RESUMO
In this study, we evaluated the toxicological and antiproliferative effects of B.â glabra Choisy bract extract (BGCE) in its free and loaded into liposomes forms administered to C.â elegans mutants with let-60 gain-of-function (gf). Our results demonstrated that the concentration up to 75â µg CAE/mL of BGCE was safe for the worms. Notably, we developed BGCE-loaded liposomes to extend the pharmacological window up to 100â µg CAE/mL without toxicity. In addition, the extract and liposomes reduced the number and area of the multivulva formed in let-60 gf mutants. There was also an increase in the apoptotic signaling in the germline cells and increased longevity mediated through DAF-16 nuclear translocation with GST-4 activation in the treated animals. Our findings demonstrated that the BGCE-loaded liposomes possess antitumoral effects due to the activation of the apoptotic signaling and DAF-16 nuclear translocation.
