Newly published 精品SM在线影片 research reveals previously unknown qualities of a gene vital to a cell鈥檚 mitochondrial structure and function

A key takeaway from first-year biology is that mitochondria are the powerhouses of cells鈥攊t鈥檚 the thing most people know about them.

However, mitochondria perform a large array of functions for cells beyond generating the chemical energy that powers a cell鈥檚 biochemical reactions. They play a role calcium signaling and storage, signaling between cells and cell death. And through these various and vital mitochondrial functions, a master regulator is the OPA1 gene.

For a long time, researchers have known that OPA1 plays a crucial role in mitochondria. For example, OPA1 helps maintain the architecture of the mitochondria鈥檚 inner membrane. Without that maintenance, a protein, cytochrome c, can leak into the cell and trigger cell death at the wrong time.

While researchers have long known that OPA1 is vital to mitochondria and mitochondrial membranes in human cells, not much has been known about how OPA1 does its work. But research recently published in the journal Nature sheds new lights on how OPA1 helps reshape mitochondrial membranes and how that translates to cellular health.

Halil Aydin, a 精品SM在线影片 assistant professor of biochemistry, led research that discovered surprising plasticity in the vital OPA1 gene.

鈥淲e鈥檝e known for a long time that this gene exists, we know that it鈥檚 important in a variety of diseases, including cardiovascular disease, cancer, neurodegenerative disease,鈥� says principal investigator Halil Aydin, a 精品SM在线影片 assistant professor of biochemistry. 鈥淲hat we didn鈥檛 know is how it functions. Our goal is to understand how it works and then in the future use that as a blueprint for developing therapeutic strategies or drugs.鈥�

Halil Aydin One of Three CU Professors to Win Prestigious Boettcher Investigator Award Anonymous (not verified) Mon, 06/12/2023 - 00:00

The awards are part of $1.88 million in 2023 biomedical research grant funding for Colorado researchers

Halil Aydin is one of three 精品SM在线影片 assistant professors who have been named 2023 Boettcher Investigators, each earning $235,000 in grant funding to support up to three years of biomedical research. The 13-year-old program invests in leading Colorado researchers during the early stages of their careers, providing support to fund their independent scientific research.

The three 精品SM在线影片 award winners and their fields of study are:

Nuris Figueroa, assistant professor, physics; studying the mechanics of mucus organization and transport;
Halil Aydin, assistant professor, biochemistry; investigating cellular and molecular mechanisms of mitochondrial form and function in human health and disease; and
Nick Bottenus, assistant professor, biomedical, mechanics of materials, and robotics and systems design in the College of Engineering and Applied Science; studying binding kinetics of targeted microbubble agents.

Funding for the awards is made possible in part by the Webb-Waring Biomedical Research Awards program, which is administered by the Boettcher Foundation.

鈥淚t鈥檚 an honor to be acknowledged by a distinguished organization,鈥� Aydin said of the Boettcher Foundation. 鈥淭he Boettcher Foundation Webb-Waring Biomedical Research Award will grant our laboratory the opportunity to develop novel approaches and push the boundaries of high-resolution imaging and structural cell biology to advance our understanding of how cellular machines function normally, and how they are corrupted by disease. An integrative understanding of how protein machines function has implications for targeting cardiovascular diseases, metabolic disorders, cancers, aging and a wide range of neurodegenerative diseases.鈥�

Halil Aydin is an expert in membrane biology, cell signaling, proteins and enzymology, molecular biophysics, structural biology, and electron cryo-microscopy (cryoEM).
