[HTML][HTML] Transcriptional kinetics and molecular functions of long noncoding RNAs

P Johnsson, C Ziegenhain, L Hartmanis, GJ Hendriks… - Nature Genetics, 2022 - nature.com
An increasing number of long noncoding RNAs (lncRNAs) have experimentally confirmed
functions, yet little is known about their transcriptional dynamics and it is challenging to …

[HTML][HTML] Layer 4 of mouse neocortex differs in cell types and circuit organization between sensory areas

…, S Laturnus, CR Cadwell, L Hartmanis… - Nature …, 2019 - nature.com
Layer 4 (L4) of mammalian neocortex plays a crucial role in cortical information processing,
yet a complete census of its cell types and connectivity remains elusive. Using whole-cell …

Cell type composition and circuit organization of clonally related excitatory neurons in the juvenile mouse neocortex

…, S Papadopoulos, ZH Tan, P Johnsson, L Hartmanis… - Elife, 2020 - elifesciences.org
Clones of excitatory neurons derived from a common progenitor have been proposed to serve

Genomic encoding of transcriptional burst kinetics

…, P Johnsson, M Hagemann-Jensen, L Hartmanis… - Nature, 2019 - nature.com
Mammalian gene expression is inherently stochastic 1 , 2 , and results in discrete bursts of
RNA molecules that are synthesized from each allele 3 , 4 , 5 , 6 – 7 . Although transcription is …

[HTML][HTML] Phenotypic variation of transcriptomic cell types in mouse motor cortex

…, Y Bernaerts, CR Cadwell, JR Castro, L Hartmanis… - Nature, 2021 - nature.com
Cortical neurons exhibit extreme diversity in gene expression as well as in morphological
and electrophysiological properties 1, 2. Most existing neural taxonomies are based on either …
