A novel -mutated human induced pluripotent stem cell model for understanding -mutated tumors

Tumor Biology, 2020
A missense mutation of the guanine nucleotide binding protein alpha stimulating activity polypeptide 1 ( GNAS ) gene, typically Arg201Cys or Arg201His (R201H/R201C), leads to constitutive activation of the Gsα-cyclic AMP (cAMP) signaling pathway that ...

Differentiation of oligodendrocyte progenitor cells from dissociated monolayer and feeder-free cultured pluripotent stem cells. [PDF]

PLoS ONE, 2017
Oligodendrocytes myelinate axons and form myelin sheaths in the central nervous system. The development of therapies for demyelinating diseases, including multiple sclerosis and leukodystrophies, is a challenge because the pathogenic mechanisms of ...

From tumor‐centric to ecosystem‐based hypotheses in brain tumor research and care

Molecular Oncology, EarlyView.
Primary brain tumors, whether in adults or children, present a major challenge because of their dramatic prognosis and the ongoing lack of efficient therapeutic approaches. In recent years, a shift has occurred from tumor‐centric concepts to a more holistic view of these tumors as dynamic ecosystems.

Identification, properties, and clinical significance of putative stem-like cell populations in prostate cancer [PDF]

, 2012
The notion that tumour initiation and heterogeneity might be driven by small population of tumour-initiating cells (TIC) has gained high significance since the pioneering identification of TIC in leukaemia.

Pluripotent Stem Cells as a Model for Human Embryogenesis [PDF]

, 2023
Pluripotent stem cells (PSCs; embryonic stem cells and induced pluripotent stem cells) can recapitulate critical aspects of the early stages of embryonic development; therefore, they became a powerful tool for the in vitro study of molecular mechanisms ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

The TRF1 telomere protein is essential for the generation and maintenance of iPS cells and marks both pluripotent and adult stem cells [PDF]

, 2013
Englisch: Telomeres are nucleoprotein structures that protect the chromosomal ends from being recognized by DNA repair mechanisms as DNA double strand breaks. The Telomeric DNA is bound by various proteins that force the whole structure to fold in the so-

Generation of a human embryonic stem cell line (WAe009-A-3B) carrying homozygous TNNT2 gene knockout by CRISPR/Cas9 editing

Stem Cell Research
The TNNT2 gene encodes cardiac troponin T (cTnT), a critical protein in cardiac muscle contraction. Mutations in TNNT2 are associated with various cardiomyopathies, including hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM), which ...

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
