Кроим ДНК на Python — CRISPR gRNA finder, Часть II: Скоринг, off-target и реальный ген
В первой части мы написали базовый поиск gRNA с фильтрацией по GC-составу. Работает, но тупо: все кандидаты в диапазоне 40-60% считаются равнозначными. В реальности это не так. Сегодня добавим систему скоринга — будем ранжировать gRNA по качеству, учитывая позицию нуклеотидов и особенности U6-промотора. Потом подключим NCBI BLAST, чтобы проверять кандидатов на off-target: не порежет ли Cas9 что-нибудь лишнее в геноме. Тестировать будем на гене CCR5 — том самом, который отредактировал китайский учёный Хэ Цзянькуй в скандальном эксперименте 2018 года.

Кроим ДНК на Python: CRISPR gRNA finder, Часть I: Введение и базовый поиск
Несколько лет назад я наткнулся на статью про CRISPR‑Cas9 и домашние биолаборатории — люди буквально у себя дома экспериментировали с редактированием генов. Я бэкенд‑разработчик, биологию последний раз открывал в школе, но желание разобраться никуда не делось. В этой статье разберёмся, как работает CRISPR на минимальном уровне, и напишем CLI‑утилиту на Python для поиска потенциальных guide RNA — «наводчиков» для молекулярных ножниц Cas9.

Bevor ich für @sciencenotes zu Grüner Gentechnik recherchiert habe, hatte ich keine Meinung zu dem Thema. Dann habe ich viele Studien gelesen. Und nun frage ich mich, wovor so viele Menschen Angst haben. Einen Überblick gibt's im #faq.

They call it “#skeletal #editing” and they hope it will change their field – and our world.
Inspired in part by the revolutionary genome-editing technology #Crispr-#Cas9, Levin and Sarpong are among a handful of chemists developing new methods to #insert, #delete and #swap individual atoms within molecules.
The word “editing” evokes chemists altering atoms with pairs of nanoscopic tweezers, but that would be far from efficient. “If you wanted to make a mole,” Levin explains, referring to a unit of measurement used in chemistry, “you would have to take that pair of tweezers and do it 10^23 times.”

J'ai regardé un chouette #documentaire hier soir sur ces fameux "ciseaux génétiques" dont on a entendu parler récemment suite au prix #Nobel de chimie décerné aux chercheuses Emmanuelle #Charpentier et Jennifer #Doudna .
C'était une bonne occasion d'en apprendre un peu plus et de comprendre en quoi ça consistait.
Je l'ai trouvé passionnant et très bien réalisé ce petit documentaire. 🎥⬇️
