Motivating role of type H vessels in bone regeneration.

Coupling between angiogenesis and osteogenesis has an important role in both normal bone injury repair and successful application of tissue-engineered bone for bone defect repair. Type H blood vessels are specialized microvascular components that are closely related to the speed of bone healing. Interactions between type H endothelial cells and osteoblasts, and high expression of CD31 and EMCN render the environment surrounding these blood vessels rich in factors conducive to osteogenesis and promote the coupling of angiogenesis and osteogenesis.

The application of bone marrow mesenchymal stem cells and biomaterials in skeletal muscle regeneration.

Skeletal muscle injuries have bothered doctors and caused great burdens to the public medical insurance system for a long time. Once injured, skeletal muscles usually go through the processes of inflammation, repairing and remodeling. If repairing and remodeling stages are out of balance, scars will be formed to replace injured skeletal muscles.

A Transcriptional Regulatory Loop of Master Regulator Transcription Factors, PPARG, and Fatty Acid Synthesis Promotes Esophageal Adenocarcinoma.

Although obesity is one of the strongest risk factors for esophageal adenocarcinoma, the molecular mechanisms underlying this association remain unclear. We recently identified four esophageal adenocarcinoma-specific master regulator transcription factors (MRTF) ELF3, KLF5, GATA6, and EHF. In this study, gene-set enrichment analysis of both esophageal adenocarcinoma patient samples and cell line models unbiasedly underscores fatty acid synthesis as the central pathway downstream of three MRTFs (ELF3, KLF5, GATA6).

MBD2 Mediates Septic AKI through Activation of PKCη/p38MAPK and the ERK1/2 Axis.

However, the role and regulation of MBD2 in septic AKI are unknown. Herein, MBD2 was induced by lipopolysaccharide (LPS) in Boston University mouse proximal tubules (BUMPTs) and mice.

Controlled Delivery of Growth Factor by Hierarchical Nanostructured Core-Shell Nanofibers for the Efficient Repair of Critical-Sized Rat Calvarial Defect.

Electrospun nanofibers have received much attention as bone tissue-engineered scaffolds for their capacity to mimic the structure of natural extracellular matrix (ECM). Most studies have reproduced nanofibers with smooth surface for tissue engineering. This is quite different from the triple-helical nanotopography of natural collagen nanofibrils.

Identification of novel CEBPA double mutations capable of promoting familial AML via the suppression of myeloid differentiation.

CCAAT-enhancer-binding protein α (CEBPA) gene carrying two mutations (CEBPA double mutations) is known to promote familial acute myeloid leukemia (AML). However, the underlying mechanism by which CEBPA double mutations promote AML remains poorly understood. Here we report that a family with three generations suffering from familial AML carries novel double mutations of CEBPA.

Neurotrophic effects of dental pulp stem cells in repair of peripheral nerve after crush injury.

Background: Nerve diseases and injuries, which are usually accompanied by motor or sensory dysfunction and disorder, impose a heavy burden upon patients and greatly reduce their quality of life. Dental pulp stem cells (DPSCs), derived from the neural crest, have many characteristics that are similar to those of neural cells, indicating that they can be an ideal source for neural repair.

Aim: To explore the potential roles and molecular mechanisms of DPSCs in crushed nerve recovery.

Phosphorylated STAT3 suppresses microRNA-19b/1281 to aggravate lung injury in mice with type 2 diabetes mellitus-associated pulmonary tuberculosis.

Type 2 diabetes mellitus (T2DM) is a risk factor for pulmonary tuberculosis (PTB) and increased mortality. This work focused on the functions of phosphorylated STAT3 in lung injury in mouse with T2DM-associated PTB and the molecules involved. A mouse model with T2DM-PTB was induced by administrations of streptozotocin, nicotinamide and mycobacterium tuberculosis (Mtb).

Prevalence of comprehensive DNA damage repair gene germline mutations in Chinese prostate cancer patients.

