Newly discovered pathway fuels production of cancer-driving proteins

نیا دریافت شدہ راستہ کینسر پیدا کرنے والے پروٹین کی تیاری کو بڑھاتا ہے

नया खोजा गया मार्ग कैंसर पैदा करने वाले प्रोटीन के उत्पादन को बढ़ाता है

Newly discovered pathway fuels production of cancer-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.
  • The study, published in Nature Cell Biology, found that the METTL13 enzyme helps cancer cells make larger amounts of these growth-driving proteins.
  • Removing the enzyme slowed tumour growth in preclinical models and restored sensitivity to targeted treatment, though researchers say more work is needed before it can reach patients.
  • ٹیکساس یونیورسٹی ایم ڈی اینڈرسن کینسر سینٹر کے محققین نے ایک پہلے سے نامعلوم طریقہ کار پایا ہے جو کینسر کے خلیوں کو ٹیومر کی نشوونما بڑھانے والے پروٹین، بشمول KRAS، منتخب طور پر بنانے میں مدد کرتا ہے۔ نیچر سیل بائیولوجی میں شائع ہونے والی تحقیق میں معلوم ہوا کہ METTL13 نامی انزائم کینسر کے خلیوں کو ان نشوونما بڑھانے والے پروٹین کی زیادہ مقدار بنانے میں مدد دیتا ہے۔ اس انزائم کو ہٹانے سے ابتدائی تجرباتی ماڈلز میں ٹیومر کی نشوونما سست ہوئی اور ہدف شدہ علاج کے لیے حساسیت بحال ہوئی، اگرچہ محققین کا کہنا ہے کہ مریضوں تک پہنچنے سے پہلے مزید کام کی ضرورت ہے۔
  • टेक्सास विश्वविद्यालय के एमडी एंडरसन कैंसर सेंटर के शोधकर्ताओं ने एक पहले से अज्ञात तंत्र पाया है जो कैंसर कोशिकाओं को ट्यूमर की वृद्धि बढ़ाने वाले प्रोटीन, जिनमें KRAS भी शामिल है, चुनिंदा रूप से बनाने में मदद करता है। नेचर सेल बायोलॉजी में प्रकाशित अध्ययन में पाया गया कि METTL13 नामक एंज़ाइम कैंसर कोशिकाओं को इन वृद्धि बढ़ाने वाले प्रोटीन की अधिक मात्रा बनाने में मदद करता है। इस एंज़ाइम को हटाने से शुरुआती प्रयोगात्मक मॉडलों में ट्यूमर की वृद्धि धीमी हुई और लक्षित इलाज के प्रति संवेदनशीलता बहाल हुई, हालांकि शोधकर्ताओं का कहना है कि मरीज़ों तक पहुंचने से पहले और काम की ज़रूरत है।
