Article Title: Differential Protumoral Mechanisms Induced by CAFs in Cervical Cancer Cells Occur Independently of 17β-Estradiol Stimulation

doi: 10.3390/cancers18101509

Figure Lengend Snippet: CAFs decrease the mitochondrial metabolism and enhance the ROS production in SiHa cells. Mitochondrial metabolism was assessed by MTT assay, and ROS by H2DCFDA. SiHa and HeLa cells were cultured with LG or HG CAFs’ supernatant prior to metabolism or ROS measurement. ( A ) Mitochondrial metabolism of SiHa and HeLa cells stimulated with LG and HG CAFs, and metabolic activity was normalized against the control. ( B ) Production of ROS by SiHa and HeLa cells stimulated with LG and HG CAFs. Statistical analysis was first performed with a normality test using the Shapiro–Wilk test and later with Kruskal–Wallis or one-way ANOVA. Data is presented as mean ± SD. * p < 0.05, ** p < 0.01, **** p < 0.0001. LG CAF: Cancer-associated fibroblasts from low-grade lesion, HG CAF: Cancer-associated fibroblasts from high-grade lesion, Basal: Cells cultured with DMEM, CAF basal: Cells cultured with CAF’s supernatant without E2 stimulation, CAF E2: Cells cultured with CAF’s supernatant with previous stimulation with E2.

The inhibition rate was subsequently calculated. ( E-I ) Subcutaneous injection of FAM83D-silenced and control HeLa cells into BALB/c Nude mice ( n = 6) was used to determine the tumorigenicity. The tumor growth curves, tumor volumes, and tumor weights were measured. ( J ) And then, the nude mice that developed liver metastases were counted.
