  1. 1. Investigation of the interaction of A-MYB and TCFL5 on pachytene PIWI-interacting RNA genes in two sub-species of mice, mus musculus musculus and mus musculus castaneus

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Most Shova Banu; [2023]
    Keywords : ;

    Abstract : Spermatogenesis is a complex process that involves the production of sperm cells from germ cells in order to transmit genetic information to progeny. The PIWI-interacting RNA (piRNA) is a non-coding small silencing RNA that guides the PIWI protein to silence target transposon transcripts to regulate the production of germ cells. READ MORE

  2. 2. Single-cell transcriptomic and antibody-based proteomic analysis of Sertoli cell-specific markers in human testis

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Katharina Stanzel; [2023]
    Keywords : ;

    Abstract : The testis is a complex organ responsible for sperm production and hormone synthesis. Spermatogenesis, the process of sperm formation, occurs in the seminiferous tubules and involves the coordinated development of germ cells with the support of Sertoli cells. READ MORE

  3. 3. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Author : Christopher Hampton; [2019]
    Keywords : ;

    Abstract : While endocrine disrupting chemicals have become a serious concern in human and environmental toxicology, many of the methods used for investigating developmental toxicity require long exposure periods, and thus can be technically challenging, labour intensive and expensive. For example, the current standard method, the Larval Amphibian Growth and Development Assay (LAGDA) has an exposure period of ³130 days. READ MORE

  4. 4. Gene Expression Analysis of Loto-Type Toll Receptors in the Onychophoran Euperipatoides kanangrensis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Linushiya Ranjani Lionel Sagayaraj; [2017]
    Keywords : Panarthropods; Loto genes; Convergent extension;

    Abstract : The expression and role of Loto genes was previously investigated in arthropods and it was concluded that the morphogenetic functions of Loto genes were conserved in the last common ancestors of arthropods. In this paper, possible orthologs of Loto clade genes are analysed and it was found that they possibly play a conserved role in convergent extension of cells from the blastoderm stage to germ band extension stage.

  5. 5. The use of endogenous retroviruses as markers to describe the genetic relationships among some local Swedish sheep breeds

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Robert Mukiibi; [2014]
    Keywords : Indigenous Swedish breeds; enJSRV; primitive; endogenous; polymorphism; proviruses;

    Abstract : The present modern sheep is believed to have evolved from its wild ancestors 2.5 million years ago. Furthermore archeological evidence suggest that sheep has been domesticated by man since 8500-9000 years BC for their beneficial products to man including; milk, meat, skin and wool. READ MORE
