السلحفاة «جوناثان» تكشف أحد أسرار العمر المديد

ملخص الخبر

كشف فريق دولي عن سر من أسرار العمر المديد عبر دراسة سلحفاة عملاقة تبلغ من العمر 194 عاماً.
أظهرت الدراسة أن المحفزات الجينية المسؤولة عن إنتاج الطاقة لدى السلحفاة حافظت على نظامها وكأنها كائن شاب.
ساهمت هذه النتائج في فهم كيفية حماية الميتوكوندريا من التدهور المرتبط بالشيخوخة مما قد يساهم في إطالة العمر الصحي للإنسان.
استخدم الباحثون تقنيات تسلسل الجينوم لتحديد مستويات الإنتروبيا في نمط المثيلة التي تنظم عمل الجينات.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

اكتشف باحثون أن محفزات الجينات المسؤولة عن إنتاج الطاقة في الميتوكوندريا لدى «جوناثان» حافظت على انتظام يشبه ذلك الموجود في الكائنات الشابة رغم بلوغه 194 عاماً.
