Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

The Discovery of XY Sex Chromosomes in a \u3cem\u3eBoa\u3c/em\u3e and \u3cem\u3ePython\u3c/em\u3e [PDF]

, 2017
For over 50 years, biologists have accepted that all extant snakes share the same ZW sex chromosomes derived from a common ancestor [1, 2, 3], with different species exhibiting sex chromosomes at varying stages of differentiation.

Variation in adult sex ratios in tetrapods is linked to sex chromosomes through mortality differences between males and females.

PLoS Biology
Sex chromosomes can determine male and female phenotypes, and the resulting sex differences may have significant impacts on ecology and life history. One manifestation of this link is that ZW/ZZ sex-determination systems are associated with more male ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Key events in the process of sex determination and differentiation in early chicken embryos

Animal Bioscience
Objective: Current understanding of sex determination and differentiation mechanisms during early chicken embryonic development remains incomplete. To address this, we applied RNA sequencing to identify male-female expression differences at critical developmental stages (E0 blastocysts, E3.5-E6.5 genital ridges, E18.5 gonads), focusing on glycolysis ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Ovarian activity regulation by anti-Müllerian hormone in early stages of human female life, an overview

Anthropological Review, 2018
The present study aimed at describing the anti-Müllerian hormone (AMH), with special focus on molecular background for ovarian activity, in particular the role AMH plays in sex determination and gonadogenesis process in early stages of prenatal life and ...

Loss of mitogen-activated protein kinase kinase kinase 4 (MAP3K4) reveals a requirement for MAPK signalling in mouse sex determination.

PLoS Biology, 2009
Sex determination in mammals is controlled by the presence or absence of the Y-linked gene SRY. In the developing male (XY) gonad, sex-determining region of the Y (SRY) protein acts to up-regulate expression of the related gene, SOX9, a transcriptional ...

Size of coronoid process and ramus as novel parameters in determination of mandibular sex

Indian Journal of Clinical Anatomy and Physiology, 2020
Introduction: The mandibular coronoid process is derived from a Greek word ‘korone’ and described as a triangular piece of flattened bone which projects upwards from the anterior part of the mandibular ramus. However it exists in various shapes and sizes.
