition with DZNeP alleviated blocked the activation oxidative stress pyroptosis vivo. Similarly, either or si-RNA also exerted an inhibitory effect on...

For all newborn mammals, mother's milk is the perfect nourishment, crucial for their postnatal development. Here we report that, unexpectedly, maternal western diet consumption in mice causes production of toxic that contains excessive long chain and saturated fatty acids, which triggers ceramide accumulation inflammation nursing neonates, manifested as alopecia. This neonatal toxicity requires Toll-like-receptors (TLR), but not gut microbiota, because TLR2/4 deletion or TLR4 inhibition...

Studying the regulatory mechanisms of vascular formation human dental development may provide insights for related therapies. In this study, we utilized single-cell sequencing analysis compare gene expression stem cells (DPSCs) and endothelial (ECs) from developing mature pulps.

C/EBPepsilon is a member of the CCAAT/enhancer binding protein family basic region/leucine zipper transcriptional activators. The highly conserved between rodents and humans, its domain structure very similar to C/EBPalpha. In mice mRNA only detected in hematopoietic tissues, including embryonic liver adult bone marrow spleen. Within system, expressed primarily myeloid cells, promyelocytes, myelomonocytes, their differentiated progeny. To identify potential functions C/EBPepsilon, cell lines...

AbstractOsteoclasts are bone-resorbing cells essential for skeletal development, homeostasis, and regeneration. They derive from hematopoietic progenitors in the monocyte/macrophage lineage differentiate response to RANKL. However, precise nature of osteoclast is a longstanding important question. Using inducible peroxisome proliferator-activated receptor γ (PPARγ)-tTA TRE-GFP (green fluorescent protein) reporter mice, we show that reside specifically PPARγ-expressing bone marrow population...

Aberrant expression of long noncoding RNAs (lncRNAs) is associated with cancer tumorigenesis and progression. It has been suggested that lncRNAs may be potential clinical diagnostic prognostic biomarkers, therapeutic targets. In the present study, levels small nucleolar RNA host gene 15 (SNHG15) were significantly upregulated in renal cell carcinoma (RCC) tissues lines compared adjacent a proximal tubule epithelial line, as determined by reverse transcription‑quantitative polymerase chain...

Early detection and treatment are effective methods for the management of oral squamous cell carcinoma (OSCC), which can be facilitated by tumor-specific OSCC biomarkers. The epidermal growth factor receptor (EGFR) programmed death-ligand 1 (PD-L1) important therapeutic targets OSCC. Multispectral fluorescence molecular imaging (FMI) facilitate tumor multitarget expression with high sensitivity safety. Hence, we developed Nimotuzumab-ICG Atezolizumab-Cy5.5 probes, in combination...

Hydrogen sulfide (H2S) attenuates ischemia-reperfusion injury (IRI) in different organs. However, its mechanism of action renal IRI remains unclear. The present study investigated the hypothesis that H2S via induction heat shock proteins (HSPs).Adult Wistar rats were subjected to unilateral ischemia for 45 min followed by reperfusion 6 hr. One group underwent I/R without treatment, one was administered 150 μmol/l sodium hydrosulfide (NaHS) prior I/R, injected with 100 mg/kg quercetin (an HSP...
