Summary

This summary is machine-generated.

This study identifies four PANoptosis-related genes that predict breast cancer patient survival and immune infiltration. The findings highlight PANoptosis

Area Of Science

  • Oncology
  • Cell Death Research
  • Bioinformatics

Background

  • Breast cancer (BC) is a leading global malignancy in women.
  • PANoptosis, a novel cell death pathway, is gaining attention.
  • The role of PANoptosis in BC and its related genes is not well understood.

Purpose Of The Study

  • To investigate the role of PANoptosis-related genes in breast cancer prognosis.
  • To develop a predictive risk model for breast cancer based on PANoptosis-related genes.
  • To explore the therapeutic potential of targeting PANoptosis in breast cancer.

Main Methods

  • Utilized public breast cancer expression and clinical data.
  • Developed a risk model using univariate Cox, LASSO, and Kaplan-Meier analyses.
  • Constructed and validated a nomogram for survival probability prediction.

Main Results

  • Identified 4 differentially expressed PANoptosis-related genes impacting overall survival.
  • Established a risk model stratifying patients into low/high-risk groups with distinct prognoses and immune infiltration levels.
  • Developed a nomogram for predicting 1-, 3-, and 5-year survival.
  • XIAP identified as a high-risk factor; its inhibition enhanced doxorubicin's antitumor effect via PANoptosis.

Conclusions

  • PANoptosis plays a significant role in breast cancer prognosis.
  • PANoptosis-related genes can serve as predictive biomarkers for breast cancer.
  • Targeting PANoptosis may offer novel therapeutic strategies for breast cancer.

The Intrinsic Apoptotic Pathway 01:31

6.5K

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Abnormal Proliferation 02:23

4.5K

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Cancer-Critical Genes I: Proto-oncogenes 01:33

8.9K

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

mTOR Signaling and Cancer Progression 03:03

3.8K

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Induced Pluripotent Stem Cells 01:06

4.1K

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
