SUMMARY

Mark A. McNiven, Ph.D., conducts research focused on the liver and the pancreas, as the cells of these organs are susceptible to becoming particularly deadly cancers.

His research investigates how cytoskeletal and membrane dynamics support basic cellular functions during healthy and disease states. Dr. McNiven strives to understand how liver and pancreas cells synthesize, transport, signal and degrade growth factor receptors that are essential to tumor growth and migration.

Cancerous tumors in the liver or pancreas can aggressively spread (metastasize) out of the organ of origin to invade peripheral tissues. Understanding and attempting to attenuate metastasis is a central directive of Dr. McNiven's research.

Additionally, the liver is a central storage site for fat, and can become excessively fatty (steatotic), leading to hepatitis or cancer. Dr. McNiven studies how liver cells store and utilize excess fat and how damage caused by factors such as alcohol can lead to fatty liver disease.

Focus areas

  • Metastatic invasion of tumors into peripheral tissues
  • Cell functions, including cell migration, invasion and metastasis
  • Cellular membrane and cytoskeletal interactions as they relate to cancer metastasis
  • Storage and utilization of fats and lipids in the liver
  • Cellular resistance to viral infection
  • Pathways in liver function, physiology and disease
  • Vesicle formation during endocytosis and secretion

Significance to patient care

A better understanding of cellular mechanisms and metabolic functions will lead to better treatment outcomes for fatty liver disease, hepatitis B, and pancreatic and hepatic cancers by inhibiting tumor growth and metastasis, pathogenic infection, receptor signaling, and growth cascades.
