Advanced Science, EarlyView.A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

Effect of 5'UTR introns on gene expression in
BMC Genomics, 2006 Background The majority of introns in gene transcripts are found within the coding sequences (CDSs). A small but significant fraction of introns are also found to reside within the untranslated regions (5'UTRs and 3'UTRs) of expressed sequences ...

Integrated evolution of ribosomal RNAs, introns, and intron nurseries [PDF]
Genetica, 2018 The initial components of ribosomes first appeared more than 3.8 billion years ago during a time when many types of RNAs were evolving. While modern ribosomes are complex molecular machines consisting of rRNAs and proteins, they were assembled during early evolution by the association and joining of small functional RNA units. Introns may have provided

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa
Advanced Science, EarlyView.Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer
Advanced Science, EarlyView.Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

, 2006 If genome space is finite with little, if any, DNA that is not functional under some circumstance, then potential conflicts between different forms of genomic information must be resolved by appropriate trade-offs. These trade-offs sometimes require that genes accommodate spacers, introns, and simple sequence elements.
