Blocks to Polyspermy in Fish: A Brief Review
نویسنده
چکیده
Although fertilization was observed by Fol more than 100 years ago, mechanisms for effecting a block to polyspermy in fish are largely unknown. In this review, the recent studies of polyspermy block mechanisms in teleost fish eggs will be presented, including morphological, biochemical, and molecular results.

Mammalian membrane block to polyspermy: new insights into how mammalian eggs prevent fertilisation by multiple sperm.
To inhibit fertilisation by more than one sperm (a condition known as polyspermy), eggs have developed preventative mechanisms known as blocks to polyspermy. The block at the level of the egg extracellular coat (the zona pellucida in mammals, the vitelline envelope in non-mammals) has been well characterised in many different animal species and the block at the level of the egg plasma membrane ...

Chromosomal abnormalities are able to produce genetic instability, which is the main cause of many diseases. Cytogenetics is analysis of any kind of chromosomal abnormalities. Chromosomal alterations can be divided into structural and numerical abnormalities, both of which play a significant role in the development of many diseases, particularly cancer. Today, most cytogenetic analyzes are perf...
متن کاملThe cortical reaction and development of activation competence in mammalian oocytes.
Blocks to polyspermic fertilization are necessary to prevent the incorporation of two sperm nuclei into a zygote's genome, which would result in abnormal development. Many mammalian eggs utilize both an extracellular zona pellucida block to polyspermy and a plasma membrane block. Although little is known about the plasma membrane block in mammals, fertilization results in zona glycoprotein modi...
متن کاملSperm release strategies in marine broadcast spawners: the costs of releasing sperm quickly.
When under competition for fertilisations, males are thought to increase their reproductive success by releasing as many sperm as possible into the reproductive arena and in many species, this prediction holds. For marine invertebrates, which utilise the ancestral strategy of broadcast spawning eggs and sperm, however, it appears that males tend to release their sperm more slowly than females r...
متن کاملFood-Borne Bacteria Associated with Seafoods: A Brief Review
Consumption of contaminated seafoods is a major cause of death and hospitalization particularly in poor and developing countries. As with other food types, seafoods are also not free of food-borne pathogens and several risk factors are associated with its consumption. Regarding seafoods, there are regulatory hygienic alerts in importing countries. This paper briefly reviews the occurrence of se...
