Project description:The study aims to elucidate the effect of histone methyltransferase SMYD3 on gene expression in MCF-7 breast cancer cell line. Knockdown luciferase control v.s. knockdown SMYD3 in MCF-7 breast cancer cell line were conducted. Results identify a large proportion of cell cycle-related genes regulated by SMYD3.
Project description:Human breast cancer cell line MDA-MB-231 was transduced with lentivirus vector expressing non-specific control (NS) and CFH knockdown (shCFH1) sequences.
Project description:Triple-negative breast cancer (TNBC) is the most aggressive type with poor prognosis among the breast cancers and has a high population of cancer stem cells (CSCs) which are main target to cure and inhibit TNBC. In this study, we analyzed the CSC-related proteome alteration by NEDD4 knockdown in CSC-abundant MDA-MB-231 cells by LC-MS/MS analysis.
Project description:Analysis of gene expression change due to knockdown of Slug expression in a basal-subtype breast cancer cell line, MCFDCIS. Total RNA isolated from MCFDCIS cells transfected with control or Slug specific siRNA.
Project description:The MCF7 cell line represents a typical epithelial cell line and corresponds to luminal A breast cancer (estrogen-responsive). Overexpression of HAX1 was demonstrated in MCF7 cell line as well as in breast cancer samples, suggesting a role of HAX1 in breast cancer progression. HAX1 is a 32-kDa protein of unknown structure, involved in the regulation of apoptosis, cell migration and calcium homeostasis. It was also shown to bind mRNA. Scarcity of structural elements and the presence of a disordered region, inferred from HAX1 sequence, suggests that HAX1 is intrinsically disordered, and may have many protein-protein interactions. So far about 40 different proteins were characterized as HAX1 protein partners. In the present work, applying immunoaffinity chromatography coupled with mass spectrometry, we identified new candidates for HAX1 binding partners in breast cancer cells. Newly identified proteins may be divided into three, partially overlapping groups: cytoskeleton-associated proteins, GTP-ase associated proteins and RNA-binding proteins. These results imply that HAX1 has more protein partners than hitherto described. Subsequent analysis of these interactions may shed some light into molecular mechanisms of HAX1 functions.
