Article Title: Mechanistic study of MUC3A in promoting progression of clear cell renal cell carcinoma via the JAK-STAT pathway

doi: 10.3892/or.2026.9119

Figure Lengend Snippet: MUC3A is aberrantly upregulated in ccRCC and associated with poor prognosis. (A) Pan-cancer analysis of MUC3A expression across multiple tumor types based on TCGA data, generated using the GEPIA2 platform. Gene expression values are presented as log2(TPM + 1). (B) Differential expression of MUC3A in tumor and normal samples from the TCGA-KIRC cohort (523 tumor samples vs. 72 normal samples). *P<0.05. (C) Western blotting of MUC3A protein expression in HK-2 and RPTEC/TERT1 non-malignant renal epithelial cell lines and ccRCC cell lines (CAKI-1, OSRC-2, 786-O and ACHN). GAPDH was used as a loading control. (D) Western blotting of MUC3A knockdown efficiency in 786-O and OSRC-2 cells following transient transfection with three independent siRNAs targeting MUC3A. si-2 was selected for subsequent functional experiments due to its superior knockdown efficiency. (E) Kaplan-Meier OS analysis of ccRCC patients stratified into high- and low-MUC3A expression groups using the GEPIA2 platform. (F) Kaplan-Meier DFS analysis of ccRCC patients based on MUC3A expression levels. Data are derived from TCGA unless otherwise indicated.

Article Snippet: Human ccRCC cell lines 786-O (cat. no. CL-0010), OSRC-2 (cat. no. CL-0177), Caki-1 (cat. no. CL-0052) and ACHN (cat. no. CL-0021), as well as non-malignant renal epithelial cells HK-2 (cat. no. CL-0109; all from Procell Life Science & Technology Co., Ltd.) and RPTEC/TERT1 (cat. no. CRL-4031; American Type Culture Collection), were used in the present study.

Figure Lengend Snippet: Treatment of synchronized kidney and muscle cells with recombinant Fbln5 (10ng/mL) disrupts rhythmic gene expression. A,B) Disrupted expression of Clock and Bmal1 but not C) Per2 in mouse myotube C2C12 cells with Fbln5 treatment. D,E) Disrupted expression of Bmal1 and Per1 but not F) Clock in human renal proximal tubule endothelial cells (RPTEC) with Fbln5. n=3 repetitions with biological triplicate. *p<0.05 Vehicle vs Fbln5. Cells were synchronized with dexamethasone prior to treatment with Fbln5 or vehicle.

Article Snippet: The human Renal Proximal Tubule Epithelial Cell (RPTEC) immortalized cell line (ATCC, PCS-400–010) was cultured in complete growth medium consisting of the base medium containing DMEM: F12 Medium (ATCC 30–2006) and the RPTEC Growth Kit components (ATCC ACS-4007) consisting of 5 pM triiodo-L-thyronine, 10 ng/mL recombinant human EGF, 3.5 μg/mL ascorbic acid, 5.0 μg/mL human transferrin, 5.0 μg/mL insulin, 25 ng/mL prostaglandin E 1 , 25 ng/mL hydrocortisone, 8.65 ng/mL sodium selenite and 1.2 mg/mL sodium bicarbonate.
