## Abstract

ABSTRACT
This K08 Mentored Career Development Award proposal describes a 4 year training program for the
candidate, a neurosurgeon-scientist whose long term goal is to become an independent investigator in the
field of primary malignant brain tumors, with a particular focus on the relevance of microRNA-mediated
interference with GBM biology and survival response to conventional therapies. The basic science expertise
earned by the candidate during his graduate studies while a resident in neurosurgery, put him in the ideal
position to carry over this research. Previously, the candidate has shown that miR-128, a microRNA
preferentially expressed in neurons, has an antitumor effect by targeting multiple GBM proteins involved with
stem cell maintenance, as well as resistance to radiation therapy. He now hypothesizes that there are other
microRNAs whose abnormal expression in GBM parallels that of miR-128, and thus that multiple microRNAs
could work in functional clusters to effectively reprogram GBM cells into neuron-like cells by acting on a
multiplicity of proteins with an epigenetic role. He also proposes that this can be harnessed to obtain a major
sensitizing effect to radiation and chemotherapy. To test his hypothesis he proposes the following 3 specific
aims: 1) to investigate the mechanistic and biological relevance of this observed clustering of several
microRNAs in the regulation of multiple epigenetic complexes; 2) to design and construct a viral-based delivery
method to re-express multiple microRNAs in GBM cells thus achieving substantial reprogramming of GBM
cells into a more benign phenotype; 3) to explore how multiple microRNA re-expression can affect key cellular
survival responses implicated in resistance to radiation and temozolomide treatment. This is extremely relevant
because GBM is characterized by multiple aberrancies in several oncogenic pathways, which can not be
targeted by single drugs, but could be regulated by these microRNAs clusters and their unique ability to
simultaneously target multiple proteins fundamental to tumor biology. It is also very innovative, as it proposes a
new approach to investigating the role of microRNAs in GBM, and also outlines a feasible method for
producing artificial DNA sequences encoding multiple microRNAs that can be used in a gene-therapy setting.
The candidate works in an exceptional academic environment, where he has already been able to set up his
research laboratory, and will perform his experiments and proposed research under the guidance of Dr
Chiocca and Dr Godlewsky as his co-mentors. Also, Dr Ligon, an expert in Neural and GBM stem cells and Dr
Haas-Kogan, expert in DNA repair mechanism in brain tumors, will function as advisors for their respective
areas of expertise.
The candidate has already proven himself to be a dedicated and productive researcher, as demonstrated by
his publications, awards, and funding, the last in chronological order being a K12 career development award
