SNHG14 and breast carcinoma: According to the expression of SNHG14 in breast cancer cells, among which SKBR‐3 showed the highest level while BT474 indicating a lowest endogenous expression, we constructed SNHG14 overexpression model using BT474 cells and SNHG14 knockdown model using SKBR‐3 cells (Figure 2A,B).
