🔬 How Small Cell Lung Cancer Hijacks Neuronal Synapses A groundbreaking study led by researchers from the Department of Translational Genomics and SFB1399 has uncovered that SCLC cells form functional synapses with neurons— effectively hijacking neural signaling to promote tumor growth.

Die neue Methode übertrifft bestehende Methoden wie #ChIP-seq und #CUT&RUN in Bezug auf Sensitivität und Auflösung der Ergebnisse. 📈 Die Studie wurde in ‪@natcomms.nature.com‬ veröffentlicht👇 www.nature.com/articles/s41...

🗝️ #DynaTag can reveal nuanced TF occupancy behaviour and shed light on transcriptional regulation in health and disease. In small cell lung cancer #SCLC PDX models, it uncovered surprising gain-of-function p53, FOXA1 & MYC activity post-chemotherapy – not for ASCL1, NEUROD1, POU2F3 or YAP1 (5/7)

How is DynaTag better than CUT&Tag? ⚡Preserves weak/transient TF binding without signal loss ⚡Better signal-to-noise & resolution ⚡Works for all TFs (high and low DNA-binding affinity) & histone marks ⚡Low-input needed, bulk or single-cell, scalable to multi-cellular systems (4/7)

🤔 How to capture nuanced TF-DNA interactions? 💡 Enter #DynaTag: ‘Dynamic targets and Tagmentation’ captures transient TF-DNA interactions that standard CUT&Tag misses. The trick? Sample prep under physiological salt stabilizes specific interactions without promoting untargeted tagmentation 🧂 (3/7)

❗TF occupancy mapping is still challenging. CUT&Tag was a breakthrough, but it has limits… 👉 Doesn’t work well for TFs that only transiently bind DNA 👉 These fleeting interactions are often lost during sample prep That means we’re missing key regulatory events and it’s time for a new method (2/7)

🧵Let’s break down what makes DynaTag so powerful (1/7) #Epigenomics #Genomics

🧪Move over CUT&Tag, there’s a new #TranscriptionFactor mapping method in town. The newly developed DynaTag by Robert and his lab @epistrucstab.bsky.social is faster, cleaner, more sensitive than #ChIPseq, #CUT&RUN and #CUT&Tag. 🔗 Our @natcomms.nature.com‬ paper: www.nature.com/articles/s41...
