Clinical validation of a novel metagenomic nanopore sequencing method for detecting viral respiratory pathogens: diagnostic accuracy study Background Clinical metagenomics (CMg) offers high-throughput respiratory pathogen detection with a wider range than targeted, probe-dependent diagnostics. Sequencing cost and the challenges of high h...

New preprint from us @modmedmicro.bsky.social where we validate the diagnostic accuracy of a metagenomic nanopore sequencing method for respiratory RNA viruses.

A Novel Prognostic Metric Resolves the MYCN enigma in Silico and Points to a Biosynthetic Regulatory Shift Driven by MYCN Amplification in Neuroblastoma Neuroblastoma (NB) is the most common extra-cranial solid tumour in children. Although MYCN amplification is typically indicative of a poor prognosis, the expression level of MYCN has a non-monotonic ...

🔹 Favourable outcomes in MYCN-amplified tumours require very high biosynthesis and ATM signalling — rarely achievable biologically.

We propose:
🔹 The p53/MYCN ratio is a superior prognostic metric to MYCN alone in neuroblastoma.
🔹 MYCN drives biogenesis, but amplification or co-mutations trigger a shift that lowers p53/MYCN → worse outcomes.

5 years ago, my MSc project with @insigneoinstitute.bsky.social modelled the MYCN–MDM2–ARF–p53 network in neuroblastoma. That work has evolved into a full study!

The preprint by Matteo et al. explores the MYCN enigma — why MYCN amplification predicts poor prognosis, but overexpression alone doesn’t
