RESEARCH: CANCER
FOLDING PROJECT #17764 PROFILE

This project looks at how proteins use energy from ions to move molecules across cell membranes. These proteins are found everywhere and are important for things like fighting cancer, diabetes, and brain disorders. By studying these proteins, we can learn how they work and maybe find new ways to treat diseases.

Note: This TLDR is a simplication and may not be 100% accurate.

Projects 17745-17750 Molecular basis of secondary active transporters. Secondary active membrane transporters are proteins that utilize ions to transport an assortment of molecules across cell membranes.

These proteins are found in all domains in life and surprisingly, despite vastly different structures, operate under the same mechanism by using an ion gradient to assist in small molecule transport.

Furthermore, many of these secondary active transporters are drug targets to treat diseases like cancer, diabetes, and neurological disorders.

The simulations in this project will allow us to understand a universal role of ion-coupling across different families of proteins.

Secondary active transporters

Proteins that use ions to transport molecules across cell membranes.

Secondary active transporters are essential proteins found in all living organisms. They work by utilizing an existing ion gradient to power the movement of other molecules across cell membranes. This process is crucial for various biological functions, including nutrient uptake, waste removal, and signal transduction. Many secondary active transporters are also drug targets for treating diseases like cancer, diabetes, and neurological disorders.

Membrane transporters

Proteins that move molecules across cell membranes.

Membrane transporters are proteins embedded within the cell membrane that play a vital role in regulating the movement of substances into and out of the cell. They facilitate the transport of nutrients, ions, waste products, and signaling molecules across this selective barrier. Different types of membrane transporters exist, including passive transporters (which move substances down their concentration gradient) and active transporters (which require energy to move substances against their concentration gradient).

Ion gradient

A difference in ion concentration across a membrane.

An ion gradient is a fundamental concept in cellular biology that describes the unequal distribution of charged particles (ions) across a cell membrane. This difference in concentration creates an electrochemical potential that can be harnessed by cells for various purposes, such as powering active transport processes, generating nerve impulses, and maintaining cellular pH balance.

Drug targets

Molecules or biological processes that are potential therapeutic targets.

Drug targets are specific molecules or cellular pathways that pharmaceutical companies aim to modulate (activate, inhibit, or modify) in order to treat diseases. These targets can include proteins, enzymes, receptors, DNA sequences, or even entire signaling networks. Identifying and understanding drug targets is crucial for the development of new and effective medications.

Cancer

A disease characterized by uncontrolled cell growth and spread.

Cancer is a group of diseases characterized by the abnormal growth and spread of cells. These cells divide uncontrollably and can invade surrounding tissues and organs. Cancer arises from mutations in DNA that disrupt normal cellular regulatory mechanisms, leading to unchecked proliferation and evasion of cell death. Various factors contribute to cancer development, including genetic predisposition, environmental exposures, and lifestyle choices.

Diabetes

A metabolic disorder characterized by high blood sugar levels.

Diabetes is a chronic metabolic disorder characterized by elevated levels of glucose (sugar) in the bloodstream. This occurs when the body either does not produce enough insulin (Type 1 diabetes) or cannot effectively use the insulin it produces (Type 2 diabetes). Insulin is a hormone that regulates blood sugar by allowing glucose to enter cells for energy production. Without sufficient insulin, glucose builds up in the bloodstream, leading to various complications such as damage to blood vessels, nerves, and organs.

Neurological disorders

Conditions affecting the nervous system.

Neurological disorders encompass a wide range of conditions that affect the brain, spinal cord, and peripheral nerves. These disorders can manifest as various symptoms, including impaired movement, sensation, cognition, and behavior. Some common neurological disorders include Alzheimer's disease, Parkinson's disease, stroke, epilepsy, multiple sclerosis, and autism spectrum disorder.
