Overview of Gene Research
BRCA1, short for Breast Cancer 1 protein, is a crucial tumor suppressor gene. It is involved in basic cellular functions like cell replication and DNA synthesis, and is essential for maintaining genome integrity [1,2]. The BRCA1 protein participates in multiple biological pathways, including the DNA damage response, transcriptional control, cell growth, and apoptosis [3].
Mutations in BRCA1 can lead to reduced expression, resulting in impaired mammary gland differentiation and an increased risk of breast and ovarian cancer development [1]. Although it is present in all cells, it remains unclear why its mutations predispose mainly to breast and ovarian cancers [1,2,5]. Intensive research has shown that BRCA1 contributes to DNA repair and transcriptional regulation in response to DNA damage, and is required for the maintenance of chromosomal stability [2].
In conclusion, BRCA1 is vital for normal cellular functions, especially in DNA-related processes. The study of BRCA1, particularly through understanding the effects of its mutations, has significant implications for breast and ovarian cancer research, potentially guiding the development of preventive and therapeutic strategies for these diseases [1,2,4].
