SS18-SSX drives TYK2 expression to activate STAT3/Bcl2 axis, facilitating apoptosis evasion and advancing synovial sarcoma progression.

Synovial sarcoma (SS) is a rare soft tissue sarcoma characterized by high-grade malignancy and poor prognosis. Preliminary research indicates that apoptosis evasion is a key factor in SS progression, primarily attributed to the overexpression of anti-apoptotic genes. However, the mechanisms underlying this phenomenon are still not fully understood.

Overexpression of BMP‑7 reverses TGF‑β1‑induced epithelial‑mesenchymal transition by attenuating the Wnt3/β‑catenin and TGF-β1/Smad2/3 signaling pathways in HK‑2 cells.

Tubular epithelial cells undergoing epithelial‑mesenchymal transition (EMT) is a crucial event in the progression of renal interstitial fibrosis (RIF). Bone morphogenetic protein‑7 (BMP‑7) has been reported to exhibit anti‑fibrotic functions in various renal diseases. However, the function of BMP‑7 in regulating EMT and the progression of RIF remains largely unknown.

The effect of bone marrow mesenchymal stem cell and nano-hydroxyapatite/collagen I/poly-L-lactic acid scaffold implantation on the treatment of avascular necrosis of the femoral head in rabbits.

For avascular necrosis of the femoral head (ANFH), repair and regeneration are difficult because of the edema and high pressure caused by continuous ischemia and hypoxia. Core decompression (CD) is a classic method for treating early ANFH before the collapse of the femoral head; however, its effect is still controversial. To improve the therapeutic effect of CD on ANFH, a novel tissue-engineered bone (TEB) was constructed by combining bone marrow mesenchymal stem cells (BMSCs) with nano-hydroxyapatite/collagen I/poly-L-lactic acid (nHAC/PLA) scaffolds and implanting the TEB into the bone tunnel of CD.

A specific affinity cyclic peptide enhances the adhesion, expansion and proliferation of rat bone mesenchymal stem cells on β‑tricalcium phosphate scaffolds.

Tissue engineering therapy using bone mesenchymal stem cells (BMSCs) combined with a scaffold is a promising strategy.

Adenovirus-delivered PDCD5 counteracts adriamycin resistance of osteosarcoma cells through enhancing apoptosis and inhibiting Pgp.

In the present study, we investigated the roles of PDCD5 (programmed cell death 5) in multidrug re-sistance (MDR) of osteosarcoma cells and the possible lurking mechanisms. An adenovirus expression vector of PDCD5 was constructed and transfected into human adriamycin-resistant osteosarcoma cell line Saos-2/ADM. We found that up-regulation of PDCD5 could significantly enhance the sensitivity of Saos-2/ADM cells towards vincristine, methotrexate, cisplatin and arsenic trioxide (As2O3), and could decrease the capacity of cells to efflux adriamycin.

Our previous findings confirmed that the nerve growth factor-containing fibrin glue membrane provides a good microenvironment for peripheral nerve regeneration; however, the precise mechanism remains unclear. p75 neurotrophin receptor (p75(NTR)) plays an important role in the regulation of peripheral nerve regeneration. We hypothesized that a nerve growth factor-containing fibrin glue membrane can promote neural regeneration by up-regulating p75(NTR) expression.

Methods: A model of New Zealand rabbit ulnar segments devitalized by hypertonic saline was established and then reimplanted in situ. The ulnar specimens were taken for examination of X-rays, light microscope and three-point-bend test at the end of 3, 6, 12, and 24 weeks postoperatively.

AtACDO1, an ABC1-like kinase gene, is involved in chlorophyll degradation and the response to photooxidative stress in Arabidopsis.

ABC1 (activity of bc1 complex) is a newly discovered atypical kinase in plants. Here, it is reported that an ABC1 protein kinase-encoded gene, AtACDO1 (ABC1-like kinase related to chlorophyll degradation and oxidative stress), located in chloroplasts, was up-regulated by methyl viologen (MV) treatment. AtACDO1 RNAi (RNA interference) plants showed developmental defects, including yellow-green leaves and reduced contents of carotenoids and chlorophyll; the chlorophyll reduction was associated with a change in the numbers of chlorophyll-binding proteins of the photosynthetic complexes.
