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

2065 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

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

1360 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

Chihara K et al. suggested that 3BP2 is involved in the activation of Rac1 through the regulation of Vav3 by Syk-dependent phosphorylation of Tyr(426) following BCR stimulation. [Read the Full Post]

Loss of Siglec-14 reduces the risk of chronic obstructive pulmonary disease exacerbation

0 views | Mar 11 2017

Angata T et al found that Siglec-14 and its downstream signaling pathway facilitate the "infection-inflammation-exacerbation" axis of COPD disease progression, and may represent promising targets for therapeutic intervention. [Read the Full Post]

Metallothionein-1G facilitates sorafenib resistance through inhibition of ferroptosis

1300 views | Mar 10 2017

Sun X et al. found that knockdown of MT-1G by RNA interference increases glutathione depletion and lipid peroxidation, which contributes to sorafenib-induced ferroptosis. [Read the Full Post]

Identification of baicalein as a ferroptosis inhibitor by natural product library screening

1019 views | Mar 10 2017

Xie Y et al. found that baicalein enhances cellular anti-ferroptosis capacity and could be a potential therapeutic agent for ferroptosis-associated tissue injury. [Read the Full Post]
