Los biólogos han descubierto que la eliminación de los inhibidores de proteínas restaura el equilibrio metabólico.
Biólogos de la Universidad de California, Irvine, descubrieron que la eliminación del componente SAPS3 en ratones les permitió mantener un equilibrio energético normal a pesar de una dieta rica en grasas. Este descubrimiento podría conducir a tratamientos para la obesidad, la diabetes y otros trastornos metabólicos al centrarse en la inhibición de SAPS3.
Comer demasiada grasa aumenta el riesgo de trastornos metabólicos, pero los mecanismos detrás del problema no se conocen bien. Ahora, biólogos de la Universidad de California, Irvine (UCI) han hecho un gran descubrimiento sobre cómo evitar los efectos nocivos de una dieta rica en grasas. Su estudio fue publicado recientemente en la revista científica
“Removing the SAPS3-inhibiting component freed the AMPK in these mice to activate, allowing them to maintain a normal energy balance despite eating a large amount of fat,” said Mei Kong, professor of molecular biology & biochemistry and the study’s corresponding author. “We were surprised by how well they maintained normal weight, avoiding obesity and development of diabetes.”
The discovery could eventually lead to a new way to approach metabolism-related conditions. “If we block this inhibition activity, we could help people reactivate their AMPK,” said first author Ying Yang, a project scientist in the Kong lab. “It could help in overcoming disorders such as obesity, diabetes, fatty liver disease, and others. It’s important to recognize how important normal metabolic function is for every aspect of the body.”
The researchers are working on developing molecules that could inhibit SAPS3 and restore the metabolism’s balance. They plan to next study SAPS3’s role in other conditions with disturbed metabolic systems, such as cancer and aging.
The discovery comes as metabolic-related diseases such as obesity and diabetes continue to rise. More than half of the global population is expected to be overweight or obese by 2035, compared to 38 percent in 2020, according to the World Obesity Federation. The number of people worldwide with diabetes is expected to rise to 578 million by 2030, up 25 percent from 2019, reports the National Center for Biotechnology Information.
