Pediatric dilated cardiomyopathy (DCM) is the most common indication for heart transplantation in children. Despite similar genetic etiologies, medications routinely used in adult heart failure patients do not improve outcomes in the pediatric population. The mechanistic basis for these observations is unknown. We hypothesized that pediatric and adult DCM comprise distinct pathological entities, in that children do not undergo adverse remodeling, the target of adult heart failure therapies. To test this hypothesis, we examined LV specimens obtained from pediatric and adult donor controls and DCM patients. Consistent with the established pathophysiology of adult heart failure, adults with DCM displayed marked …

Genomic Landscape And Evolution Of Metastatic Chromophobe Renal Cell Carcinoma, Jozefina Casuscelli, James J. Hsieh, Et Al Jun 2017

Genomic Landscape And Evolution Of Metastatic Chromophobe Renal Cell Carcinoma, Jozefina Casuscelli, James J. Hsieh, Et Al

Open Access Publications

Chromophobe renal cell carcinoma (chRCC) typically shows ~7 chromosome losses (1, 2, 6, 10, 13, 17, and 21) and ~31 exonic somatic mutations, yet carries ~5%-10% metastatic incidence. Since extensive chromosomal losses can generate proteotoxic stress and compromise cellular proliferation, it is intriguing how chRCC, a tumor with extensive chromosome losses and a low number of somatic mutations, can develop lethal metastases. Genomic features distinguishing metastatic from nonmetastatic chRCC are unknown. An integrated approach, including whole-genome sequencing (WGS), targeted ultradeep cancer gene sequencing, and chromosome analyses (FACETS, OncoScan, and FISH), was performed on 79 chRCC patients including 38 metastatic (M-chRCC) …

Open Access Publications

Clinically useful molecular tools to triage gastric cancer patients are not currently available. We aimed to develop a molecular tool to predict gastric cancer risk in endoscopy-driven biopsies obtained from high-risk gastric cancer clinics in low resource settings.We discovered and validated a DNA methylation biomarker panel in endoscopic samples obtained from 362 patients seen between 2004 and 2009 in three high-risk gastric cancer clinics in Lima, Perú, and validated it in 306 samples from the Cancer Genome Atlas project ("TCGA"). Global, epigenome wide and gene-specific DNA methylation analyses were used in a Phase I Biomarker Development Trial to identify a …


Gastrointestinal Stromal Tumors (Gists): Point Mutations Matter In Management, A Review, Peter J. Oppelt, Angela C. Hirbe, Brian A. Van Tine Jun 2017

Gastrointestinal Stromal Tumors (Gists): Point Mutations Matter In Management, A Review, Peter J. Oppelt, Angela C. Hirbe, Brian A. Van Tine

Open Access Publications

The therapeutic implications of the genomic alterations seen within the drivers of gastrointestinal stromal tumors (GIST) are among the best understood in all of solid tumors. Sequencing of cKIT and PDGFRα should be considered standard practice for the treatment of GIST patients. In this article, we will review the common mutations and how they are utilized in clinical management. In addition, we will review the rare D842V PDGFRα mutation and the diverse molecular group that lacks a mutation in either cKIT or PDGFRα (wild-type GIST) which are best treated on clinical trial. Finally, we will look forward at the future …

Promising Therapeutics Of Gastrointestinal Cancers In Clinical Trials, Lingling Du, Zheng Che, Andrea Wang-Gillam

Open Access Publications

Many novel therapeutics are being developed for patients with cancers along the gastrointestinal (GI) tract. These emerging agents are frequently classified by their biological targets such as tumor growth pathways, tumor metabolism, microenvironment, etc. Some agents targeting cancer growth pathways are based on existing clinically validated therapeutic targets, such as regorafenib for hepatocellular carcinoma (HCC), while other agents focus on newly identified targets, such as


Molecular Landscape And Sub-Classification Of Gastrointestinal Cancers: A Review Of Literature, Bita Fakhri, Kian-Huat Lim Jun 2017

Molecular Landscape And Sub-Classification Of Gastrointestinal Cancers: A Review Of Literature, Bita Fakhri, Kian-Huat Lim

Open Access Publications

The historical approach of diagnosing cancer types based entirely on anatomic origin and histologic features, and the "one-size-fit-all" therapeutic approach, are inadequate in modern cancer treatment. From decades of research we now know that cancer is a highly heterogeneous disease driven by complex genetic or epigenetic alterations. The advent of various high throughput molecular tools has now enabled us to view and sub-classify each cancer type based on their distinct molecular features, in addition to histologic classification, with the promise of individualized treatment strategies tailored towards each specific subtype to improve patient outcomes. In this review, we have made an …

Current Biologics For Treatment Of Biliary Tract Cancers, Diana Y. Zhao, Kian-Huat Lim

Open Access Publications

Biliary tract cancers (BTC) is a group of malignancies that arise from the epithelial cells of the biliary tree. These cancers are typically classified by anatomic site of origin: intrahepatic cholangiocarcinoma (IHCC) and extrahepatic cholangiocarcinoma (EHCC), and gallbladder cancer (GBC). To date, complete surgical resection remains the mainstay of treatment especially for earlier stage disease. Unfortunately, most patients present with advanced or metastatic disease, when systemic chemotherapy is the only treatment option. Due to the paucity of effective treatments, BTCs have a dismal prognosis. There is a tremendous need to better understand the disease biology, discover new therapies, and improve …


Biologic Therapy In Esophageal And Gastric Malignancies: Current Therapies And Future Directions, Pamela Samson, A. Craig Lockhart Jun 2017

Biologic Therapy In Esophageal And Gastric Malignancies: Current Therapies And Future Directions, Pamela Samson, A. Craig Lockhart

Open Access Publications

Biologic agents, including targeted antibodies as well as immunomodulators, are demonstrating unparalleled development and study across the entire spectrum of human malignancy. This review summarizes the current state of biologic therapies for esophageal, esophagogastric, and gastric malignancies, including those that target human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), c-Met, mechanistic target of rapamycin (mTOR) and immunomodulators. We focus primarily on agents that have been included in phase II and III clinical trials in locally advanced, progressive, or metastatic esophageal and gastric malignancies. At this time, only two biologic therapies are …

Glaucoma is the second leading cause of blindness worldwide. Physicians often use surrogate endpoints to monitor the progression of glaucomatous neurodegeneration. These approaches are limited in their ability to quantify disease severity and progression due to inherent subjectivity, unreliability, and limitations of normative databases. Therefore, there is a critical need to identify specific molecular markers that predict or measure glaucomatous neurodegeneration. Here, we demonstrate that growth differentiation factor 15 (GDF15) is associated with retinal ganglion cell death. Gdf15 expression in the retina is specifically increased after acute injury to retinal ganglion cell axons and in a murine chronic glaucoma model. …
