ملخص الخبر

  • يؤدي دخان السجائر إلى إعادة برمجة خلايا الرئة وجعلها أكثر استعدادا للتحول إلى خلايا سرطانية قبل ظهور المرض بسنوات.
  • أظهرت الدراسة أن خطر الإصابة بسرطان الرئة يرتبط بحالة الخلايا عند ظهور الطفرات الجينية وليس بالطفرات وحدها.
  • كشفت التجارب المخبرية عن تغيرات في نشاط الجينات واضطراب مسارات الالتهاب والمناعة وموت الخلايا نتيجة التعرض المزمن لدخان السجائر.
  • تساعد هذه النتائج في تحديد مؤشرات حيوية مبكرة وتطوير أساليب جديدة للوقاية والعلاج من سرطان الرئة.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

كشفت دراسة حديثة أن تأثير التدخين على الرئة قد يتجاوز إتلاف الخلايا، إذ يمكن لدخان السجائر أن يُحدث تغييرات في طريقة عمل الخلايا ويعيد برمجتها، ما يجعلها أكثر استعدادًا للتحول إلى خلايا سرطانية، حتى قبل ظهور المرض بسنوات.
