New pathway found that helps cancer cells make growth-driving proteins

نیا راستہ ملا جو کینسر کے خلیوں کو بڑھوتری والے پروٹین بنانے میں مدد دیتا ہے

नया रास्ता मिला जो कैंसर कोशिकाओं को वृद्धि वाले प्रोटीन बनाने में मदद देता है

New pathway found that helps cancer cells make growth-driving proteins

Key points

اہم نکات

मुख्य बातें

  • Researchers at The University of Texas MD Anderson Cancer Center have found a previously unknown mechanism that helps cancer cells selectively produce proteins that drive tumour growth, including KRAS, one of the most commonly mutated cancer genes.
  • The study, published in Nature Cell Biology, shows the enzyme METTL13 adds a small chemical tag to a protein involved in protein production, helping cancer cells read genetic instructions more efficiently and make larger amounts of growth-promoting proteins, without boosting all proteins.
  • Removing METTL13 lowered KRAS levels and slowed tumour growth in preclinical models, and in lung cancer models resistant to the drug sotorasib it restored sensitivity and extended survival.
  • ٹیکساس یونیورسٹی کے ایم ڈی اینڈرسن کینسر سینٹر کے محققین نے ایک پہلے سے نامعلوم طریقہ کار دریافت کیا ہے جو کینسر کے خلیوں کو منتخب طور پر وہ پروٹین بنانے میں مدد دیتا ہے جو ٹیومر کی بڑھوتری کو آگے بڑھاتے ہیں، جن میں کے آر اے ایس بھی شامل ہے جو سب سے عام تبدیل شدہ کینسر جینز میں سے ایک ہے۔ نیچر سیل بائیولوجی میں شائع مطالعے کے مطابق انزائم ایم ای ٹی ٹی ایل 13 پروٹین بنانے والے ایک پروٹین پر ایک چھوٹا کیمیائی نشان لگاتا ہے، جس سے کینسر کے خلیے جینیاتی ہدایات کو زیادہ مؤثر طریقے سے پڑھ کر بڑھوتری والے پروٹین زیادہ مقدار میں بناتے ہیں، بغیر تمام پروٹینز کو بڑھائے۔ ایم ای ٹی ٹی ایل 13 ہٹانے سے کے آر اے ایس کی سطح کم ہوئی اور ابتدائی ماڈلز میں ٹیومر کی بڑھوتری سست ہوئی، اور سوٹوراسیب دوا کے خلاف مزاحم پھیپھڑوں کے کینسر کے ماڈلز میں اس نے حساسیت بحال کی اور بقا بڑھائی۔ یہ نتائج ابتدائی ہیں اور کلینیکل استعمال سے پہلے مزید تصدیق کی ضرورت ہے۔
  • टेक्सास विश्वविद्यालय के एमडी एंडरसन कैंसर केंद्र के शोधकर्ताओं ने एक पहले से अज्ञात तंत्र खोजा है जो कैंसर कोशिकाओं को चुनिंदा रूप से उन प्रोटीनों को बनाने में मदद देता है जो ट्यूमर की वृद्धि को बढ़ाते हैं, जिनमें KRAS भी शामिल है जो सबसे आम उत्परिवर्तित कैंसर जीनों में से एक है। नेचर सेल बायोलॉजी में प्रकाशित अध्ययन के अनुसार एंज़ाइम METTL13 प्रोटीन बनाने वाले एक प्रोटीन पर एक छोटा रासायनिक निशान लगाता है, जिससे कैंसर कोशिकाएँ आनुवंशिक निर्देशों को अधिक कुशलता से पढ़कर वृद्धि वाले प्रोटीन अधिक मात्रा में बनाती हैं, बिना सभी प्रोटीनों को बढ़ाए। METTL13 हटाने से KRAS का स्तर कम हुआ और प्रारंभिक मॉडलों में ट्यूमर की वृद्धि धीमी हुई, और सोटोरासिब दवा के प्रति प्रतिरोधी फेफड़ों के कैंसर मॉडलों में इसने संवेदनशीलता बहाल की और जीवनकाल बढ़ाया। ये परिणाम प्रारंभिक हैं और नैदानिक उपयोग से पहले और सत्यापन की आवश्यकता है।

The results are preclinical and still need validation before any clinical use.
