Summary: The study aimed to investigate the mechanical and electrophysiological effects of emodin on BK channels in rat interlobar renal artery smooth muscle cells (IRASMCs). The results showed that emodin induced vasorelaxation and enhanced outward currents in a concentration-dependent manner. These effects were mediated through the activation of BK channels.

Summary: The study demonstrates the crucial role of the interaction between the neuronal protein hevin and the vesicular protein calcyon in synaptic reorganization after brain injury. The regulated expression and interaction between hevin and calcyon were confirmed in mouse models of traumatic brain injury and patients with chronic traumatic encephalopathy, providing direct evidence for their causal relationship in synaptic reorganization. Neuron-glia interactions between hevin and calcyon can be utilized to modulate synaptic reorganization in various neurological conditions.

Summary: The standard model for Ca2+ oscillations in insulin-secreting pancreatic 13 cells relies on voltage-activated Ca2+ channels for Ca2+ entry. These channels work together with ATP-dependent K+ channels to regulate the secretion of insulin in response to the metabolic state of the cells. However, an alternative model proposes that calcium-induced calcium release from the endoplasmic reticulum is the key driver of islet oscillations. This study shows that the alternative model is incompatible with established experimental data and that the standard model provides a better explanation for the new observations.

Summary: PKC inhibitors stimulate Ca2+ release from internal stores by increasing SR Ca2+ leak mediated by translocon activation. This increased leak does not deplete the Ca2+ store, but rather compensates by increasing SERCA pump activity, leading to a new steady-state level. This change also results in increased activity of high conductance, Ca2+-sensitive potassium channels.

Summary: In fruit fly larvae, the IP3/Ca2+ signals in specific interneurons drive the expression of Set2 gene, essential for pupariation in the absence of dietary protein. This signal-controlled expression of Set2 upregulates key Ca2+-signaling genes through a positive-feedback loop, regulating gene expression for the transition from larval to pupal stages.

Summary: Ettringite-accelerated binders, composed of CAC-PC-C$ and CSA-PC-C$, are widely used for indoor applications due to their rapid setting, early strength gain, and shrinkage compensation properties. However, their stability in outdoor exposure conditions remains uncertain. This critical review aims to analyze current research and identify knowledge gaps in order to determine factors that promote or deter ettringite stability.

Summary: In this study, the researchers explored the role of DHX38 in NSCLC and its underlying molecular mechanism. They found that DHX38 was overexpressed in NSCLC and patients with high DHX38 expression had poor prognosis. DHX38 promoted cell proliferation, migration, and invasion in NSCLC and activated the MAPK pathway. The researchers also identified G3BP1 as a target protein that interacted with DHX38 and showed that DHX38 regulated the expression of G3BP1. Silencing G3BP1 reversed the effects of DHX38 overexpression on tumor cell proliferation, migration, and invasion and inhibited the MAPK pathway activation.

Summary: Microenvironment signals have a significant impact on cell fate and tissue homeostasis. Understanding how different microenvironment factors regulate cellular phenotype has been challenging. In this study, a high-throughput microenvironment microarray was used to identify factors that support the proliferation and maintenance of primary human mammary luminal epithelial cells. Multiple factors that modulate luminal cell number were identified and their effects were confirmed using RNA sequencing and cell-based functional studies. Hepatocyte growth factor (HGF) was found to be robust to individual variation and played a role in expanding luminal cells. Our approach demonstrates the power of high-dimensional cell-based approaches in dissecting microenvironmental signals.

Summary: miR-29c-3p is overexpressed in benign and malignant ovarian carcinoma and is associated with poor prognosis. Its overexpression modulates tumorigenesis in ovarian cancer cells, including epithelial-mesenchymal transition, proliferation, migration, and invasion, through the regulation of DNMT3A, TET1, and HBP1. miR-29c-3p may serve as a potential biomarker for clinical diagnosis or co-diagnosis of ovarian carcinoma.

Summary: This study investigated the role of transcription factor FoxO1 in facet joint osteoarthritis (FJOA) and found that FoxO1 deletion led to severe osteoarthritic changes. Transcriptome sequencing and bioinformatics analysis identified differentially expressed genes (DEGs) and potential key contributors to FJOA. Additionally, over-expression of certain genes and inhibition of others were shown to counteract the impairments caused by FoxO1 deletion in chondrocyte migration and extracellular matrix synthesis. These findings help unravel the molecular mechanisms underlying FJOA and open up promising therapeutic avenues for its treatment.

Summary: Cholesterol biosynthesis and metabolism play critical roles in tumor development and microenvironmental conditions. Squalene Epoxidase (SQLE), the second rate-limiting enzyme in cholesterol synthesis, is found to be uniquely expressed in various cancers, and its expression level is closely associated with tumor mutation burden and microsatellite instability. SQLE expression is negatively correlated with immune cell infiltration. Inhibition of SQLE alters the immune response in the tumor microenvironment. Furthermore, protein metabolism and translation are identified as main binding factors with SQLE.

Summary: Circular RNAs (circRNAs) are non-coding RNAs that play a role in the regulation of various cancers, including osteosarcoma (OS). This study identified circSATB2 as a highly expressed circRNA in OS tissues and cell lines, and demonstrated its involvement in promoting OS proliferation and migration. Mechanistically, circSATB2 was found to regulate the progression of OS by sponging miR-661 and FUS to regulate ZNFX1 mRNA. These findings suggest that circSATB2 could serve as a prognostic marker and therapeutic target for osteosarcoma.

Summary: This study found that extracellular vesicles released by induced pluripotent stem cells can reduce inflammatory cell infiltration, increase saliva volume, and decrease the production of antibodies associated with Sjogren's syndrome in a mouse model. The let-7 family in these vesicles may suppress the expression of TLR4 and NF-kappa B, which leads to the inhibition of pro-inflammatory cytokine production through the MAPK pathway.

Summary: Recent evidence suggests that cAMP signaling within the primary cilium plays a crucial role in promoting adipogenic differentiation of 3T3-L1 preadipocytes. In this study, the researchers identified the specific cAMP phosphodiesterases expressed by these cells and found that inhibition of PDE4 promotes FFAR4-mediated adipogenesis. This work could potentially lead to the discovery of more targeted therapeutic approaches for controlling adipogenesis and differentiation of other stem cells.

Summary: Bladder cancer, the most common malignant tumor in the urinary system, is associated with significantly up-regulated expression of P3H4, which is regulated by METTL3 and plays a crucial role in the proliferation, metastasis, and EMT progression of bladder cancer. Targeting this METTL3-P3H4 pathway may serve as a potential therapeutic strategy for bladder cancer.
