Not all tumors age alike: Bidirectional epigenetic age shifts across 20 solid tumors

Aditri Mukherji, Subhayan Chattopadhyay

The paper assesses epigenetic age shifts in 20 solid tumors compared to normal tissue, finding tissue-specific acceleration and deceleration patterns rather than a universal trend.

Inferring cell dynamics in stress-induced neuroblastoma cell cultures

Khrystyna Hafiichuk, Sara Hamis, Jenny Karlsson, David Gisselsson, Subhayan Chattopadhyay

The paper quantifies cell dynamics and interactions in neuroblastoma cell cultures under stress, finding that cell-to-cell interactions drive phenotypic adaptation, which accelerates with lower nutrient levels.

Tracing the evolution of aneuploid cancers from multiregional sequencing

Subhayan Chattopadhyay, Jenny Karlsson, Anders Valind, Natalie Andersson, David Gisselsson

This paper develops a semi-supervised algorithm to deconvolve clonal variants in tumors, accounting for tumor cell fraction and copy number changes across samples.
