Primary Institution: The University of Calgary
Hypothesis
The expression patterns of the 23 murine Prolactin/Placental Lactogen-related genes are not influenced by their genomic positions.
Conclusion
The study found that no two family members of the Prolactin gene family have the same expression pattern, and many are expressed in multiple trophoblast cell types.
Supporting Evidence
- Only minor differences were observed among strains of mice regarding gene expression.
- Most genes are expressed in multiple trophoblast cell subtypes.
- Bioinformatic analysis identified conserved transcription factor binding sites shared by genes in the same trophoblast subtype.
Takeaway
This study looked at how certain genes related to the Prolactin hormone work in mice during pregnancy, finding that each gene acts differently and is important for different parts of the placenta.
Methodology
The study used northern blot and in situ hybridization techniques to analyze gene expression in placentas from three different mouse strains at various gestational stages.
Limitations
The study could not fully discriminate between closely related gene family members due to their similarities.
Participant Demographics
Mice from three genetic strains were used in the study.
