Cancer-associated fibroblasts undergoing neoadjuvant chemotherapy suppress rectal cancer revealed by single-cell and spatial transcriptomics

Cell Reports Medicine, Journal Year: 2023, Volume and Issue: 4(10), P. 101231 - 101231

Neoadjuvant chemotherapy (NAC) for rectal cancer (RC) shows promising clinical response. The modulation of the tumor microenvironment (TME) by NAC and its association with therapeutic response remain unclear. Here, we use single-cell RNA sequencing spatial transcriptome to examine cell dynamics in 29 patients RC, who are sampled pairwise before after treatment. We construct a high-resolution cellular dynamic landscape remodeled their associations markedly reshapes populations cancer-associated fibroblasts (CAFs), which is strongly associated CAF subsets regulate TME through recruitment crosstalk activate immunity suppress progression multiple cytokines, including CXCL12, SLIT2, DCN. In contrast, epithelial-mesenchymal transition malignant cells upregulated CAF_FAP MIR4435-2HG induction, resulting worse outcomes. Our study demonstrates that inhibits modulates remodeling CAFs.

Effect of the gut microbiome, plasma metabolome, peripheral cells, and inflammatory cytokines on obesity: a bidirectional two-sample Mendelian randomization study and mediation analysis

Frontiers in Immunology, Journal Year: 2024, Volume and Issue: 15

Published: March 15, 2024

Background Obesity is a metabolic and chronic inflammatory disease involving genetic environmental factors. This study aimed to investigate the causal relationship among gut microbiota abundance, plasma metabolomics, peripheral cell (blood immune cell) counts, cytokines, obesity. Methods Summary statistics of 191 traits (N = 18,340), 1,400 metabolite 8,299), 128 counts cells, N 408,112; 3,757), 41 cytokine 8,293), 6 obesity were obtained from publicly available genome-wide association studies. Two-sample Mendelian randomization (MR) analysis was applied infer links using inverse variance-weighted, maximum likelihood, MR-Egger, weighted median, mode, Wald ratio methods. Several sensitivity analyses also utilized ensure reliable MR results. Finally, we used mediation identify pathway mediated by metabolites, cytokines. Results revealed effect 44 taxa, 281 27 8 cytokines on Among them, five shared taxa belonged phylum Actinobacteria , order Bifidobacteriales family Bifidobacteriaceae genus Lachnospiraceae UCG008, species Eubacterium nodatum group. Furthermore, screened 42 7 1 cytokine. Based known observed that pathways D-arginine, D-ornithine, linoleic acid, glycerophospholipid metabolism closely related 20 relationships, including obesity, 17 2 Sensitivity represented no heterogeneity or pleiotropy in this study. Conclusion Our findings support microbiota, These biomarkers provide new insights into mechanisms underlying contribute its prevention, diagnosis, treatment.

Role of chemokines CXCL9, CXCL10, CXCL11, and CXCR3 in the serum and minor salivary gland tissues of patients with Sjögren’s syndrome

Clinical and Experimental Medicine, Journal Year: 2024, Volume and Issue: 24(1)

Published: June 20, 2024

Abstract This study aimed to investigate the serum and expression levels of C-X-C motif chemokine ligand 9 (CXCL9), CXCL10, CXCL11, CXC receptor 3 (CXCR3) in minor salivary glands (MSGs) patients with primary Sjögren’s syndrome (pSS), explore their correlations clinical parameters. Serum samples from 49 diagnosed pSS, 33 rheumatoid arthritis (RA), 30 healthy controls (HCs) were collected for measurements CXCL9, CXCR3. Additionally, CXCL MSG tissues measured 41 who underwent biopsy. Correlations between CXCL/CXCR serum/MSG factors/salivary scintigraphy parameters analyzed. CXCL11 CXCR3 showed statistically significant differences among pSS RA HCs (serum pSS:RA:HC = 235.6 ± 500.1 pg/mL:90.0 200.3 pg/mL:45.9 53.6 pg/mL; p 0.041, CXCR3, 3.27 1.32 ng/mL:3.29 1.17 ng/mL:2.00 1.12 ng/mL; < 0.001). CXCL10 a difference (64.5 54.2 pg/mL) (18.6 18.1 pg/mL, 0.001), while CXCL9 did not exhibit groups.
