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 ...

Manipulation of arthropod sex determination by endosymbionts: diversity and molecular mechanisms [PDF]

, 2014
International audienceArthropods exhibit a large variety of sex-determination systems both at the chromosomal andmolecular level. Male heterogamety, female heterogamety, and haplodiploidy occurfrequently, but partially different genes are involved ...

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 ...

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.

Sex Determination, Sex Differentiation and Puberty in Fish [PDF]

, 2018
En piscicultura es de gran utilidad conocer los procesos de determinación sexual y los mecanismos que permiten la diferenciación sexual, así como el momento en el cual se alcanza la madurez y los individuos son capaces de reproducirse.

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.

The Genetic Feasibility of Gonadal Development and Fertility in Polyodon-Acipenserid Interfamilial Hybrids: An Opinion on the Chromosomal Basis

Frontiers in Bioscience-Scholar
Interfamilial hybridization between American paddlefish (Polyodon spathula) and Acipenserid (sturgeon) species produces viable hybrid offspring. However, the potential fertility of these hybrids is a critical issue for understanding sex determination ...

Comparative Transcriptome Analysis Reveals Sex-Biased Gene Expression in Juvenile Chinese Mitten Crab Eriocheir sinensis. [PDF]

PLoS ONE, 2015
Sex-biased genes are considered to account for most of phenotypic differences between males and females. In order to explore the sex-biased gene expression in crab, we performed the whole-body transcriptome analysis in male and female juveniles of the ...

Diet dependent sex ratios in Tigriopus californicus: Evidence for environmental sex determination in a system with polygenic sex determination [PDF]

, 2017
By controlling the inheritance of sex, the sex determination mechanism constrains sex allocation strategies and sex ratio adaptation; however, sex ratio selection also influences the evolution of sex determination mechanisms.

Sex ratios in reptiles according to the type of sex determination [PDF]

, 2022
There are many factors influencing sex ratios in reptile populations and these factors can differ among sex ratios in different developmental stages. The observed ratio is the result of many complex processes.
