TNFAIP3 Derived from Skeletal Stem Cells Alleviated Rat Osteoarthritis by Inhibiting the Necroptosis of Subchondral Osteoblasts.

Recent investigations have shown that the necroptosis of tissue cells in joints is important in the development of osteoarthritis (OA). This study aimed to investigate the potential effects of exogenous skeletal stem cells (SSCs) on the necroptosis of subchondral osteoblasts in OA. Human SSCs and subchondral osteoblasts isolated from human tibia plateaus were used for Western blotting, real-time PCR, RNA sequencing, gene editing, and necroptosis detection assays.

Effects of template molecules on the structures and luminescence intensities of a series of porous Tb-MOFs based on the 2-nitroterephthalate ligand.

Four novel porous Tb(iii) metal-organic frameworks (Tb-MOFs) have been designed and prepared hydrothermally from 2-nitroterephthalate (2-Hntp), namely {[Tb(2-ntp)(HO)]·HO} (1), {[Tb(2-ntp)(HO)]·4,4'-Hbipy} (2), {[Tb(2-ntp)(HO)]·2,4-Hbipy} (3), and {[Tb(2-ntp)(HO)]·(1,4-Hbbi)} (4) (4,4'-bipy = 4,4'-bipyridine; 2,4-bipy = 2,4-bipyridine; 1,4-bbi = 1,4-bisbenzimidazole). X-ray diffraction structural analyses show these Tb-MOFs are porous and are based on Tb ions and 2-nitroterephthalate, in which water molecules (1) or protonated N-donor ligands (2-4) exist as templates. The fluorescence properties of complexes 1-4 could be associated with the characteristic peaks of Tb(iii) ions, and the existence of different guest molecules affects the intensities of peaks, which means that these could be potential fluorescence materials, with intensities adjusted using guests.

Discovery of 5,6-diaryl-1,2,4-triazines hybrids as potential apoptosis inducers.

A series of 5,6-diaryl-1,2,4-triazines hybrids bearing a 1,2,3-triazole linker were synthesized by molecular hybridization strategy and evaluated for antiproliferative activity against three selected cancer cell lines (MGC-803, EC-109 and PC-3). The first structure-activity relationship (SAR) for these 5,6-diaryl-1,2,4-triazines is explored in this report with evaluation of 15 variants of the structural class. Among these chemical derivatives, 3-(((1-(4-fluorobenzyl)-1H-1,2,3-triazol-4-yl)methyl)thio)-5,6-diphenyl-1,2,4-triazine (11E) showed the more potent inhibitory effect against three cell lines than 5-Fu.

[Treatment of Chronic Graft versus Host Disease -Review].

Chronic graft versus host disease (cGVHD) is the major reason of late non-relapse related death after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The therapeutic regimen based on glucocorticoids remains as the standard initial treatment of cGVHD. But due to the significant side effects and unsatisfactory outcomes, particularly for patients with steroid-refractory disease, the more effective and less toxic therapies should be needed.

[Advances of Diagnostic Biomarkers on Acute Graft Versus Host Disease -Review].

Acute graft-versus-host disease (aGVHD) is one of the main complications after allogeneic hematopoietic stem cell transplantation (HCT), resulting in considerable morbidity and mortality. Diagnosis of aGVHD is typically based on clinical presentation and confirmed by biopsy. In recent years, aGVHD researches have been focused on diagnostic biomarkers, and several microRNAs, cytokines and immunoregulated cells have been dicovered currently.
