Capsaicin exerts synergistic pro-apoptotic effects with cisplatin in TSCC through the calpain pathway via TRPV1.

Capsaicin (CAP) exerts significant anti-tumor effects on a variety of tumors, with low intrinsic toxicity. Cisplatin (DDP) is currently the first-line drug for the treatment of oral cancer; however, its clinical efficacy is impeded by chemoresistance and negligible side effects. Whether the combined use of CAP and DDP has a synergistic antitumor effect on tongue squamous cell carcinoma (TSCC) cells and its underlying mechanisms remains unclear.

Reduced syncytin-1 regulates trophoblast invasion and apoptosis in preeclampsia.

Introduction: Preeclampsia is a pregnancy-specific disorder characterized by de novo development of hypertension and proteinuria over 20 weeks gestation that has been associated with the dysfunction of trophoblasts. Current evidence suggests that syncytin-1 plays an important role in the non-fusogenic biological activity of trophoblasts, except for specific fusogenic function. However, the underlying mechanism remains unclear.

Evolutionary and immune-activating character analyses of NLR genes in algae suggest the ancient origin of plant intracellular immune receptors.

Nucleotide-binding leucine-rich repeat (NLR) proteins are crucial intracellular immune receptors in plants, responsible for detecting invading pathogens and initiating defense responses. While previous studies on the evolution and function of NLR genes were mainly limited to land plants, the evolutionary trajectory and immune-activating character of NLR genes in algae remain less explored. In this study, genome-wide NLR gene analysis was conducted on 44 chlorophyte species across seven classes and seven charophyte species across five classes.

The greater yam (), a widely cultivated and nutritious food crop, suffers from widespread yield reduction due to anthracnose caused by . Latent infection often occurs before anthracnose phenotypes can be detected, making early prevention difficult and causing significant harm to agricultural production. Through comparative genomic analysis of 60 genomes of 38 species from the genus, this study identified 17 orthologous gene groups (orthogroups) that were shared by all investigated strains but absent from all other species.

Identification and characterization of mitogen-activated protein kinase kinase 4 (MKK4) from the mud crab Scylla paramamosain in response to Vibrio alginolyticus and White Spot Syndrome Virus (WSSV).

Mitogen-activated protein kinase kinase 4 (MKK4), serves as a critical component of the mitogen-activated protein kinase signaling pathway, facilitating the direct phosphorylation and activation of the c-Jun N-terminal kinase (JNK) and p38 families of MAP kinases in response to environmental stresses. In the current research, we identified two MKK4 subtypes, namely SpMKK4-1 and SpMKK4-2, from Scylla paramamosain, followed by the analysis of their molecular characteristics and tissue distributions. The expression of SpMKK4s was induced upon WSSV and Vibrio alginolyticus challenges, and the bacteria clearance capacity and antimicrobial peptide (AMP) genes' expression upon bacterial infection were significantly decreased after knocking down SpMKK4s.

The evolution of plant NLR immune receptors and downstream signal components.

Along with the emergence of green plants on this planet one billion years ago, the nucleotide binding site leucine-rich repeat (NLR) gene family originated and diverged into at least three subclasses. Two of them, with either characterized N-terminal toll/interleukin-1 receptor (TIR) or coiled-coil (CC) domain, serve as major types of immune receptor of effector-triggered immunity (ETI) in plants, whereas the one having a N-terminal Resistance to powdery mildew8 (RPW8) domain, functions as signal transfer component to them. In this review, we briefly summarized the history of identification of diverse NLR subclasses across Viridiplantae lineages during the establishment of NLR category, and highlighted recent advances on the evolution of NLR genes and several key downstream signal components under the background of ecological adaption.
