Dysregulated cell–cell adhesion plays a critical role in epithelial cancer development . Studies of human and mouse cancers have indicated that loss of adhesion complexes known as adherens junctions contributes to tumor progression and metastasis . In contrast , little is known regarding the role of the related cell–ce... | Changes in tissue architecture , such as loss of adhesion between cells , have been shown to facilitate cancer development , especially metastasis where cells can detach from a tumor and spread throughout the body .

The rearrangement of pre-existing genes has long been thought of as the major mode of new gene generation . Recently , de novo gene birth from non-genic DNA was found to be an alternative mechanism to generate novel protein-coding genes . However , its functional role in human disease remains largely unknown . Here we ... | The MYCN oncogene has a central role in the genesis and progression of neuroblastomas , and its amplification is associated with an unfavorable prognosis .

Most mammalian genes often feature alternative polyadenylation ( APA ) sites and hence diverse 3’UTR lengths . Proliferating cells were reported to favor APA sites that result in shorter 3’UTRs . One consequence of such shortening is escape of mRNAs from targeting by microRNAs ( miRNAs ) whose binding sites are elimina... | MicroRNAs ( miRNAs ) are regulators of gene expression . Typically they recognize a binding site in genes' sequences and exert a repressive effect . This scheme prescribes a regulatory network that determines which gene is regulated by which miRNA .

The first step in organization of the body plan of the mouse embryo , specification of the anterior-posterior body axis , depends on migration of the anterior visceral endoderm from the distal tip of the embry... | The specification of the anterior-posterior body axis of the mouse embryo depends on migration of the anterior visceral endoderm ( AVE ) to a position that overlies the future head . By high-resolution imaging of intact embryos we show that movement of the AVE is a form of collective cell migration , as the migrating c... | [

Transcriptional and post-transcriptional regulation shape tissue-type-specific proteomes , but their relative contributions remain contested . Estimates of the factors determining protein levels in human tissues do not distinguish between ( i ) the factors determining the variability between the abundances of different... | The identity of human tissues depends on their protein levels . Are tissue protein levels set largely by corresponding mRNA levels or by other ( post-transcriptional ) regulatory mechanisms ? We revisit this question based on statistical analysis of mRNA and protein levels measured across human tissues . We find that f... | [
