Research Interests

Dr. Phillip Koeffler studies the cellular
and molecular biology of cancer focusing on glioblastoma multiforme, breast and
lung cancers and leukemias/lymphomas. He has performed a SNP Chip analysis on
more than 2000 cancers of different varieties and used these data to develop
new diagnostic and prognostic indicators of various cancers, as well as to
identify novel alterations in these cancers. He is doing exon sequencing and
paired – end tagged sequencing of selective leukemia and cancer samples at the
time of diagnosis, remission and relapse in order to define the complete
genomic changes at diagnosis and relapse. In addition, he actively studies the
anti-cancer activity of novel compounds including those from various medicinal
plants, nuclear hormone receptor ligands and fusions of monoclonal antibodies
conjugated to various agents. He is also associating in vitro and in vivo
efficacy of a novel compound with the genomic signature of the cancer.

Additional research within Koeffler’s lab

Studies of an adaptor protein LNK that interacts with
activated tyrosine kinase receptors and inhibits the activity of these
activated receptors.

Studies of the dysregulation of circadian rhythm genes in
cancer particularly focusing on PER-1 and PER-2.

Studies of transcription factors particularly their
anti-microbial stimulatory activities in hypoxic conditions.
