Transcription-factor-dependent noncoding RNA transcription illuminates components of a transcription-factor-dependent gene regulatory network that includes enhancer-associated long noncoding RNAs and is necessary for cardiac rhythm.

Interaction with PUMILIO is essential for maintenance of genomic stability by the cytoplasmic long noncoding RNA NORAD, whereas binding to RBMX is dispensable for this function.
A c-Myc-transcribed long noncoding RNA namely LAST (LncRNA-assisted stabilization of transcripts) collaborates with a cellular factor CNBP to promote the stability of CCND1/cyclin D1 mRNA post-transcriptionally, ensuring the proper G1/Sphase transition of the cell cycle.
The lncRNA pCharme controls the expression of cardiomyocyte maturation genes and heart development by orchestrating the formation of MATR3-enriched nuclear condensates.

Ribosome profiling and loss-of-function during human ESC pancreatic differentiation reveal abundant lncRNA translation and an essential role for translated LINC00261 in beta cell differentiation, likely through a trans-regulatory, microprotein-independent mechanism.
PITAR interaction with TRIM28 mRNA, which encodes a p53 targeting E3 ubiquitin ligase, keeps p53 levels low for cancer cells to divide and attenuates the DNA damage response by p53.
