ملخص الخبر

تعد السلحفاة جوناثان أقدم حيوان بري معروف في العالم ويقدر عمرها بنحو 194 عاماً.
يسعى الباحثون لدراسة جيناتها لفهم عملية الشيخوخة وكيفية الحفاظ على وظائف الجسم لفترات طويلة.
أظهرت النتائج أن منظمات الجينات المسؤولة عن إنتاج الطاقة وإصلاح الحمض النووي لدى السلحفاة ظلت مستقرة.
كشف التحليل عن 287 متغيراً جينياً تعمل على إبطاء الشيخوخة والحد من الالتهابات وكبح انتشار السرطان.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

تتمتع أقدم سلحفاة برية في العالم بحماية بيولوجية ضد آثار الشيخوخة. إذ يقدر عمرها بنحو 194 عاماً وتعد أقدم حيوان بري معروف في العالم فما الذي اكتشفه الباحثون في تركيبتها الجينية؟ وما يعنيه ذلك لأبحاث الشيخوخة؟
