Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

The effect of microRNA-375 overexpression, an inhibitor of Helicobacter pylori-induced carcinogenesis, on lncRNA SOX2OT [PDF]

, 2016
Background: Helicobacter pylori is a major human pathogenic bacterium in gastric mucosa. Although the association between gastric cancer and H. pylori has been well-established, the molecular mechanisms underlying H.

Single‐Cell Mitochondrial Lineage Tracing Decodes Fate Decision and Spatial Clonal Architecture in Human Hematopoietic Organoids

Advanced Science, EarlyView.
This study repurposes mitochondrial DNA mutations as endogenous barcodes for lineage tracing in human pluripotent stem cell‐derived organoids. Integrated with transcriptomic and spatial data, it reveals NOTCH‐mediated stromal‐progenitor crosstalk orchestrates clonal dynamics and spatial zonation during early hematopoietic development, offering a non ...

A lncRNA fine tunes the dynamics of a cell state transition involving Lin28, let-7 and de novo DNA methylation

eLife, 2017
Execution of pluripotency requires progression from the naïve status represented by mouse embryonic stem cells (ESCs) to a state capacitated for lineage specification. This transition is coordinated at multiple levels.

Snapshots of Pluripotency [PDF]

Stem Cell Reports, 2016
Pluripotency is a unique developmental state that lays the foundation upon which the entire embryo is built. Pluripotent cells possess the unique capacity to generate, in an exquisitely defined sequence, all the distinct cell types comprising the fetal and adult organism. The discovery of pluripotent stem cells and now the ability to generate them from

Gene Expression Profile Changes After Short-activating RNA-mediated Induction of Endogenous Pluripotency Factors in Human Mesenchymal Stem Cells [PDF]

, 2012
It is now recognized that small noncoding RNA sequences have the ability to mediate transcriptional activation of specific target genes in human cells.

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

Advanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Rejuvenation by cell reprogramming: A new horizon in gerontology [PDF]

, 2018
The discovery of animal cloning and subsequent development of cell reprogramming technology were quantum leaps as they led to the achievement of rejuvenation by cell reprogramming and the emerging view that aging is a reversible epigenetic process. Here,
