Ankylosing Spondylitis (AS) and Systemic Sclerosis (SSc) are both autoimmune diseases, albeit with distinct anatomical targets. AS primarily affects the spine and sacroiliac joints, triggering inflammation and eventual fusion of the vertebrae. SSc predominantly impacts the skin and connective tissues, leading to skin fibrosis, thickening, and potential damage to vital organs such as the lungs, heart, and kidneys. Despite their differing anatomical manifestations, inflammation serves as a pivotal factor in both conditions. Exploring the causes of the different pathogenesis of inflammation in AS and SSc could provide new insights into their treatment. We selected RNA-seq profiles of peripheral blood mononuclear cells (PBMCs) from the GEO datasets GSE73754 and GSE19617. DEGs were identified using the Limma R package with an adjusted p-value cutoff of < 0.05. Gene Ontology pathway analysis, SVM recursive feature elimination, and Gene Set Enrichment Analysis (GSEA) were conducted to analyze the DEGs. CIBERSORT was applied to estimate immune cell composition and its correlation with hub genes. Single-cell RNA sequencing data from peripheral blood mononuclear cells in the GSE194315 dataset were included to support differential expression analysis and biomarker identification. Additionally, single-cell RNA sequencing data from bone marrow blood samples were utilized to further validate these findings, offering complementary insights into biomarker expression across distinct sample types. A total of 762 DEGs were identified between AS patients and controls, and 441 DEGs between SSc patients and controls. Both conditions showed enrichment in the Natural killer cell mediated cytotoxicity pathway. ZSWIM6 and CCL3L3 were identified as potential biomarkers in AS and SSc, with significant diagnostic capabilities demonstrated by ROC analysis. Correlation analysis revealed associations between these biomarkers and specific immune cell types. The study utilizing ZSWIM6 and CCL3L3 as potential biomarkers provides deep insights into the distinct molecular mechanisms of SSc and AS. These findings lay the foundation for future research on targeted therapies and enhance our understanding of immune cell interactions in these autoimmune diseases.

AKT signaling pathway is a critical intracellular signaling pathway involved in regulating various cellular processes, including cell proliferation, cell survival, cell migration and metabolism. Cancer cells have a propensity to alter the expression of pro- and anti-angiogenic signals to activate the angiogenic switch. Aberrant overexpression of AKT pathway is associated with various types of cancers and enables the migration and invasion of tumor cells to neighboring tissues. Garcinol, a natural benzophenone, displays potent anticancer potential against various cancer cells, but its mechanism of action in inducing apoptosis remains unclear. The present study aimed to unveil the mechanism of action of garcinol in inducing apoptosis in rhabdomyosarcoma cells. Garcinol inhibited cell proliferation, reduced the viability of cancer cells, diminished colony formation, and mitigated the migratory capabilities of Rh cells. In vitro analysis of garcinol unveiled potent anticancer and anti-metastatic activity, with an IC₅₀ ranging from 5.32 to 16.28 against Rh cell lines, as demonstrated by MTT assay. Garcinol actuates apoptosis by triggering mitotic arrest (G2/M phase arrest) in Rh cell lines and alters the expression of pro-apoptotic and anti-apoptotic proteins to trigger efficient apoptosis in cancer cells.
