Project description:The goals of this study are to examine changes in the expression profiles of genes in HuCCT1 cells following CREB3L1 gene silencing. In this study, three groups of Si-Ctrl HuCCT1 cells and three groups of Si-CREB3L1 HuCCT1 cells were used to study the change in expression of the different genes after CREB3L1 gene silencing by RNA-seq.

Project description:The unfolded protein response (UPR) is activated in response to hypoxia-induced stress such as in the tumor microenvironment. This study examined the role of CREB3L1 (cAMP-responsive element-binding protein 3-like protein 1), a member of the UPR, in breast cancer development and metastasis. Initial experiments identified the loss of CREB3L1 expression in metastatic breast cancer cell lines compared to low- or non-metastatic cell lines. When metastatic cells were transfected with CREB3L1 they demonstrated reduced invasion and migration in vitro, as well as a significantly decreased ability to survive under non-adherent or hypoxic conditions. Interestingly, in an in vivo rat mammary tumor model, CREB3L1 expressing cells not only failed to form metastases compared to CREB3L1 null cells but regression of the primary tumors was seen in 70% of the animals as a result of impaired angiogenesis. Microarray and ChIP on Chip analyses identified changes in the expression of many genes involved in cancer development and metastasis, including a decrease in those involved in angiogenesis. These data suggest that CREB3L1 plays an important role in suppressing tumorgenesis and loss of expression is required for the development of a metastatic phenotype. CREB3L1 is a member of the unfolded protein response family of proteins. CREB3L1 expression is lost from metastatic breast cancer cells. We wanted to determine the effctes CREB3L1 expression had on gene expression.

We wanted to determine the effctes CREB3L1 expression had on gene expression. RNA was extracted from LN4D6 rats cells that were either untransfected or transfected with CREB3L1, changes in gene expression following transfection of CREB3l1 were then determined by hybridisation on Affymetrics microarrays.

Project description:Membrane-bound transcription factor CREB3L1 undergoes Regulated Intramembrane Proteolysis (RIP) in response to Hepatitis C infection. RIP activates CREB3L1 so that it can prevent the growth of HCV infected cells through the action of downstream genes. We over-expressed a truncated form of CREB3L1 that does not require RIP to enter the nucleus. Cells over-expressing this truncated form were isolated by Fluorescence Activated Cell Sorting (FACS). We used microarray to determine the downstream genes of CREB3L1 in comparison to a flow sorted empty vector control.
