Abstract:
Steroid receptor coactivator (SRC) family members (SRC1, SRC2 and SRC3) are transcriptional co-regulators. SRCs orchestrate gene transcription by inducing transactivation of nuclear receptors and other transcription factors. Overexpression of SRCs is widely implicated in a range of cancers, especially hormone-related cancers. As coactivators, SRCs regulate multiple metabolic pathways involved in tumor growth, invasion, metastasis, and chemo-resistance. Emerging evidence in recent years suggest that SRCs also regulate maturation, differentiation, and cytotoxicity of T cells by controlling metabolic activities. In this review, we summarize the current understanding of the function of SRCs in T cells as well as cancer cells. Importantly, the controversies of targeting SRCs for cancer immunotherapy as well as possible reconciliation strategies are also discussed.
Insights
Steroid receptor coactivators (SRCs) regulate T cell function and cancer cell metabolism. This review explores SRC roles in both, discussing targeting SRCs for cancer immunotherapy.
Area of Science:
- Molecular Biology
- Immunology
- Oncology
Background:
- Steroid receptor coactivators (SRCs) are key transcriptional co-regulators involved in gene expression.
- Overexpression of SRCs is linked to various cancers, particularly hormone-related types.
- SRCs influence tumor progression, metastasis, and chemoresistance through metabolic pathway regulation.
Purpose of the Study:
- To review the function of SRCs in T cells and cancer cells.
- To discuss the controversies and potential strategies for targeting SRCs in cancer immunotherapy.
Main Methods:
- Literature review of studies on SRC function in T cells and cancer.
- Analysis of emerging evidence on SRC-mediated metabolic regulation.
- Discussion of current controversies in SRC-targeted cancer immunotherapy.
Main Results:
- SRCs regulate T cell maturation, differentiation, and cytotoxicity via metabolic control.
- SRCs are implicated in tumor growth, invasion, metastasis, and chemoresistance.
- Evidence suggests SRCs play dual roles in cancer immunity.
Conclusions:
- SRCs are critical regulators in both T cells and cancer cells.
- Targeting SRCs presents complex challenges and opportunities for cancer immunotherapy.
- Further research is needed to reconcile controversies and develop effective SRC-targeting strategies.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
