Protein kinase A (PKA), also known as cAMP dependent protein kinase, is an essential component of many signaling pathways, many of which regulate key developmental processes. Inactive PKA is a tetrameric holoenzyme, comprised of two catalytic (PRKAC), and two regulatory subunits. Upon cAMP binding, the catalytic subunits are released and thereby activated. There are multiple isoforms of PKA catalytic subunits, but their individual roles are not well understood. In order to begin studying their roles in zebrafish development, it is first necessary to identify the spatial and temporal expression profiles for each prkac subunit. Here we evaluate the expression profiles for the four zebrafish prkacs: prkacαa, αb, βa, and βb, at key developmental time points: 24, 48 and 72 h post fertilization. We show that zebrafish prkacs are expressed throughout the developing nervous system, each showing unique expression patterns. This body of work will inform future functional studies into the roles of PKA during development.

The FIKK protein family, encompassing 21 serine-threonine protein kinases, is a distinctive cluster exclusive to the Apicomplexa phylum. Predominantly located in which is a malarial parasite, with a solitary gene identified in a distinct apicomplexan species, this family derives its nomenclature from - phenylalanine, isoleucine, lysine, lysine (FIKK), a conserved amino acid motif. Integral to the parasite's life cycle and consequential to malaria pathogenesis, the absence of orthologous proteins in eukaryotic organisms designates it as a promising antimalarial drug target.

RIG-I and MDA5 are members of RIG-I-like receptors (RLRs) that detect viral RNA within the cytoplasm and subsequently initiate antiviral immune responses. Necroptosis is a form of programmed cell death (PCD) executed by mixed lineage kinase domain-like (MLKL), which, upon phosphorylation by receptor-interacting protein kinase 3 (RIPK3), causes necrotic cell death. To date, no link between RLRs and necroptosis has been observed during bacterial infection.

Background: Cardiovascular biomarkers are crucial for monitoring cancer therapy-related cardiac toxicity, but the effects on early stage are still inadequate. To screen biomarkers in patients with breast cancer who receive anthracycline-containing chemotherapy, we studied the behavior of six biomarkers during chemotherapy and their association with chemotherapy-related cardiac toxicity.
Methods: In a prospective cohort of 73 patients treated with anthracycline-containing chemotherapy, soluble suppression of tumorigenicity 2 (sST2), high-sensitivity cardiac troponin T, N-terminal pro-B-type natriuretic peptide (NT-proBNP), myoglobin, creatine kinase isoenzyme MB, and heart-fatty acid binding protein were measured at baseline, during chemotherapy cycle (C1-C6).

Background: Heredity and epigenetics affect the pathogenesis of microscopic polyangiitis (MPA). Tyrosine kinase 2 (TYK2) polymorphisms (rs2304256C > A, rs280519A > G, and rs12720270G > A) may be potential protective factors against anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Current research suggests that TYK2 is associated with various autoimmune diseases; however, no study has examined the relationship between TYK2 polymorphisms and AAV.

Introduction: Largemouth bass is an economically important farmed freshwater fish species that has delicious meat, no intermuscular thorns, and rapid growth rates. However, the molecular regulatory mechanisms underlying the different growth and developmental stages of this fish have not been reported.
Methods: In this study, we performed histological and transcriptomic analyses on the brain and dorsal muscles of largemouth bass at different growth periods.
