Tumor Discovery Pyroptosis-related genes in breast cancer progression

A present study are significantly associated with mitosis.
Thus, they may point to additional pathways for BC
progression. The down-regulation of RGS1 may be closely
related to DNA methylation-dependent silencing or
immune escape. The RGS1, a member of the G protein
signal transduction family, is an important tumor immune
C escape site. Due to RGS1 being down-regulated in this
28
analysis, a joint study of BC and immune pathways may be
carried out in the future.
The PSME2 might be a significant oncogene or tumor
suppressor gene for the prevention or early diagnosis
of BC. PSME2, which plays the role of an oncogene or
tumor suppressor gene through multiple pathways in
BC, endometrial cancer, and other malignant tumors,
is implicated in immunoproteasome assembly and is
B required for efficient antigen processing. In this study,
PSME2 was down-regulated in BC, indicating that the
diagnosis and recurrence of BC may be related to its
misregulation.
In the risk model, several genes related to BC have not
yet been extensively studied or have unclear pathways,
including PXDNL, ARMH1, and APOBEC3F. First,
up-regulated PXDNL, a member of the peroxidase gene
family, has been identified as a potential independent
prognostic biomarker for BC, and it appears to be
associated with reduced OS and recurrence-free survival
rates. Second, ARMH1, also known as C1orf228, has

been investigated in only three studies, with its relevance
primarily noted in oral squamous cell carcinoma.
Unfortunately, its pathway in BC remains unclear. Finally,
APOBEC3D and APOBEC3F, which are pseudogenes, have
