Abstract
This review delves into the groundbreaking impact of induced pluripotent stem cells (iPSCs) and three-dimensional organoid models in propelling forward neuropathology research. With a focus on neurodegenerative diseases, neuromotor disorders, and related conditions, iPSCs provide a platform for personalized disease modeling, holding significant potential for regenerative therapy and drug discovery. The adaptability of iPSCs, along with associated methodologies, enables the generation of various types of neural cell differentiations and their integration into three-dimensional organoid models, effectively replicating complex tissue structures in vitro. Key advancements in organoid and iPSC generation protocols, alongside the careful selection of donor cell types, are emphasized as critical steps in harnessing these technologies to mitigate tumorigenic risks and other hurdles. Encouragingly, iPSCs show promising outcomes in regenerative therapies, as evidenced by their successful application in animal models.

FISH PHYSIOLOGY AND BIOCHEMISTRY 2017; 43:1443-1461.

Abstract
cMyc is a vital transcription factor that involves in the regulation of cell proliferation, growth, differentiation, and apoptosis. In the present study, cMyc in Larimichthys crocea (Lc-cMyc) was cloned and analyzed for investigating its function. The full-length cDNA of Lc-cMyc was 2089 bp encoding a 440-amino-acid protein (Lc-cMyc). Lc-cMyc had the characteristic helix-loop-helix-leucine-zipper (HLH-LZ) DNA-binding domain and highly conservative in evolution. The expression of Lc-cMyc was detected by quantitative real-time PCR (qRT-PCR) and in situ hybridization, respectively. In tissues, the gender differences of Lc-cMyc expression existed only in gonad and Lc-cMyc was extremely significantly expressed in ovary with the highest level in 635-dph ovary, especially in stages II (late) and III (early) oocytes. A certain degree of expression was examined in head kidney of both sexes and testis with high expression in spermatocyte. In embryos, Lc-cMyc was expressed at all embryonic stages. In early embryogenesis (from two-cell stage to mutiple-cell stage), Lc-cMyc was expressed very highly with a peak at two-cell stage. In late embryogenesis (from blastula stage to 1-day-post-hatching stage), the high expression of Lc-cMyc was detected as the following order: 1-day-post-hatching stage > pre-hatching stage > the appearance-of-optic-vesicles stage = mutiple-cell stage > beginning-of-heart-pulsation stage. The distribution of Lc-cMyc concentrated gradually in the back of embryos until in the head. In conclusion, the spatio-temporal expression patterns of Lc-cMyc indicated an essential role in oogenesis and embryogenesis and contributed to insight into the molecular mechanisms of regulating pluripotency in large yellow croaker.

Çağlayan ES. Generation of improved human cerebral organoids from single copy DYRK1A knockout induced pluripotent stem cells in trisomy 21: hypothetical solutions for neurodevelopmental models and therapeutic alternatives in down syndrome. Cell Biol Int 2016; 40:1256-1270. [PMID: 27743462 DOI: 10.1002/cbin.10694] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2016] [Accepted: 10/12/2016] [Indexed: 01/02/2023]
Abstract
Dual-specificity thyrosine phosphorylation-regulated kinase 1A (DYRK1A) is a strong therapeutic target to ameliorate cognitive functions of Down Syndrome (DS). Genetic normalization of Dyrk1a is sufficient to normalize early cortical developmental phenotypes in DS mouse models. Gyrencephalic human neocortical development is more complex than that in lissencephalic mice; hence, cerebral organoids (COs) can be used to model early neurodevelopmental defects of DS. Single copy DYRK1A knockout COs (scDYRK1AKO-COs) can be generated from manipulated DS derived (DS-) induced pluripotent stem cells (iPSCs) and genetic normalization of DYRK1A is expected to result in corrected neurodevelopmental phenotypes that can be reminiscent of normal COs. DYRK1A knock-in (DYRK1AKI) COs can be derived after genetic manipulations of normal iPSCs and would be valuable to evaluate impaired neocortical development as can be seen in DS-COs. DYRK1A mutations cause severe human primary microcephaly; hence, dose optimization studies of DYRK1A inhibitors will be critical for prenatal therapeutic applications in DS. Several doses of DYRK1A inhibitors can be tested in the neurodevelopment process of DS-COs and DS-scDYRK1AKO-COs would be used as optimum models for evaluating phenotypic ameliorations. Overdose drug exposure in DS-COs can be explained by similar defects present in DS-baDYRK1AKO-COs and DYRK1AKO-COs. There are several limitations in the current CO technology, which can be reduced by the generation of vascularized brain-like organoids giving opportunities to mimic late-stage corticogenesis and complete hippocampal development. In the future, improved DS-DYRK1AKO-COs can be efficient in studies that aim to generate efficiently transplantable and implantable neurons for tissue regeneration alternatives in DS individuals.
