Hypothesis
The study aims to identify the HSP70-II gene in Leishmania braziliensis and characterize its genomic organization and untranslated regions.
Conclusion
The study established the composition and structure of the HSP70 locus of L. braziliensis, showing that gene regulation does not operate by mRNA stabilization as in other Leishmania species.
Supporting Evidence
- The study identified two types of HSP70 genes in L. braziliensis.
- The 3' UTR-II has a low sequence identity when compared with this region in other Leishmania species.
- The genomic organization of the HSP70 genes in L. braziliensis resembles that found in other Leishmania species.
Takeaway
Researchers found two types of HSP70 genes in a parasite called Leishmania braziliensis, which helps it survive heat stress.
Methodology
RT-PCR and Southern blot analyses were used to map the untranslated regions and assess gene expression.
Limitations
The genomic sequence in the GeneDB database has gaps that hinder a complete understanding of the HSP70 locus organization.
