Prospects of Immunotherapy for Triple-Negative Breast Cancer.

In the classification and typing of breast cancer, triple-negative breast cancer (TNBC) is one type of refractory breast cancer, while chemotherapy stays in the traditional treatment methods. However, the impact of chemotherapy is short-lived and may lead to recurrence due to incomplete killing of tumor cells. The occurrence, development, and relapse of breast cancer are relevant to T cell dysfunction, multiplied expression of related immune checkpoint molecules (ICIs) such as programmed death receptor 1 (PD-1), programmed cell death 1 ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) produce immunosuppressive effect.

The Chinese Herbal Formula Ruyan Neixiao Cream Inhibits Angiogenesis of Precancerous Breast Lesions via Regulation of Ras/Raf/MEK/ERK Signaling Pathway.

Ruyan Neixiao Cream (RUc) is a traditional Chinese herbal formula which can effectively inhibit the angiogenesis of breast precancerous lesions. In order to reveal the specific mechanism, we carried out experiments in vitro and in vivo. We found that the conditioned medium of MCF-10AT cells treated with RUc transdermal solution (RUt) could significantly inhibit the proliferation, migration, invasion, tube formation of HUVECs and the capillary formation of rat aortic rings.

To explore immune synergistic function of Quercetin in inhibiting breast cancer cells.

Background: The precancerous disease of breast cancer is an inevitable stage in the tumorigenesis and development of breast neoplasms. Quercetin (Que) has shown great potential in breast cancer treatment by inhibiting cell proliferation and regulating T cell function. γδ T cells are a class of nontraditional T cells that have long attracted attention due to their potential in immunotherapy.
