Gasdermin proteins except DFNB59 are the executioners of pyroptotic cell death. Cleavage of a gasdermin by an active protease causes lytic cell death. Gasdermin C (GSDMC) is cleaved by caspase-8 in response to macrophage-secreted TNF-α. Upon cleavage, the GSDMC-N domain is liberated and oligomerized, followed by pore formation in the plasma membrane. GSDMC cleavage, LDH release, and plasma membrane translocation of GSDMC-N domain are the reliable markers for GSDMC-mediated cancer cell pyroptosis (CCP). Here, we describe the methods for examining GSDMC-mediated CCP.

<b>Background and Objective:</b> Cervical cancer is the second most common cancer in Indonesia, where traditional herbal treatments like <i>Zanthoxylum acanthopodium</i> (andaliman) are culturally used. Investigating protein biomarkers such as E7, pRb, EGFR and p16 can help assess the efficacy of these treatments. <b>Materials and Methods:</b> There were 5 groups in this study: 2 control groups (C- and C+) and 3 treatment groups (each receiving one of three doses).

Radiodynamic therapy that employs X-rays to trigger localized reactive oxygen species (ROS) generation can tackle the tissue penetration issue of phototherapy. Although calcium tungstate (CaWO) shows great potential as a radiodynamic agent benefiting from its strong X-ray absorption and the ability to generate electron-hole (e-h) pairs, slow charge carrier transfer and fast e-h recombination greatly limit its ROS-generating performance. Herein, via a one-pot wet-chemical method, oxygen vacancy-rich amorphous/crystalline heterophase CaWO nanoparticles (Ov-a/c-CaWO NPs) with enhanced radiodynamic effect are synthesized for radiodynamic-immunotherapy of cancer.

Poor response to 5-fluorouracil (5-FU) remains an obstacle in the treatment of gastric cancer (GC). Super enhancers (SEs) are crucial for determining tumor cell survival under drug pressure. SE landscapes related to 5-FU-resistance are mapped to GC using chromatin immunoprecipitation-sequencing (ChIP-Seq).

Patient-derived organoids represent a novel platform to recapitulate the cancer cells in the patient tissue. While cancer heterogeneity has been extensively studied by a number of omics approaches, little is known about the spatiotemporal kinase activity dynamics. Here we applied a live imaging approach to organoids derived from 10 pancreatic ductal adenocarcinoma (PDAC) patients to comprehensively understand their heterogeneous growth potential and drug responses.