Germline DNA damage repair (DDR) deficiency has been associated with increased cancer risk, poor prognosis and therapeutic opportunity for prostate cancer (PCa) patients. However, the landscape of germline mutations in PCa covering comprehensive DDR genes has not been reported. We performed whole-exome sequencing in 246 patients who meet the National Cancer Center Network guidelines for genetic testing and analyzed variants in 276 DDR genes, which was from the Cancer Genome Atlas.

Interleukin-4-loaded hydrogel scaffold regulates macrophages polarization to promote bone mesenchymal stem cells osteogenic differentiation via TGF-β1/Smad pathway for repair of bone defect.

Objective: Tissue engineering is a promising strategy for repair of large bone defect. However, the immune system reactions to biological scaffold are increasingly being recognized as a crucial factor influencing regeneration efficacy. In this study, a bone-bioactive hydrogel bead loaded with interleukin-4 (IL-4) was used to regulate macrophages polarization and accelerate bone regeneration.

Adipose-derived stem cell therapy shows promising results for secondary lymphedema.

Lymphedema is mainly identified by progressive soft tissue swelling in impaired lymphatic system. Secondary lymphedema attributed to cancer therapy, parasite infection, and trauma remains a serious global disease. Patients with lymphedema suffer swelling, pain, and fatigue, with the dysfunction of the deformed extremities reducing the quality of life and increasing the risk of infection and lymphangiosarcoma.

Inhibition of FvMYB10 transcriptional activity promotes color loss in strawberry fruit.

FvMYB10 protein has been proved to be a transcriptional switch for anthocyanin biosynthesis in strawberry. A single nucleotide mutation in R2 domain of FvMYB10, named as FvmMYB10, is found to be responsible for the white color in strawberry variety 'Yellow Wonder'. However, the mechanism of FvmMYB10 suppresses anthocyanin biosynthesis in strawberry is largely unknown.

ISL2 modulates angiogenesis through transcriptional regulation of ANGPT2 to promote cell proliferation and malignant transformation in oligodendroglioma.

Oligodendroglioma is an important type of lower-grade glioma (LGG), which is a slowly progressing brain tumor. Many LGGs eventually transform into a more aggressive or malignant type. Enhanced angiogenesis is a characteristic of malignantly transformed oligodendroglioma (m-oligodendroglioma).

The HD-ZIP IV transcription factor Tril regulates fruit spine density through gene dosage effects in cucumber.

Trichomes and fruit spines are important traits that directly affect the appearance quality and commercial value of cucumber (Cucumis sativus). Tril (Trichome-less), encodes a HD-Zip IV transcription factor that plays a crucial role in the initiation of trichomes and fruit spines, but little is known about the details of the regulatory mechanisms involved. In this study, analysis of tissue expression patterns indicated that Tril is expressed and functions in the early stages of organ initiation and development.

In situ modification of BiVO nanosheets on graphene for boosting photocatalytic water oxidation.

Owing to the sluggish water oxidation process, unearthing an ideal model for disclosing the impact of an architectural approach on the water oxidation activity of photocatalysts becomes a vital issue. Here, we propose an innovative in situ modification strategy for constructing ultrapure BiVO nanosheets on graphene (u-BVG) toward the accelerated photocatalytic water oxidation reaction. Considering the Mott-Schottky heterojunctions at the contact interface in u-BVG, the feasible electron transfer from excited BiVO to graphene facilitates the holes to migrate onto the BiVO surface for the water oxidation reaction.

A novel selective autophagy receptor, CCDC50, delivers K63 polyubiquitination-activated RIG-I/MDA5 for degradation during viral infection.

Autophagy is a conserved process that delivers cytosolic substances to the lysosome for degradation, but its direct role in the regulation of antiviral innate immunity remains poorly understood. Here, through high-throughput screening, we discovered that CCDC50 functions as a previously unknown autophagy receptor that negatively regulates the type I interferon (IFN) signaling pathway initiated by RIG-I-like receptors (RLRs), the sensors for RNA viruses. The expression of CCDC50 is enhanced by viral infection, and CCDC50 specifically recognizes K63-polyubiquitinated RLRs, thus delivering the activated RIG-I/MDA5 for autophagic degradation.
