MIR503HG inhibited TNBC tumor growth by downregulating miR-224-5p expression to increase HOXA9 levels in the body
(A) Tumors collected from mice. (B) Effect of MIR503HG overexpression on tumor volume in mice. (C) Effect of MIR503HG overexpression on tumor weight in mice. (D) Quantitative real-time PCR detection of MIR503HG, miR-224-5p, and HOXA9 expression levels in mouse tumor tissues after overexpression of MIR503HG. (E) Immunohistochemical detection of HOXA9. (F–G) Western blotting detection apoptosis-related proteins. Data represent the means ± SD. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
