Interleukin 37 limits monosodium urate crystal-induced innate immune responses in human and murine models of gout

312 views | Nov 09 2018

Liu L et al. revealed that IL-37 limits runaway inflammation initiated by MSU crystal-induced immune responses, partly in a Mertk-dependent fashion. Thus, rhIL-37 has both preventive and therapeutic effects in gouty arthritis. [Read the Full Post]

Identification of the Serine Biosynthesis Pathway as a Critical Component of BRAF Inhibitor Resistance of Melanoma, Pancreatic, and Non-Small Cell Lung Cancer Cells

334 views | Nov 08 2018

The novel aspects of this study are the direct identification of serine biosynthesis as a critical mechanism of BRAF V600E inhibitor resistance and the first successful example of using gemcitabine + BRAFis in combination to kill previously drug-resistant cancer cells, creating the translational potential of pretreatment with gemcitabine prior to BRAFi treatment of tumor cells to reverse resistance within the mutational profile and the WT.

Curcumin and its cyclohexanone analogue inhibited human Equilibrative nucleoside transporter 1 (ENT1) in pancreatic cancer cells

986 views | Nov 08 2018

Revalde JL et al. concluded that curcumin and A13 are inhibitors of the ENT1 transporter, but only at high concentrations (2-20µM). [Read the Full Post]

Inhibition of glioblastoma cell proliferation, migration and invasion by the proteasome antagonist carfilzomib

0 views | Nov 08 2018

Areeb Z, et al. indicated carfilzomib represents a novel, yet FDA-approved agent for the treatment of glioblastoma multiforme. [Read the Full Post]

Dying glioma cells establish a proangiogenic microenvironment through a caspase 3 dependent mechanism

642 views | Nov 07 2018

Feng X et al. illustrated that caspase 3 activation in dying glioma cells unfavorably supported post-irradiation angiogenesis. This double-edged role of caspase 3 suggested that taming caspase 3 from the opposite side, not always activating it, may provide novel therapeutic strategies due to restricted post-irradiation angiogenesis.

The afatinib resistance of in vivo generated H1975 lung cancer cell clones is mediated by SRC/ERBB3/c-KIT/c-MET compensatory survival signaling

0 views | Nov 07 2018

Booth L et al. indicated that inhibition of ERBB3 signaling via both blockade of SRC and ERBB1 results in tumor cell death. [Read the Full Post]

Pro-survival signal inhibition by CDK inhibitor dinaciclib in Chronic Lymphocytic Leukaemia

0 views | Nov 06 2018

Chen Y et al. showed that dinaciclib targets multiple pro-survival signalling pathways in CLL, which provides a mechanistic explanation for its potent induction of apoptosis. They also support a therapeutic application of cyclin-dependent kinase inhibitors in CLL in combination with other relevant targeted therapies. [Read the Full Post]

Vascular Endothelial Growth Factor-A Increases the Aqueous Humor Outflow Facility

706 views | Nov 06 2018

Fujimoto T et al. suggested that VEGF-A may regulate the conventional aqueous outflow of SCE cells through VEGFR2. [Read the Full Post]

Treatment to sustain a Th17-type phenotype to prevent skewing toward Treg and to limit premalignant lesion progression to cancer

468 views | Nov 05 2018

Young MR et al. showed that the treatment approach not only sustained the Th17 phenotype, but also increased distal spleen cell and regional lymph node cell production of other stimulatory/inflammatory mediators and slowed premalignant lesion progression to cancer. [Read the Full Post]

Dihydroartemisinin inhibits TCTP-dependent metastasis in gallbladder cancer

No preclinical rationale for IGF1R directed therapy in chondrosarcoma of bone

0 views | Nov 04 2018

Peterse EF et al. indicated that the IGF pathway is not essential for chondrosarcoma growth, migration or chemoresistance. Furthermore, IGF1R is only minimally expressed in chondrosarcoma primary tumours. Therefore, the IGF pathway is not expected to be an effective therapeutic target for chondrosarcoma of bone.
