Huntington's disease (HD) is a rare neurodegenerative disease caused due to aggregation of Huntingtin (HTT) protein. This study involves the cloning of 40 DnaJ chaperones from Drosophila, and overexpressing them in yeasts and fly models of HD. Accordingly, DnaJ chaperones were catalogued as enhancers or suppressors based on their growth phenotypes and aggregation properties. 2 of the chaperones that came up as targets were CG5001 and P58IPK. Protein aggregation and slow growth phenotype was rescued in yeasts, S2 cells, and Drosophila transgenic lines of HTT103Q with these overexpressed chaperones. Since DnaJ chaperones have protein sequence similarity across species, they can be used as possible tools to combat the effects of neurodegenerative diseases.

Heat shock proteins (Hsps) are highly conserved molecular chaperones with essential roles against biotic and abiotic stressors. A large set of co-chaperons comprising J-domain proteins (DnaJs) regulate the ATPase cycle of Hsp70s with Hsp90s, together constituting a dynamic and functionally versatile network for protein folding/unfolding and regulation. Marine bivalves could accumulate and tolerate paralytic shellfish toxins (PSTs), the well-noted neurotoxins generated during harmful algal blooms.

Environmental chemicals and toxins are known to impact human health and contribute to cancer developments. Among these, genotoxins induce genetic mutations critical for cancer initiation. In the liver, proliferation serves not only as a compensatory mechanism for tissue repair but also as a potential risk factor for the progression of premalignant lesions.

Background: Bacillus subtilis is widely used for industrial enzyme production due to its capacity to efficiently secrete proteins. However, secretion efficiency of enzymes varies widely, and optimizing secretion is crucial to make production commercially viable. Previously, we have shown that overexpression of the xylanase XynA lowers expression of Clp protein chaperones, and that inactivation of CtsR, which regulates and represses clp transcription, increases the production of XynA.

Trypanosoma cruzi is a protozoan parasite that causes Chagas disease. Globally 6 to 7 million people are infected by this parasite of which 20-30% will progress to develop Chronic Chagasic Cardiomyopathy (CCC). Despite its high disease burden, no clinically approved vaccine exists for the prevention or treatment of CCC.
