Control Of The Ras/Erk Signaling Pathway By The Brahma Chromatin-remodeling Complex

Funding Amount
$524,820.00
Summary
Hormones bind and initiate molecular signals within cells to proliferate or change into specific cell types. This is important for growth and development of different tissues. A pathway which is critical for transmitting the effects of hormones in cells is the Ras pathway. New studies by the applicants indicate that the Brahma complex, a molecule important in controlling the levels of proteins in cells, activates the Ras pathway. This project will define how Brahma controls the Ras pathway.
Targeting KRAS Mutations In Cancer Using A Novel SiRNA Delivery Technology

Funding Amount
$498,899.00
Summary
Mutations in a gene called KRAS are found in 20% of human cancers but are impossible to target with existing treatments. RNA interference is a promising new way to target genes previously considered undruggable, but there is no way to deliver the molecules required for RNA interference to tumours. We will evaluate the ability of a new nanotechnology based delivery system (antibody targeted minicells) to deliver RNA interference, thereby selectively targeting of KRAS in tumours while avoiding tox ....Mutations in a gene called KRAS are found in 20% of human cancers but are impossible to target with existing treatments.

We will evaluate the ability of a new nanotechnology based delivery system (antibody targeted minicells) to deliver RNA interference, thereby selectively targeting of KRAS in tumours while avoiding toxicity to normal tissue.Read moreRead less
Studies Of Myeloid Leukaemogenesis In The Zebrafish

Summary
This project aims to investigate the causes of white blood cell cancer, or leukaemia, at the molecular level, using a novel approach in zebrafish. Zebrafish provide a powerful experimental model for developmental genetics, largely due to the visual and technical accessibility of embryos for experimentation. We plan to introduce a fluorescent molecular tag into the white blood cells in order to directly visualise them. We will then predispose these fish to leukaemia and screen for mutants with en ....This project aims to investigate the causes of white blood cell cancer, or leukaemia, at the molecular level, using a novel approach in zebrafish. Zebrafish provide a powerful experimental model for developmental genetics, largely due to the visual and technical accessibility of embryos for experimentation. We plan to introduce a fluorescent molecular tag into the white blood cells in order to directly visualise them. We will then predispose these fish to leukaemia and screen for mutants with enhanced or suppressed leukaemia. We anticipate that the mutants will allow new genes involved in the development of leukaemia to be identified.Read moreRead less
Prorenin And The Prorenin Receptor In Diabetic Retinopathy: Involvement Of The Wnt Pathway And Inflammation

Summary
Diabetic retinopathy is the leading cause of blindness in people of working age. The World Health Organization predicts that by 2030 more than 300 million people will have diabetes. Given the prevalence of diabetic retinopathy and the lack of effective treatments, there is an urgent need to identify the factors that contribute to its development. This project will determine the role of components of a hormonal system, prorenin and its receptor, in diabetic retinopathy and whether they are new ta ....Diabetic retinopathy is the leading cause of blindness in people of working age.
