Nicotine-Mediated Ca2+ -Influx Induces IL-8 Secretion in Oral Squamous Cell Carcinoma Cell

2652 views | Mar 14 2017

Tsunoda K et al. suggested that the binding of nicotine to nAChR induces Ca(2+) influx, which results in the activation and phosphorylation of CaMK II and NF-κB p65, respectively. Nicotine-mediated IL-8 induction should be a trigger for the initiation of various diseases. [Read the Full Post]

HDAC4 mediates IFN-γ induced disruption of energy expenditure-related gene expression by repressing SIRT1 transcription in skeletal muscle cells

Vorinostat Enhances Cytotoxicity of SN-38 and Temozolomide in Ewing Sarcoma Cells and Activates STAT3/AKT/MAPK Pathways

0 views | Mar 13 2017

Sampson VB et al suggested that potent antiproliferative and proapoptotic activity were demonstrated for ST induced DNA damage before or simultaneous with HDAC inhibition and cell death was mediated through the p53 pathway. These observations may aid in designing new protocols for treating pediatric patients with high-risk EWS. [Read the Full Post]

0 views | Mar 12 2017

Lin YC et al found that the control of Syk activity might be effective to modulate NLRP3 inflammasome activation and treat NLRP3-related immune diseases. [Read the Full Post]

Malassezia yeasts activate the NLRP3 inflammasome in antigen-presenting cells via Syk-kinase signalling

0 views | Mar 12 2017

Kistowska M et al identified Malassezia spp. as potential strong inducers of pro-inflammatory responses when taken up by antigen-presenting cells and identify C-type lectin receptors and the NLRP3 inflammasome as crucial actors in this process. [Read the Full Post]

GRP78 confers the resistance to 5-FU by activating the c-Src/LSF/TS Axis in hepatocellular carcinoma

1864 views | Mar 11 2017

Gu YJ, et al. further identified that GRP78 interacts physically with c-Src through its ATPase domain and promotes the phosphorylation of c-Src, which in turn increases the expression of LSF in the nucleus. Together, GRP78 confers the resistance to 5-FU by up-regulating the c-Src/LSF/TS axis via its ATPase domain. [Read the Full Post]

Tyrosine phosphorylation of 3BP2 is indispensable for the interaction with VAV3 in chicken DT40 cells

0 views | Mar 11 2017
