Biliary tract carcinoma (BTC) is a group of malignant tumors that originate in the digestive system and occurs with a high incidence in China. Few consistent and comparable assessments of BTC disease burden have been conducted at national or subnational levels, and little is known about the demographic, temporal, and geographic patterns of epidemiological characteristics and disease burden of BTC in China. The incidence, mortality, disability-adjusted life-years (DALYs), years of life lost (YLLs) due to premature death and years lived with disability (YLDs) of BTC were comprehensively examined by age, sex, and calendar year in the Chinese population, using the methodological framework and analytical strategies used for the 2021 Global Burden of Disease study.

Article Synopsis
  • Surgical interventions like tension-free vaginal tape (TVT) are more effective than non-surgical methods for treating stress urinary incontinence (SUI), and this study compares two types of TVT: the obturator (TVT-O) and the abdominal (TVT-A).
  • A total of 96 patients underwent these procedures, and both groups showed similar success rates in improving SUI during one-year (95.9% for TVT-O, 95.8% for TVT-A) and five-year (87.8% for TVT-O, 93.6% for TVT-A) follow-ups.
  • The results indicate that both TVT-A and TVT-O have comparable effectiveness and low complication rates

Induction of programmed cell death (PCD) is a key cytotoxic effect of anticancer therapies. PCD is not confined to caspase-dependent apoptosis, but includes necroptosis, a regulated form of necrotic cell death controlled by receptor-interacting protein (RIP) kinases 1 and 3, and mixed lineage kinase domain-like (MLKL) pseudokinase. Necroptosis functions as a defense mechanism against oncogenic mutations and pathogens and can be induced by a variety of anticancer agents.

Kernel size and plant architecture play important roles in kernel yield in rice. Cloning and functional study of genes related to kernel size and plant architecture are of great significance for breeding high-yield rice. Using the single-segment substitution lines which developed with as a donor parent and an elite cultivar Huajingxian74 (HJX74) as a recipient parent, we identified a novel QTL (quantitative trait locus), named , which controls kernel size and plant architecture.

Neurodegenerative diseases are characterized by chronic neuroinflammation and may perpetuate ongoing fibrotic reactions within the central nervous system. Unfortunately, there is no therapeutic available that treats neurodegenerative inflammation and its sequelae. Here we utilize cromolyn, a mast cell inhibitor with anti-inflammatory capabilities, and its fluorinated analogue F-cromolyn to study fibrosis-related protein regulation and secretion downstream of neuroinflammation and their ability to promote microglial phagocytosis and neurite outgrowth.

Use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with reduced risk of colorectal cancer (CRC). However, the mechanism by which NSAIDs suppress colorectal tumorigenesis remains unclear. We previously showed that NSAIDs selectively kill emerging tumor cells via death receptor (DR) signaling and a synthetic lethal interaction mediated by the proapoptotic Bcl-2 family protein BID.

Cancer therapies kill tumors either directly or indirectly by evoking immune responses and have been combined with varying levels of success. Here, we describe a paradigm to control cancer growth that is based on both direct tumor killing and the triggering of protective immunity. Genetic ablation of serine protease inhibitor SerpinB9 (Sb9) results in the death of tumor cells in a granzyme B (GrB)-dependent manner.

The enhancement of drug efflux caused by ATP-binding cassette (ABC) transporters (including ABCG2 and ABCB1) overexpression is an important factor for multidrug resistance (MDR) in cancers. After testing the reversal activities of 19 chalcone and bis-chalcone derivatives on MDR cancer cell lines, we found that non-basic chalcone CYB-2 exhibited the most potent reversal activities against both ABCG2- and ABCB1-mediated MDR. The mechanistic studies show that this compound can increase the accumulation of anticancer drugs in both ABCG2- and ABCB1-overexpressing cancer cell lines, resulting from the blocked efflux function of the MDR cancer cell lines.

Ko143, a potent ABCG2 inhibitor that reverses multidrug resistance in cancer, cannot be used clinically due to its unsuitable metabolic stability. We identified benzoyl indoles as reversal agents that reversed ABCG2-mediated multidrug resistance (MDR), with synthetic tractability and enhanced metabolic stability compared to Ko143. Bisbenzoyl indole 2 and monobenzoyl indole 8 significantly increased the accumulation of mitoxantrone (MX) in ABCG2-overexpressing NCI-H460/MX20 cells, and sensitized NCI-H460/MX20 cells to mitoxantrone.

Overexpression of breast cancer resistance protein (BCRP) has been shown to produce multidrug resistance (MDR) in colon cancer, leading to major obstacles for chemotherapy. In this study, we evaluated the effect of regorafenib, an oral multi-kinase inhibitor, in inhibiting BCRP-mediated MDR in silico, in vitro and in vivo. We found that regorafenib significantly sensitized MDR colon cancer cells to BCRP substrates by increasing their intracellular accumulation.

Emerging evidence suggests that the clinical success of conventional chemotherapy is not solely attributed to tumor cell toxicity, but also results from the restoration of immunosurveillance, which has been largely neglected in the past preclinical and clinical research. Antitumor immune response can be primed by immunogenic cell death (ICD), a type of cell death characterized by cell-surface translocation of calreticulin (CRT), extracellular release of ATP and high mobility group box 1 (HMGB1), and stimulation of type I interferon (IFN) responses. Here we summarize recent studies showing conventional chemotherapeutics as ICD inducers, which are capable of modulating tumor infiltrating lymphocytes (TILs) and reactivating antitumor immunity within an immuno-suppressive microenvironment.
