- Heat shock proteins (HSPs) are essential for cellular homeostasis and thermal adaptation, yet their interaction networks and regulatory mechanisms under high temperature stress remain largely unexplored in aquatic organisms. Here, the expression profiles of HSPs in Urechis unicinctus under high temperature stress were systematically characterized. Among 85 identified HSPs, a member of the HSP70 family, HSP70CA2, was selected for further study due to its sustained and significant differential expression. Sequence analysis revealed that HSP70CA2 has an open reading frame (ORF) of 1917 bp, encoding a 638 amino acid protein. Western blotting confirmed a rapid and significant increase in HSP70CA2 protein levels in both body wall and midgut tissues during early high temperature stress, indicating its active involvement in the initial stress response. Crucially, five novel interacting proteins of HSP70CA2 were screened and identified as cytoskeletal (CIFP), membrane repair (ANXA7), ER-associated (CRT-like), and chaperone (HSP90A1, HSPA8) factors by pull-down assays coupled with LC-MS. These interactions were validated by point to point yeast two-hybrid assays. Our findings suggest that HSP70CA2 acts as an early chaperone related responder associated with cytoskeletal maintenance, membrane repair, and protein folding processes during the acute heat shock response in U. unicinctus. This study provides new evidence for the involvement of a single HSP70 member in multiple cellular protective processes in an aquatic invertebrate, offering fundamental insights into thermal stress adaptation and a potential target for thermotolerance breeding. - Source: PubMed

Lin DaweiFeng YuxinJiang WenwenLu YingZhang WenqingZhang LongZhang ZhifengMa Yubin - Despite significant advancements in CRISPR/Cas-based genome editing technology over the past decade, achieving simultaneous homozygous gene editing at multiple targets in primary cells remains a major challenge. In this study, we developed and constructed a CRISPR multi-gene targeting system that integrates episomal vectors with tRNA-sgRNA array technology. This approach leverages scaffold/matrix attachment region (S/MAR) sequences to enable sustained episomal expression of both Cas9 and single-guide RNAs (sgRNAs) without genomic integration, thereby enhancing gene editing efficiency. For simultaneous editing of multiple loci, we used the tRNA-sgRNA architecture to process multiple sgRNAs from a single vector. Using this system in porcine fetal fibroblasts, we achieved concurrent editing of six genes, namely , , , , , and , in individual cells. These edited cells supported normal development following somatic cell nuclear transfer, yielding blastocysts with unaltered developmental competence. Collectively, our findings establish a framework for the application of CRISPR/Cas9 in gene-edited pigs, facilitating the generation of multi-gene-edited animals for biomedical and agricultural applications. - Source: PubMed

Colon tissues from CD patients, including inflamed and uninflamed tissues, were analyzed to assess ANXA7 expression. The biological functions of ANXA7 were studied in vitro using LPS/ATP-stimulated NCM460 cells, employing ANXA7 knockdown and overexpression experiments. Protein-protein interactions were examined using co-immunoprecipitation (Co-IP) and mass spectrometry. The regulatory role of RNF168 in ANXA7 degradation was explored through Co-IP and ubiquitination assays. The effects of RNF168 and ANXA7 on autophagy and NLRP3 inflammasome-induced pyroptosis were assessed. In vivo experiments were conducted using IL-10 knockout (KO) mice, RNF168 mice with TNBS-induced colitis, and organoids to investigate the therapeutic potential of RNF168 and ANXA7 manipulation. ANXA7 expression was significantly reduced in inflamed tissues and correlated with CD-related inflammatory markers. RNF168 promoted the ubiquitination and degradation of ANXA7, thereby suppressing autophagy and inducing NLRP3 inflammasome-mediated pyroptosis. The in vitro and in vivo biological functions of sh-RNF168 were rescued by sh-ANXA7. ELK1 was identified as a key transcription factor regulating RNF168 expression, linking transcriptional regulation with inflammation and disease progression. Our findings suggest a mechanistic model where ELK1 upregulates RNF168, leading to ANXA7 degradation, suppression of autophagy, and enhanced pyroptosis, thereby promoting CD progression and intestinal barrier disruption. Targeting the RNF168-ANXA7 axis offers a potential therapeutic strategy for CD. - Source: PubMed

Wang HonggangLiu YujunJiang WenliangJi YunCheng ShaoqiCheng ChaoXu ZiweiZhang ChangheSun JingZhao Jie - Directed axonal trafficking of mRNA via ribonucleoprotein (RNP) complexes is essential for neuronal function and survival. However, mechanisms governing retrograde RNP transport remain poorly understood. Here, we reveal that Annexin A7 (ANXA7) promotes the recruitment of aggregation-prone T-cell intracellular antigen 1 (TIA1)-containing RNPs to cytoplasmic dynein, enabling their retrograde trafficking to the soma for degradation. Both persistent and transient Ca²⁺ elevation disrupted this function of ANXA7, leading to the detachment of TIA1 granules from dynein, impairing their transport, and subsequently triggering pathological TIA1 aggregation within axons. Similarly, ANXA7 knockdown decouples TIA1 granules from dynein, preventing their transport and inducing pathological aggregation of TIA1, which culminates in axonopathy and neurodegeneration both in vitro and in vivo. Conversely, ANXA7 overexpression reinforces trafficking and counteracts aberrant aggregation of TIA1-containing RNPs in axons. We describe here a Ca -regulated mechanism which modulates retrograde axonal trafficking of RNPs and prevents the formation of pathological aggregates in axons. - Source: PubMed
