Summary
Programmed cell death protein 2 like (PDCD2L) is crucial for embryonic development, not male fertility. Knockout mice and fruit flies lacking PDCD2L exhibit developmental lethality, indicating its conserved role in development.
Area of Science:
- Developmental Biology
- Genetics
- Reproductive Biology
Background:
- Globozoospermia, a rare infertility cause, is linked to globozoospermia gene mutations.
- Previous whole exome screening identified homozygous mutations in PDCD2L as a potential cause of globozoospermia.
Purpose of the Study:
- To investigate the role of PDCD2L in male fertility using a knockout mouse model.
- To determine the function of PDCD2L in germ cells using Drosophila melanogaster.
Main Methods:
- Generated Pdcd2l knockout mice to assess male fertility.
- Utilized Drosophila melanogaster to study the role of the PDCD2L ortholog (trus) in germ cells via knockdown experiments.
Main Results:
- Pdcd2l knockout mice exhibited embryonic lethality, with embryos resorbed between embryonic days 12.5-17.5.
- Heterozygous Pdcd2l males showed normal fertility, comparable to wildtype males.
- Germ cell-specific knockdown of trus in Drosophila did not impact male fertility, despite global knockdown causing larval lethality.
Conclusions:
- PDCD2L is essential for embryonic development, not male fertility.
- The data suggest an evolutionarily conserved role for PDCD2L in development across species.

Overview of Cell Death
8.8K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Abnormal Proliferation
5.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
