Pulmonary Fibrosis • Pulmonary Fibrosis is a chronic disease that causes inflammation (swelling and irritation) and fibrosis (scarring) of tissue in the lungs. • Approximately 200,000 Americans have it, with an estimated 50,000 new cases each year. • There is no effective treatment for pulmonary fibrosis. Many people live only about 3 to 5 years after diagnosis.
Model Systems • Cell culture • tracheal epithelial cells, bronchial epithelial cells, alveolar epithelial cells (type I and II), pulmonary fibroblasts, microvascular endothelial cells • treatment with TGFß or NECA (5’-N-Ethylcarboxamido adenosine) • Mouse models • bleomycin treated mice • adenosine deaminase (ADA) deficient mice
Methods Currently in Use • Microarrays • mRNA • miRNA • qPCR • SYBR • TaqMan • Mass Spectrometry • Shotgun • iTRAQ

FrontotemporalDementia (FTD) degenerative brain disease that primarily affects the frontal and and temporal lobes of the brain. characterized by an accumulation of abnormal forms of tau proteins in the brain the most common cause of early-onset dementia in people under age 60. affects approximately 250,000 Americans a year, or about 6.7 people per 100,000 among people ages 45 to 64. Due to the symptoms, FTD can be mistaken for Alzheimer's disease, Parkinson's disease or a primarily psychiatric disorder like depression or schizophrenia. There is no treatment or cure yet that can reverse the damage, but medications can help relieve the symptoms.
Research Plan Four transgenic mouse groups for experiments: 1) rTg(tauP301L) : express mutant tau 2) rTg(tauwt) : express wild type tau 3) rTg(PrP)_RML : express prion protein and develop prion disease 4) rTg(PrP)_Clean : express prion protein and stay normal Brains and plasmawill be harvested : monthly up to 9 months for the FTD mouse groups at 10 day intervals for the prion disease mouse groups Multiple Comparisonswill be made to identify shared and unique molecules (miRNAs, Genes, Proteins) and pathways between FTD and prion disease

Huntington Disease • HD occurs in 1 out of 10,000 individuals • Mood swings, cognitive functions, chorea • Symptoms are correlated with spiny neurons • Basal ganglia, caudate nucleus and cortex • “Cause”: mutant Htt gene • (Expanded triplet repeat)
Research at ISB (contemplated) • Computational • Model construction • “Synthetic lethal” networks • Symptom networks • Protein-protein interaction networks • IPS cells • Perturbable • Replicate samples • Model of hard-to-query tissues • (neurons)
Genome Analysis • We are designing a complete genome sequencing project to detect genes that modify and influence the HD phenotype, and that may interact with Htt. • Biomarker • Metabolomics • Serum proteomics, microRNAs • Would like to predict HD onset, progression, use as surrogate endpoints for therapeutic trials • Proteomics • Does Htt (specifically) bind DNA • ChIP seq • We would like to determine proteins that interact with Htt • Mutant and wild type • Cytoplasmic and nuclear locations • Soluble / aggregate • Several cell types
People • Jared Roach • project leader • Nat Goodman • advisory • More to come… A number of researchers have jumped on the “BDNF pathway” bandwagon. A more systematic approach might advance the field.

Glioblastoma Multiforme (GBM) Age <18: 0.41% Ages 18-35: 1.65% Age >70: 21% Ages 35-50: 16% Ages 50-70: 59.9% • The most common primary brain tumor of adults – 52% of all primary brain tumors • Common symptoms: Headaches, memory loss, seizures and behavioral changes • primarily due to increased pressure of the brain caused by rapid growth of the tumor • WHO classification of Brain Tumors • Grade II – Low grade diffuse Astrocytoma • Grade III – Anaplastic Astrocytoma • Grade IV - GBM • Primary GBMs vs Secondary GBMs • Age Distribution
GBM Treatment • Median Survival Time from the time of diagnosis • Without treatment is 3 months • With treatment 12 months • Most patients die within 24 months • Standard care of radiation-plus-temozolomide (TMZ) • 2 month improvement vs radiation alone • Economic Burden to the health care system • $49,242 per patient > 20 x compared to control cancer-free subjects * • * Kutikova et al J. of Neuro-Oncology 2007
