Positive feedback and tumorigenesis

Research reveals that cancer cells use a positive feedback loop involving c-MYC and SIRT1 to drive continuous cell division and tumor growth. This mechanism undermines normal cell regulation, leading to uncontrolled proliferation and treatment resistance in certain types of cancer.

Study reveals how normal cells fuel tumor growth

Researchers at Ohio State University found that normal cells in tumors can enhance cancer cell growth after losing a tumor suppressor gene called Pten. The study suggests interrupting signals between normal cells and cancer cells as a new approach to treating breast cancer.

Breast cancer and heart disease may have common roots

Research reveals that women at risk for breast cancer are also at a higher risk for heart disease due to mutations in the BRCA1 and BRCA2 genes. The study found that these genes regulate heart function and can lead to increased mortality rates after a heart attack.
