- BACKGROUND: Antler is an important economic trait of sika deer (Cervus nippon), capable of rapid growth without signs of tumorigenesis. However, the molecular mechanisms underlying its unique growth pattern remain poorly understood. This study conducted a combined transcriptomic, proteomic, metabolomic and single-cell transcriptomic analysis of tip mesenchyme of antler at three key growth stages, early, middle, and late growth (EG, MG, LG), to explore the molecular characteristics during antler growth. RESULTS: Active post-transcriptional and post-translational regulation likely occurred during antler growth, as characterized by significant alternative splicing (AS) events and significant enrichment of post-transcriptional and post-translational regulatory functions at the protein level. The multi-level regulatory network constructed based on differentially expressed genes, proteins, and metabolites (DEGs, DEPs, DEMs) indicated continuous and extensive metabolic reprogramming in the glycerophospholipid metabolism pathway. PLA2G3, MBOAT2, LPCAT3, DGKI, and EPT1 were positioned at core nodes within this pathway. The qRT-PCR confirmed that these genes were predominantly expressed in MG, suggesting their role as crucial candidate genes involved in regulating the metabolic reprogramming. Analysis of single-cell transcriptomic data revealed that the MBOAT2, LPCAT3, DGKI, and EPT1 genes were expressed in key cell types such as chondroblasts, chondrocytes, osteoblasts, and mesenchymal cells. CONCLUSIONS: Integrated multi-omics analyses indicated that the rapid growth of antlers is closely associated with continuous metabolic reprogramming, involving multi-layered regulation of glycerophospholipid metabolism. This study established a foundational multi-omics resource, providing new perspectives for elucidating the molecular mechanisms of antler growth and for subsequent functional studies, while also offering novel insights for research on organ and tissue growth in animals. - Source: PubMed

Xing HaihuaZhao XunwuWang QianghuiMa YukaiGuo XingjianZhang YujieJiang QiLi Heping - Microplastics and nanoplastics are commonly found in our everyday environments. So far, microplastics and nanoplastics have been detected in various tissues and bodily fluids, including hair, sputum, digestive tissue, lungs, blood, placental and endometrial tissue. Although some studies indicate that microplastics and nanoplastics can promote tumor development, their impact on endometrial cancer (EC) remains unclear. In this study, we examined the effect of polystyrene nanoplastics (PS-NPs) on EC development and explored the underlying pathogenic mechanisms. We observed the uptake and accumulation of PS-NPs in HEC-1B cells and EC organoids. Through cell and organoid experiments as well as mouse models, we demonstrated that PS-NP exposure can accelerate EC progression in vitro and in vivo. Next, through transcriptomic sequencing and targeted metabolomic sequencing, We found that adenosine 5'-monophosphate-activated protein kinase (AMPK) can activate ACSS2 and promote its nuclear translocation. The nuclear entry of ACSS2 is associated with increased levels of H3K9 acetylation, which may be a potential mechanism through which it regulates PLA2G3 expression. PLA2G3 mRNA levels are upregulated, increasing the production of arachidonic acid (AA), and ultimately leads to the epithelial-mesenchymal transition (EMT) in EC cells. The relevant molecular markers in this study can provide new strategies for early warning and targeted intervention, reducing the potential impact of PS-NPs on EC. - Source: PubMed

Huang XiangchunXu LiWang JielinCheng JiachenYuan JingLiu XinLarionova IrinaKzhyshkowska JuliaChen ShuoZhao Yang - Cervical cancer, in which cervical squamous cell carcinoma (CSCC) accounts for 60-70% of cases, has a poor prognosis and poses a significant health threat to global patients. Lipid metabolism reprogramming is a key driver of tumor progression and tumor microenvironment (TME) regulation, making it a promising target for improving the efficacy of immunotherapy. This study aimed to construct a lipid metabolism prognostic signature (LMPS) in CSCC and identify key genes involved in tumor progression. - Source: PubMed

Bai GaigaiChen FanghuaQiu JunjunHua Keqin - The study examined the induction and mechanism of bone regeneration facilitated by the P24-loaded Gelatin-Hydroxyapatite-Tricalcium Phosphate (Gelatin-HA-TCP (P24)) scaffold. The prepared Gelatin-HA-TCP (P24) scaffold was employed to treat human bone marrow mesenchymal stem cells (hBMSCs) and human umbilical vein endothelial cells (HUVECs). Various assays were conducted to assess the impact of the Gelatin-HA-TCP (P24) scaffold on the osteogenic differentiation of hBMSCs and angiogenesis in HUVECs. For mechanistic investigations, hBMSCs were exposed to both the Gelatin-HA-TCP (P24) scaffold and the ERK inhibitor SCH772984. A rat cranial bone defect model was treated through the implantation of the Gelatin-HA-TCP (P24) scaffold. Micro-computed tomography, histological staining, and immunofluorescence techniques were utilized to evaluate the effect of the Gelatin-HA-TCP (P24) scaffold on cranial bone regeneration. Osteogenic differentiation of hBMSCs was facilitated by the Gelatin-HA-TCP (P24) scaffold, as evidenced by increased ALP activity, enhanced Alizarin Red S staining, and upregulated RUNX2, OSX, OCN, and BMP2. Angiogenesis in HUVECs was induced, as demonstrated by improved migration, tube formation, and upregulated CD31. However, the ability of the Gelatin-HA-TCP (P24) scaffold to promote osteogenic differentiation in hBMSCs was counteracted by SCH772984. In the rat cranial bone defect model, implantation of the Gelatin-HA-TCP (P24) scaffold reduced the bone defect area, increased the bone volume/tissue volume ratio, enhanced bone regeneration, decreased bone fibrosis, and upregulated CD31, RUNX2, and BMP2 in bone tissues. Therefore, the Gelatin-HA-TCP (P24) scaffold enhances the osteogenic differentiation of hBMSCs and promotes bone regeneration in cranial bone defects by activating the ERK/ELK1/PLA2G3 pathway. It has potential for bone regeneration therapies. - Source: PubMed
