A sequential scheme including PTT and 2'3'-cGAMP/CQ-LP reveals the antitumor immune function of PTT through the type I interferon pathway

16 views | Nov 19 2023

The study elucidates the mechanisms underlying Photothermal Therapy (PTT) by demonstrating STING-dependent and STING-independent type I interferon production, and proposes a synergistic approach using a novel liposome co-loaded with the STING agonist cGAMP and chloroquine, which, when combined with PTT, induces significant tumor cell apoptosis and modulates the tumor microenvironment, providing crucial insights for the rational design of potent antitumor combination treatments.

MEK inhibition sensitizes pancreatic cancer to STING agonism by tumor-cell intrinsic amplification of type I interferon signaling

82 views | Aug 28 2023

MEK inhibitors synergistically enhance the cytotoxic effects of STING agonists on pancreatic ductal adenocarcinoma (PDAC) cells by suppressing NF-κB activation and promoting Type I interferon-dependent cell death. [Read the Full Post]

Radiation induces IRAK1 expression to promote radioresistance by suppressing autophagic cell death via decreasing the ubiquitination of PRDX1 in glioma cells

93 views | Jun 06 2023

The study found that overexpression of IRAK1 in glioma patients is associated with a poor prognosis, and that IRAK1 knockdown inhibits malignancy and enhances radiosensitivity by targeting the IRAK1-PRDX1 axis. [Read the Full Post]

Licorice extract inhibits the cGAS-STING pathway and protects against non-alcoholic steatohepatitis

27 views | May 08 2023

Licorice extract may have therapeutic potential for non-alcoholic steatohepatitis by inhibiting the cGAS-STING pathway and improving hepatic inflammation and fibrosis. [Read the Full Post]

PHLPP1 regulates PINK1-parkin signalling and life span

63 views | May 08 2023

PHLPP1 regulates mitochondrial homeostasis by promoting tubularity or fragmentation depending on cellular conditions and interacts with calcineurin and PINK1 under basal conditions, while its depletion in C. elegans leads to mitochondrial fission, lifespan extension, and enhanced survival under oxidative stress.
