lithospermum erythrorhizon/breast neoplasms

BACKGROUND Recognition of a new therapeutic agent may activate an alternative programmed cell death for the treatment of breast cancer. OBJECTIVE Here, it has been tried to evaluate the effects of Shikonin, a naphthoquinone derivative of Lithospermum erythrorhizon, on the induction of necroptosis

Steroid sulfatase (STS) has an important role in regulating the biosynthesis of estrogen within breast tumors. We aimed to investigate whether shikonin, an ingredient of Lithospermum erythrorhizon, could modulate STS expression in breast cancer cells. By MTT assay, shikonin inhibited the cell

Shikonin, isolated from the plant Lithospermum erythrorhizon Sieb. Et Zucc, has been reported to induce apoptosis in several tumor cells. However, such effect of shikonin on human breast cancer cells has not been reported. Thus, in the present study, whether shikonin could induce MCF-7 human breast

Triple-negative breast cancer (TNBC) is heterogeneous disease with a poor prognosis. It is therefore important to explore novel therapeutic agents to improve the clinical efficacy for TNBC. The inosine 5'-monophosphate dehydrogenase 2 (IMPDH2) is a rate-limiting enzyme in the de novo synthesis of

Resistance to cell death and reprogramming of metabolism are important in neoplastic cells. Increased resistance to apoptosis and recurrence of tumors are the major roadblocks to effective treatment of triple negative breast cancer. It has been thought that execution of necroptosis involves ROS

Triple-negative breast cancer (TNBC) is characterized by elevated metastasis, low survival, and poor response to therapy. Although many specific and effective agents for treating TNBC have been investigated, promising therapeutic options remain elusive. Here, we screened the inhibitory activities of

Shikonin is a naphthoquinone isolated from the dried root of Lithospermum erythrorhizon, an herb used in Chinese medicine. Although several studies have indicated that shikonin exhibits antitumor activity in breast cancer, the mechanism of action remains unclear. In the present study, we performed

Breast cancer (BC) is the most common cancer in women and, among different BC subtypes, triple negative (TN) and human epidermal growth factor receptor 2 (HER2)-positive BCs have the worst prognosis. In this study, we investigated the anticancer activity of the root ethanolic and hexane extracts
