Background: Fructus Viticis Total Flavonoids (FVTF) is a novel candidate preparation that possesses anticancer activity. However, the role and mechanism of FVTF-inhibiting human hepatocellular carcinoma (HCC) cell stem properties is unclear.
Methods: Liquid chromatography (LC) in conjugation with mass spectrometer (MS) was used to identify the compounds of FVTF.
PD-L1 is an immune checkpoint molecule mediating cancer immune escape, and its expression level in the tumor has been used as a biomarker to predict response to immune checkpoint inhibitor (ICI) therapy. Our previous study reveals that an 11 amino acid-long ANXA1-derived peptide (named A11) binds and degrades the PD-L1 protein in multiple cancers and is a potential peptide for cancer diagnosis and treatment. Near-infrared fluorescence (NIF) optical imaging of tumors offers a noninvasive method for detecting cancer and monitoring therapeutic responses.

The protein kinase casein kinase 2 (CK2) has been implicated in stem cell maintenance and its aberrant activation has been demonstrated in several types of cancer, including cervical cancer. In the present study, it was demonstrated that the sphere-forming cells (SFCs) of HeLa cell lines exhibited self-renewal capacity, indicating that they possessed the properties of cervical cancer stem-like cells. HeLa-derived SFCs exhibited a higher level of CK2α protein, compared with the parental cells.

In the present study, the anti-carcinogenic effects of casticin on human colon cancer and the underlying mechanisms were investigated.

This study aimed to investigate the role of forkhead box O3 (FOXO3a) in breast cancer cells and examine the regulatory mechanisms of FOXO3a in response to casticin treatment of the cells by ELISA, flow cytometry, small interfering RNA (siRNA) transfection and western blot analysis. Casticin treatment induced apoptosis and reduced the expression of the transcription factor forkhead box protein M1 (FOXM1).

The aim of this study was to investigate the effects of casticin on epithelial-mesenchymal transition (EMT) of liver cancer stem cells (LCSCs) derived from the SMMC-7721 cell line. Our results demonstrated that CD133 sphere-forming cells (SFCs) sorted from the SMMC-7721 cell line not only possessed a higher capacity to form tumor spheroids , but also had a greater potential to form tumors when implanted in Balb/c-nu mice, indicating that CD133 SFCs possessed similar traits to LCSCs.

The aim of the present study was to examine the molecular mechanisms by which casticin induces apoptosis in ovarian cancer cells. The human ovarian cancer cell lines SKOV3 and A2780 were cultured .

In this study, we demonstrated that NOC significantly induces apoptosis of MDA-MB-453 cells and that this is primarily mediated through a mitochondrial death cascade. This was presented as a loss of mitochondrial membrane potential, release of cytochrome c and activation of caspase-9.
