Figure Lengend Snippet: Knockdown of CCT2 inhibits STAT3 signaling activation in hepatocellular carcinoma cells. The protein levels of STAT3, p-STAT3, MCL1, MMP2 and SOX2 in (A) Huh-7 and (B) HCCLM3 cells were measured by western blotting. The protein levels of (C) p-STAT3, (D) MCL1, (E) MMP2 and (F) SOX2 in subcutaneous tumor tissue were detected by immunohistochemical staining. *P<0.05, **P<0.01 vs. sh-NC. CCT2, chaperonin containing TCP1 subunit 2; sh, short hairpin; NC, negative control; p, phosphorylated; MCL1, myeloid cell leukemia sequence 1; SOX2, SRY-box transcription factor 2.

Figure Lengend Snippet: IL-6 abolishes the effects of CCT2 knockdown on the proliferation and invasion of hepatocellular carcinoma cells. The protein levels of STAT3 and p-STAT3 in (A) Huh-7 and (B) HCCLM3 cells were measured by western blotting. The proliferation of (C) Huh-7 and (D) HCCLM3 cells following CCT2 knockdown and IL-6 treatment was detected using EdU incorporation assay. The invasion of (E) Huh-7 and (F) HCCLM3 cells was assessed using Transwell assay. *P<0.05, **P<0.01 vs. PBS. CCT2, chaperonin containing TCP1 subunit 2; sh, short hairpin; p-, phosphorylated.

Article Snippet: The primary antibodies were as follows: CCT2 (cat. no. 24896-1-AP), β-actin (cat. no. 66009-1-Ig), MMP2 (cat. no. 10373-2-AP), myeloid cell leukemia sequence 1 (MCL1; cat. no. 16225-1-AP) and SRY-box transcription factor 2 (SOX2; cat. no. 11064-1-AP; all Proteintech Group, Inc.) and STAT3 (cat. no. 4904) and phosphorylated (p-)STAT3 (Tyr705; cat. no. 4113; both Cell Signaling Technology, Inc.) The membranes were washed three times in TBST (0.1% Tween-20) for 5 min each at room temperature.

Figure Lengend Snippet: Determination of M1 vs. M2 polarization in iMac. a Pro-inflammatory M1 cytokines IL-1β, TNFα, IL-6, and IL-8 measured by ELISA. b Anti-inflammatory M2 cytokines IL-4, IL-10, IL-13, CCL5, CCL17, and CCL20 measured by ELISA. For a , b iMac were cultured in 6-well plates (3 × 10 6 cells/well). To challenge with tumor factors, iMac were co-cultured with 50% fresh supernatant from SK-MEL-28 cells every 24 h for 3 days. Supernatants were collected during the final 24 h for cytokine measurement. c Activation (phosphorylation) of NF-kB p65, STAT1, STAT3, and STAT6 in iMac was determined using Western blotting after conditioning with melanoma (SK-MEL-28) supernatant for 72 h. Protein band intensity was quantified using Odyssey version 3.0 software. After adjusting for loading using the β-actin band, data are presented as fold change to the iMac (Dox-) group, which is set as 1. For a – c , one-way ANOVA with Bonferroni’s correction for multiple comparisons was used to analyze group comparisons. Data are presented as means ± SD. Each experiment was performed three times, with triplicate samples each time. * p < 0.05, *** p < 0.001, and **** p < 0.0001
