Oncolytic therapy, inducing cell death via cell membrane lysis, holds considerable promise in cancer treatment. However, achieving precise control over the structure and function of oncolytic materials for highly selective oncolytic therapy is a key challenge in the context of the subtle differences between tumor and normal tissues/cells. Herein, we report the development of pH-ultrasensitive oncolytic polyesters (pOPs) with an alternating sequence of ionizable and hydrophobic groups.

Objective: This study aims to identify the risk factors for systemic inflammatory response syndrome (SIRS) after minimally invasive percutaneous nephrolithotomy (PCNL) with a controlled irrigation pressure and to find which patients undergoing PCNL are likely to develop SIRS under the pressure-controlled condition.

Methods: A total of 303 consecutive patients who underwent first-stage PCNL in our institute between July 2016 and June 2018 were retrospectively reviewed. All the procedures were performed with an 18 F tract using an irrigation pump setting the irrigation fluid pressure at 110 mmHg and the flow rate of irrigation at 0.

The lysine-specific demethylase 5 (KDM5) family, a key post-translational modification of chromatin, can shape tumor immune microenvironment. Here, we performed an extensive clinical and bioinformatic analysis to explore the association between KDM5 mutation and tumor immunity and its impact on the outcomes in pan-cancer immunotherapy. In 2943 patients across 12 tumor types treated with immune checkpoint inhibitors, KDM5-mutant tumors were associated with favorable overall survival (hazard ratio, 0.

Background: Bacterial pathogens frequently encounter host-derived metabolites during their colonization and invasion processes, which can serve as nutrients, antimicrobial agents, or signaling molecules for the pathogens. The essential nutrient choline (Cho) is widely known to be utilized by a diverse range of bacteria and may undergo conversion into the disease-associated metabolite trimethylamine (TMA). However, the impact of choline metabolism on bacterial physiology and virulence remains largely unexplored.

Microglia are highly specialized resident macrophages in the central nervous system that play a pivotal role in modulating neuroinflammation. Microglial plasticity is essential for their function, allowing them to polarize into proinflammatory M1-like or anti-inflammatory M2-like phenotypes. However, the mechanisms driving M1 and M2 microglial induction during retinal degeneration remain largely unexplored.

Recent studies recommend sublobectomy as a surgical approach for non-small cell lung cancer (NSCLC) tumors that are 2 cm or smaller. However, it remains unclear whether NSCLC patients with squamous cell carcinoma (SCC) have comparable outcomes to those with adenocarcinoma (ADC) following sublobectomy. To that end, this study aims to compare the survival outcomes between SCC and ADC in patients with stage IA NSCLC (≤ 2 cm) who have undergone sublobectomy.

Targeting P4HA1 promotes CD8 T cell progenitor expansion toward immune memory and systemic anti-tumor immunity.

Cancer Cell

Genome Institute of Singapore, Agency for Science, Technology, and Research (A(∗)STAR), 60 Biopolis Street, Singapore; Department of Physiology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore; Cancer and Stem Cell Biology, Duke-NUS Medical School, Singapore. Electronic address:

Successful immunotherapy relies on both intratumoral and systemic immunity, which is yet to be achieved for most patients with cancer. Here, we identify P4HA1, encoding prolyl 4-hydroxylase 1, as a crucial regulator of CD8 T cell differentiation strongly upregulated in tumor-draining lymph nodes (TDLNs) and hypoxic tumor microenvironment. P4HA1 accumulates in mitochondria, disrupting the tricarboxylic acid (TCA) cycle through aberrant α-ketoglutarate and succinate metabolism, promoting mitochondria unfitness and exhaustion while suppressing progenitor expansion.
