The tetraspanin CD81 mediates the growth and metastases of human osteosarcoma

ConclusionBased on our findings we conclude that inhibition of CD81 suppresses intracellular signaling and reduces tumorigenesis and lung metastasis in osteosarcoma cells.

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

The accumulation of lingering senescent cells is an important contributing cause of degenerative aging. In this intriguing report, researchers note that senescent cells resulting from chemotherapy treatment can consume neighboring cells in order to prolong their survival. This is most likely the case for senescent cells in general, whatever their origin. This cellular cannibalism is probably detrimental to tissue function to some small degree, but, since senescent cells are always a tiny minority of all cells, even in old tissues, it is nowhere near as detrimental as the inflammatory signaling profile that accompanies cell...

In this study, we investigated the potential mechanisms of Glaucocalyxin A on EMT and metastasis of osteosarcoma. We found that Glaucocalyxin A inhibited migration and invasion of MG-63 and 143B cells. Moreover, Glaucocalyxin A increased the protein and mRNA levels of E-cadherin and decreased the protein and transcription expression of N-cadherin, Vimentin. Glaucocalyxin A also inhibited the protein and mRNA levels of EMT-associated transcription factor including Snail and Slug. Furthermore, Glaucocalyxin A inhibited transforming growth factor-β1 (TGF-β1)-induced migration, invasion and EMT of low-metastatic oste...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

The overall survival rate for pediatric osteosarcoma (OS), neuroblastoma (NB) and glioblastoma (GBM) in children with relapsed/refractory and metastatic disease remains dismal. Our group has successfully expanded peripheral blood Natural Killer cells (exPBNK) with irradiated feeder cells (Chu/Cairo, et al, Can Imm Res 2015). ALT-803 (N-803) is a superagonist of an IL-15 variant bound to an IL-15R αSu-Fc fusion with enhanced IL-15 biological activity (Zhu et al. 2009 J Immunol). Tim-3 was found expressed on active NK cells and its expression in cancer patientsÕ NK cells correlated with disease stage and prognosis.

Conclusion:Selinexor based combination regimens have shown better clinical response against AML as compared to monotherapy. The efficacy results in multiple myeloma and other hematological malignancies are also encouraging. The adverse events like cytopenias were common as in other chemotherapy regimens.DisclosuresNo relevant conflicts of interest to declare.

Kowol, Bernhard K. KepplerAbstractFibroblast growth factor receptor (FGFR) inhibitors like ponatinib and nintedanib are clinically approved for defined cancer patient cohorts but often exert dose-limiting adverse effects. Hence, we encapsulated FGFR inhibitors ponatinib, PD173074, and nintedanib into polylactic acid nanoparticles and liposomes to enable increased tumor accumulation/specificity and...

ConclusionThe cumulative incidence of secondary cancer varied among primary cancers. The primary cancer was closely associated with the secondary cancer but stem cell transplantation was a common risk factor for secondary cancers among CCSs.
