Allogeneic islet cells implant on poly-l-lactide matrix to reduce hyperglycaemia in streptozotocin-induced diabetic rat

0 views | Oct 22 2018

Hendrawan S et al. indicated the islet cell matrix implant reduced the blood glucose levels although complete normo-glycaemia was not established. The islet cell matrix implant may serve as an additional option for islet cell transplantation using 3D scaffold platforms for better survival and function of the islet cells. [Read the Full Post]

Allogeneic islet cells implant on poly-l-lactide matrix to reduce hyperglycaemia in streptozotocin-induced diabetic rat

202 views | Oct 19 2018

Hendrawan S et al. found that 82% of seeded islet cells attached to the matrices. In the IMI group blood glucose levels were significantly reduced after implantation compared with before implantation across several time points. In the IMI group beta-cells and insulin-positive cells were identified at the implant site. [Read the Full Post]

Gupta S et al. found that LSD1 inhibition with HCI-2509 decreases the c-MYC level in poorly differentiated prostate cancer cell lines and has a therapeutic potential in castration- and docetaxel-resistant prostate cancer. [Read the Full Post]

Tumor-secreted anterior gradient-2 binds to VEGF and FGF2 and enhances their activities by promoting their homodimerization.

354 views | Oct 18 2018

Guo H et al. proposed that the secreted AGR2 is a blockable molecular target, which acts as a chaperon-like enhancer to VEGF and FGF2. [Read the Full Post]

Retinoic acid and TGF-β signalling cooperate to overcome MYCN-induced retinoid resistance

532 views | Oct 15 2018

Duffy DJ et al. provided a powerful precision oncology tool for identifying the driving signalling networks for malignancies not primarily driven by somatic mutations, such as paediatric cancers. By applying global omics approaches to the signalling networks regulating neuroblastoma differentiation and stemness, we have determined the pathways involved in the MYCN-mediated retinoid resistance, with TGF-β signalling being a key regulator. These findings revealed a number of combination treatments likely to improve clinical response to retinoid therapy, including co-treatment with retinoids and KGN, which may prove valuable in the treatment of high-risk MYCN-amplified neuroblastoma.
