Ancestry-dependent gene expression correlates with reprogramming to pluripotency and multiple dynamic biological processes.

Induced pluripotent stem cells (iPSCs) can be derived from differentiated cells, enabling the generation of personalized disease models by differentiating patient-derived iPSCs into disease-relevant cell lines. While genetic variability between different iPSC lines affects differentiation potential, how this variability in somatic cells affects pluripotent potential is less understood. We generated and compared transcriptomic data from 72 dermal fibroblast-iPSC pairs with consistent variation in reprogramming efficiency.

Ras Post-transcriptionally Enhances a Pre-malignantly Primed EMT to Promote Invasion.

Epithelial-to-mesenchymal transition (EMT) is integral to cancer progression, with considerable evidence that EMT has multiple intermediary stages. Understanding the mechanisms of this stepwise activation is of great interest. We recreated a genetically defined model in which primary cells were immortalized, resulting in migratory capacity, and subsequently H-Ras-transformed, causing malignancy and invasion.

RNA regulons in cancer and inflammation.

Gene expression is the fundamental driving force that coordinates normal cellular processes and adapts to dysfunctional conditions such as oncogenic development and progression. While transcription is the basal process of gene expression, RNA transcripts are both the templates that encode proteins as well as perform functions that directly regulate diverse cellular processes. All levels of gene expression require coordination to optimize available resources, but how global gene expression drives cancers or responds to disrupting oncogenic mutations is not understood.

PEEK radiolucent plate for distal radius fractures: multicentre clinical results at 12 months follow up.

Introduction: Open reduction and internal fixation (ORIF) with plate and screws represents the recommended treatment for unstable intra-articular distal radius fractures. Although significant progresses in surgical technique have been made, anatomical reconstruction of radio-carpal articular surface still represent a difficult task, especially in multifragmentary fractures. Available PEEK reinforced-carbon fiber composite radiolucent devices allow both an easier and more careful assessment of intra-operative reduction of the articular surface of distal radius and prompt correction of any residual step deformity.

Fingerprint Change: Not Visible, But Tangible.

Hand-foot syndrome, a chemotherapy-induced cutaneous toxicity, can cause an alteration in fingerprints causing a setback for cancer patients due to the occurrence of false rejections. A colon cancer patient was fingerprinted after not having been able to use fingerprint recognition devices after 6 months of adjuvant chemotherapy. The fingerprint images were digitally processed to improve fingerprint definition without altering the papillary design.
