Summary: Human exposure to aflatoxins in food can lead to acute stunting in children, liver cancer, and death. The severity of aflatoxin contamination depends on the type of Aspergillus fungus infecting the crops. Evaluating the ability of non-aflatoxigenic chemotypes to reduce aflatoxin levels produced by aflatoxigenic strains could be crucial in mitigating field contamination of crops with aflatoxins.

Summary: The bifunctional gene bioDA in Aspergillus flavus plays a crucial role in biotin biosynthesis and can complement E. coli mutants. The gene product is mainly localized to the mitochondria, unaffected by environmental stresses, and its deletion impairs biotin production and reduces pathogenicity. This study sheds light on biotin biosynthesis in A. flavus and identifies potential antifungal drug candidates.

Summary: L-methionine gamma-lyase (MGL) was purified from A. fumigatus using heat treatment and gel filtration, resulting in 3.04-fold purification and 73.9% enzymatic recovery. The purified MGL showed a molecular mass of approximately 46 KDa. It exhibited maximum activity at pH 7 and stability within the pH range of 5.0-7.5. The enzyme had the highest catalytic activity at 30-40°C and remained stable up to 40°C. It was significantly inhibited by several metal ions and chemical reagents. MGL demonstrated anticancer activity against Hep-G2 and HCT116 cell lines at low concentrations. Overall, A. fumigatus MGL possesses favorable catalytic properties and potential for enzymotherapy.

Summary: This study reports the antifungal and AFB1 inhibitory effects of a formulation CIM developed using a mixture of essential oils and methyl anthranilate. The mechanism of action was explored through biochemical, molecular docking, and RT-PCR analysis. Furthermore, nanoencapsulation of CIM was prepared and shown to effectively control A. flavus and AFB1 contamination, and protect the active ingredients of herbal raw materials without affecting their sensory properties. Overall, this research provides a green chemical agent to protect the biodeterioration of active ingredients caused by toxigenic species of A. flavus.

Summary: Peripheral myelin protein (PMP22) misfolding is identified as a key factor in various peripheral neuropathies. Mutant forms of PMP22 exhibit differences in stability and propensity to form homodimeric complexes compared to wild-type protein. The formation of PMP22 dimers from destabilized monomers is proposed as a key element in PMP22 mistrafficking, based on combined findings from native ion mobility-mass spectrometry and cellular data.
