Design and Characterization of a Cell-Penetrating Peptide Derived from the SOX2 Transcription Factor.

Int J Mol Sci 2021 Aug 28;22(17). Epub 2021 Aug 28.

Curtin Medical School, Curtin Health Innovation Research Institute and Curtin Institute for Computation, Curtin University, GPO Box U1987, Perth, WA 6845, Australia.

SOX2 is an oncogenic transcription factor overexpressed in nearly half of the basal-like triple-negative breast cancers associated with very poor outcomes. Targeting and inhibiting SOX2 is clinically relevant as high SOX2 mRNA levels are positively correlated with decreased overall survival and progression-free survival in patients affected with breast cancer. Given its key role as a master regulator of cell proliferation, SOX2 represents an important scaffold for the engineering of dominant-negative synthetic DNA-binding domains (DBDs) that act by blocking or interfering with the oncogenic activity of the endogenous transcription factor in cancer cells.

LncRNA NEAT1 controls the lineage fates of BMSCs during skeletal aging by impairing mitochondrial function and pluripotency maintenance.

Cell Death Differ 2021 Sep 8. Epub 2021 Sep 8.

Jiangsu Key Laboratory of Oral Diseases, Nanjing Medical University, Nanjing, Jiangsu Province, China.

Aged bone marrow mesenchymal stem cells (BMSCs) exhibit aberrant self-renewal and lineage specification, which contribute to imbalanced bone-fat and progressive bone loss. In addition to known master regulators of lineage commitment, it is crucial to identify pivotal switches governing the specific differentiation fate of aged BMSCs. Here, we profiled differences in epigenetic regulation between adipogenesis and osteogenesis and identified super-enhancer associated lncRNA nuclear-enriched abundant transcript 1 (NEAT1) as a key bone-fat switch in aged BMSCs.

OCT4 cooperates with distinct ATP-dependent chromatin remodelers in naïve and primed pluripotent states in human.

Nat Commun 2021 08 26;12(1):5123. Epub 2021 Aug 26.

Department of Developmental Biology, Washington University School of Medicine, St. Louis, MO, USA.

Understanding the molecular underpinnings of pluripotency is a prerequisite for optimal maintenance and application of embryonic stem cells (ESCs). While the protein-protein interactions of core pluripotency factors have been identified in mouse ESCs, their interactome in human ESCs (hESCs) has not to date been explored. Here we mapped the OCT4 interactomes in naïve and primed hESCs, revealing extensive connections to mammalian ATP-dependent nucleosome remodeling complexes. Read More

Establishment of Mouse Primed Stem Cells by Combination of Activin and LIF Signaling.

Front Cell Dev Biol 2021 5;9:713503. Epub 2021 Aug 5.

State Key Laboratory of Reproductive Regulation and Breeding of Grassland Livestock, Inner Mongolia University, Hohhot, China.

In mice, embryonic stem cells (ESCs) and epiblast stem cells (EpiSCs) are established from pre- and post-implantation embryos and represent the naive and primed state, respectively. Herein we used mouse leukemia inhibitory factor (LIF), which supports ESCs self-renewal and Activin A (Act A), which is the main factor in maintaining EpiSCs in post-implantation epiblast cultures, to derive a primed stem cell line named ALSCs. Like EpiSCs, ALSCs express key pluripotent genes , , and ; one X chromosome was inactivated; and the cells failed to contribute to chimera formation . Read More

Generation of iPSC line from a Parkinson patient with PARK7 mutation and CRISPR-edited Gibco human episomal iPSC line to mimic PARK7 mutation.

Stem Cell Res 2021 Aug 17;55:102506. Epub 2021 Aug 17.

National Institute on Aging, National Institutes of Health, Bethesda, MD 20892, United States. Electronic address:

Mutations in the oncogene PARK7, which codes for DJ-1, have been associated with early-onset autosomal recessive Parkinson's disease (PD); however, the exact role of DJ-1 in PD remains elusive. Fibroblasts from a PD patient with a uniparental disomy, 1 bp deletion in PARK7 were reprogrammed into the induced pluripotent stem cell (iPSC) line: NIHTVBi015-A. For control purposes, CRISPR-Cas9 editing was used to mimic the mutation in the Gibco Human Episomal iPSC line: TMOi001-A is the control line (A18945) and TMOi001-A-3 is the control-edited line (2B10).

Chromatin lncRNA Platr10 controls stem cell pluripotency by coordinating an intrachromosomal regulatory network.

Genome Biol 2021 08 19;22(1):233. Epub 2021 Aug 19.

Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, Guangzhou, Guangdong, 510530, People's Republic of China.

Background: A specific 3-dimensional intrachromosomal architecture of core stem cell factor genes is required to reprogram a somatic cell into pluripotency. As little is known about the epigenetic readers that orchestrate this architectural remodeling, we used a novel chromatin RNA in situ reverse transcription sequencing (CRIST-seq) approach to profile long noncoding RNAs (lncRNAs) in the Oct4 promoter.

Results: We identify Platr10 as an Oct4 - Sox2 binding lncRNA that is activated in somatic cell reprogramming. Read More
