Sexual Dimorphism in the Age of Genomics: How, When, Where

Frontiers in Cell and Developmental Biology, 2019
In mammals, sex chromosomes start to program autosomal gene expression and epigenetic patterns very soon after fertilization. Yet whether the resulting sex differences are perpetuated throughout development and how they connect to the sex-specific ...

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

Advanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

Have necrohormones a role in embryogenesis?

Acta Societatis Botanicorum Poloniae, 2014
The recognition of apoptosis (programmed cell death) as an accompaniment of normal development, the products released by the protoplasts undergoing self-destruction being utilized by adjacent living cells, stimulates renewed interest in Haberlandt's ...

Growth Charts for Children With Beckwith–Wiedemann Spectrum

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Beckwith–Wiedemann spectrum (BWSp) is an overgrowth disorder caused by (epi)genetic alterations in chromosome 11p15. This study aimed to develop BWSp‐specific growth charts and explore genotype/phenotype correlations with respect to growth. Heights, weights, and head circumferences were retrospectively collected from 581 individuals with BWSp ...

Desynchronizing Embryonic Cell Division Waves Reveals the Robustness of Xenopus laevis Development

Cell Reports, 2017
The early Xenopus laevis embryo is replete with dynamic spatial waves. One such wave, the cell division wave, emerges from the collective cell division timing of first tens and later hundreds of cells throughout the embryo.

Cohesins: Crossroad Between Cornelia de Lange Spectrum and Cancer Predisposition

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The cohesin complex plays crucial roles in DNA repair, chromatid separation, and gene transcription regulation. Pathogenic variants in cohesins or dysfunctional transcriptional regulators lead to cohesinopathies, a broader group of disorders including Cornelia de Lange Spectrum (CdLSp), for which the prevalence of cancer cases remains unclear.

Two New Cases Expand the Phenotypic Spectrum of TUBG1 Missense Variants

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The gamma‐tubulin ring complex (γ‐TuRC) plays a role in coordinating centrosome and spindle pole body formation during cell division. TUBG1 encodes a critical component of the γ‐TuRC. Pathogenic TUBG1 variants can cause a range of alterations in cortical gyral patterning, microcephaly, and other neurological manifestations.

Embryology of Ageratum conyzoides L. and A. fastigiatum R.M. King & H. Rob. (Asteraceae)

Acta Botânica Brasílica, 2015
Ageratum has a complex circumscription, and recent studies have indicated its polyphyletism. The genus has been placed in the tribe Eupatorieae whose embryology is not fully known.
