Transcriptional Regulation of NUPR1 by MYH11 Activates PI3 K/AKT and Promotes Bladder Cancer Progression Through Ferroptosis and M2 Polarization of Macrophages.

ABSTRACT:

Background

NUPR1 is a small molecule protein that plays an important role in tumor progression and drug resistance. Our previous study found that NUPR1 promotes the progression of bladder cancer, but the specific mechanism is still unclear. MYH11 encodes the smooth muscle myosin heavy chain and belongs to the conventional myosin family. MYH11 has been found to be associated with a variety of malignant tumors.

Methods

We identified MYH11 as an upstream regulator of NUPR1 using a bioinformatics approach and tested this hypothesis by knocking down MYH11 and ChIP-qPCR. Subsequently, we verified the association of MYH11 and NUPR1 with the PI3 K/AKT pathway by WB. In addition, gene enrichment results showed that the effect of NUPR1 on bladder cancer was related to ferroptosis and
