    KK-LC-1 as a Therapeutic Target to Eliminate ALDH+ Stem Cells in Triple Negative Breast Cancer

    Scientists showed that Kita-Kyushu lung cancer antigen-1 (KK-LC-1) determined the stemness of TNBC aldehyde dehydrogenase (ALDH)+ cells via binding with FAT1 and subsequently promoting its ubiquitination and degradation.

    Abstract

    KLF12 Promotes the Proliferation of Breast Cancer Cells by Reducing the Transcription of p21 in a p53-Dependent and p53-Independent Manner

    Investigators examined the role of Kruppel Like Factor 12 (KLF12) in breast cancer and its associated molecular mechanisms. KLF12 was found to promote the proliferation of breast cancer and inhibit apoptosis in response to genotoxic stress.

    Vangl-Dependent Wnt/Planar Cell Polarity Signaling Mediates Collective Breast Carcinoma Motility and Distant Metastasis

    Vangl1 and Vangl2 knockdown and overexpression and Wnt5a stimulation were employed to manipulate Wnt/planar cell polarity signaling in a battery of breast cancer cell lines representing all breast cancer subtypes, and in tumor organoids from MMTV-PyMT mice.

    Hypoxia-Induced Loss of SRSF2-Dependent DNA Methylation Promotes CTCF-Mediated Alternative Splicing of VEGFA in Breast Cancer

    Investigators demonstrated that the splicing factor SRSF2 caused the inclusion of exon-8b, leading to the formation of the anti-angiogenic vascular endothelial growth factor A (VEGFA)-165b isoform under normoxic conditions.
