Summary: The X-linked form of Kallmann syndrome is caused by mutations in the ANOS1 gene, resulting in hypogonadotropic hypogonadism and anosmia. This study reveals that anosmin 1 can enhance the activation of the PK2/PKR2 pathway and modulate its biological effects. The N-terminal region of anosmin 1 interacts with PKR2, and the whey acidic protein domain is necessary for this modulatory activity, while the cysteine-rich and FnIII.1 domains may assist in binding to PKR2 and regulating receptor activation by PK2.

Summary: Inflammation plays a crucial role in tumor progression. Prokineticin 2 is involved in tumor growth, angiogenesis, and metastasis. In addition to its function as an angiogenic factor and a mediator of immune cell migration, prokineticin 2 also suppresses tumor cell apoptosis, promotes their proliferation and movements necessary for metastasis. It is also associated with tumor pain and resistance responses, and may serve as a potential prognostic tumor biomarker.

Summary: The Prokineticin family, specifically Prokineticin 1 and Bv8/Prokineticin 2 (PROK2), interact with G protein-coupled receptors to regulate various biological functions in the central nervous system. Pathological insults can increase PROK2 expression levels and potentially contribute to neurodegenerative diseases. Despite documented physiological effects, the role of PROK2 and its receptors in neuropathological conditions remains unclear.

Summary: This study outlines the dynamics of the prokineticin-2 pathway in relation to the clinical-pathological features of Parkinson's disease by examining olfactory neurons of patients. The results show that prokineticin-2 expression is increased in Parkinson's disease and is directly correlated with the severity of motor symptoms. Additionally, the accumulation of oligomeric alpha-synuclein is associated with prokineticin-2 protein levels. These findings support prokineticin-2 as a potential target for Parkinson's disease and validate the use of olfactory neurons to reflect pathological changes of the disease.

Summary: This study investigated the role of Prokineticin 2 (PK2) in bacterial pneumonia. The levels of PK2 were found to be decreased in patients with pneumonia compared to healthy controls, and even lower in patients with severe pneumonia. Administering recombinant PK2 in a mouse model of bacterial pneumonia alleviated lung injury, improved survival, and enhanced the host's bacterial clearance capacity. PK2 was shown to enhance the chemotaxis, phagocytosis, and killing ability of macrophages.

Summary: Prokineticin 1 plays a pleiotropic role in trophoblast function during implantation and early placentation, with its signaling pathway regulating key functions such as cell proliferation and adhesion. The study also identified the involvement of various signaling pathways, including MAPK, PI3K/AKT/mTOR, and cAMP, in mediating the effects of PROK1 in trophoblasts. The findings suggest that PROK1 has a significant impact on trophoblast development and function in the early stages of pregnancy.

Summary: FOSL1 is a key player in regulating the proneural to mesenchymal transition (PMT) in glioblastoma stem cells (GSCs). It promotes the ionizing radiation-induced PMT and radioresistance of Proneural GSCs. Mechanistically, FOSL1 induces PMT by promoting UBC9-dependent CYLD SUMOylation and subsequent NF-kappa B activation. Therapeutic targeting of FOSL1 holds promise to attenuate molecular subtype switching in glioblastoma patients.

Summary: The pulse response expression of the non-line-of-sight underwater laser channel is derived based on the binomial Henyey-Greenstein scattering phase function, considering the forward and backward effects. The effectiveness of the established underwater photon transmission channel model is simulated and verified, showing better fitting effects in coastal waters. The pulse-broadening factor is higher in coastal waters compared to harbor waters, and the time-domain broadening effect of laser pulse transmission is significant in harbor waters, particularly influenced by front scattering when the asymmetry factor is large.

Summary: The expression of BST2 and MMP2 is significantly downregulated in preeclampsia. Overexpression of BST2 can upregulate MMP2 expression and enhance the migration and invasion capacity of trophoblast cells. Knockdown of BST2 or MMP2 has opposite effects. These results suggest that the downregulation of BST2 may play a role in the pathogenesis of preeclampsia.

Summary: Chronic kidney disease (CKD) is an independent risk factor for peripheral artery disease (PAD). The role of uremic solutes retained in CKD patients in PAD is not well understood. This study reveals that tryptophan-derived uremic solutes inhibit beta-catenin, a key regulator of angiogenesis, in several cell types including endothelial cells. These solutes downregulate beta-catenin through the aryl hydrocarbon receptor (AHR). CKD mouse models show reduced beta-catenin and blood vessel density in ischemic limbs, which correlates with increased levels of uremic solutes and AHR activity. In a cohort of PAD patients, higher plasma levels of tryptophan metabolites and increased AHR-inducing activity in endothelial cells are associated with an increased risk of adverse limb events. Targeting the tryptophan metabolite/AHR/beta-catenin axis may provide new therapeutic strategies for PAD in CKD patients.

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.

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.

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.

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.
