Article Abstract
Background: Tartrate-resistant acid phosphatase (ACP5) has been implicated in the progression of most malignant tumors, but its role in pancreatic cancer (PC) remained unclear. Thus, this study aimed to elucidate the role and function of ACP5 in PC progression.
Methods: The expression of ACP5 in PC samples was assessed via R programming, TNM plot, and Gene Expression Profiling Interactive Analysis (GEPIA). Western blotting and immunohistochemistry (IHC) were performed to detect ACP5 expression in cells and tissues. The correlation between ACP5 and methylation was analyzed using the University of ALabama at Birmingham Cancer data analysis Portal (UALCAN) and cBio Cancer Genomics Portal (cBioPortal). The Database for Annotation, Visualization and Integrated Discovery (DAVID) and Gene Set Enrichment Analysis (GSEA) were used for the enrichment of ACP5 in PC. Subsequently, Cell Counting Kit-8 (CCK8), clonogenic, and wound healing assays were used to investigate the role of ACP5 in PC. Finally, Tumor Immune Estimation Resource (TIMER) and R programming was utilized in evaluating the association between ACP5 and immune cell infiltration in PC.
Results: The analyses confirmed that ACP5 was highly expressed in PC samples. According to UALCAN and cBioPortal analysis, ACP5 expression, and methylation levels were negatively correlated in PC. The enrichment analysis also revealed that ACP5 was enriched in the proliferation and migration pathways. Meanwhile, ACP5 knockout reduced PC cell proliferation and migration and impaired the cells' independent viability. This gene also positively correlated with immune cell infiltration in PC, particularly regulatory T cells (Tregs).
Conclusion: ACP5 is crucial for proliferation, migration, and immune cell infiltration in PC. Therefore, ACP5 may be a valuable target for future PC treatment.

Spondyloenchondrodysplasia with immune dysregulation (SPENCDI) is autosomal recessive hereditary disease caused by tartrate resistant acid phosphatase 5 (ACP5) mutations. The symptoms mainly involve the bone, immune system and nervous system, and the typical manifestations are short stature, abnormal development of long diaphyseal epiphysis, flat vertebra, and prone to various autoimmune diseases. Some children have muscle spasm, mild mental retardation, intracranial calcification and other neurological manifestations.

Rheumatoid arthritis (RA) and other inflammatory arthritis are systemic diseases that primarily affect the joints, characterized by synovial inflammation and progressive cartilage and bone degradation. The temporomandibular joint (TMJ) is reported to be involved in over 50% of RA cases, often leading to severe jaw pain and compromised oral function. Despite its prevalence, TMJ involvement is often underestimated, and its cellular and molecular mechanisms remain poorly understood.

The translocator protein (TSPO) is a mitochondrial outer membrane protein that is constitutively expressed in various immune cells, including macrophages, dendritic cells, T cells, and B cells. TSPO has been implicated in mitochondrial function and immune regulation, particularly in macrophages, which are also osteoclast precursors. However, its role in osteoclast differentiation remains unclear.

The Junggar Bactrian camel, a primitive indigenous breed in China, exhibits low reproductive efficiency under natural grazing conditions. This is partly attributed to the development of the epididymis and the quality of semen, both of which directly affect reproductive performance. The epididymis is a key male reproductive organ responsible for sperm storage and transport.

Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related mortality, with immunotherapy proving effective only in a subset of patients, highlighting the urgent need for improved biomarkers and therapeutic targets. This study explored regulatory T cell (Treg) metabolism-related genes in NSCLC and established a seven-gene prognostic signature (TIMP1, BIRC3, G0S2, PRKCB, PDE4B, CD52, and ACP5) through multi-omics analysis. The model stratified patients into high- and low-risk groups exhibiting distinct immune profiles and drug sensitivities.
