Researchers turn a deadly fungus into potent cancer-fighting compound

Penn-led researchers have turned a deadly fungus into a potent cancer-fighting compound. After isolating a new class of molecules from Aspergillus flavus, a toxic crop fungus linked to deaths in the excavations of ancient tombs, the researchers modified the chemicals and tested them against leukemia cells.

Targeting ST6Gal-I shows promise in reducing Alzheimer’s disease pathology

A recent study published in Engineering has provided novel insights into the involvement of α2,6-sialylation in Alzheimer's disease (AD), revealing that the ablation of α2,6-sialyltransferase-I (ST6Gal-I), an enzyme responsible for α2,6-sialylation, can downregulate BACE1 expression and suppress the production of amyloid-β42 (Aβ42) plaques, which are hallmarks of AD.

Estrogen-responsive cells found to heighten gut pain in females

Researchers uncovered how estrogen heightens gut sensitivity in females by activating PYY-secreting L-cells, which stimulate serotonin release from EC cells. This paracrine circuit intensifies pain signaling and may explain the sex bias in conditions like IBS.

New computational tool uncovers hidden genetic mutations in proteins

Scientists at UCLA and the University of Toronto have developed an advanced computational tool, called moPepGen, that helps identify previously invisible genetic mutations in proteins, unlocking new possibilities in cancer research and beyond.

Short peptides show promise in blocking breast cancer metastasis

A surgeon can excise breast cancer from the body, but even the most skilled scalpel may not be able to remove every cell - especially when the cells have spread from the original disease site elsewhere in the body.

New family of antibiotics derived from the body's own proteins

A team of scientists led by the UAB has identified a new type of antimicrobial peptides (AMPs) found in human proteins that are capable of selectively eliminating multidrug-resistant bacteria, particularly of the gram-negative type, responsible for serious hospital acquired infections.

Insulin resistance in the brain may link Alzheimer’s and epilepsy

Researchers at the University of São Paulo (USP) in Brazil have succeeded in showing, in an animal model, that the process of insulin resistance in the brain affects both Alzheimer's disease and epilepsy and may be a linking factor between the two diseases.

New discovery may help explain why some people infected with CHIKV develop severe joint pain

Chikungunya virus (CHIKV) is a mosquito-borne pathogen that has been identified in more than 110 countries around the world. The virus typically causes flu-like symptoms, but it can also trigger chronic, severe joint pain in some people.

Peptide nanostructures block amyloid buildup and boost neuron survival in lab tests

Researchers developed trehalose-functionalized peptide amphiphiles (TPAs) that self-assemble into supramolecular nanostructures and demonstrated these TPAs can inhibit amyloid beta aggregation. In vitro, TPAs significantly improved survival of human neurons exposed to amyloid-induced neurotoxicity, suggesting therapeutic potential for neurodegenerative diseases.
