Abstract (croatian)
U radu su ispitani antiproliferativni, antimikrobni i antioksidacijski učinci medljikovaca jele (Abies alba Mill.) prikupljenih s planinskog područja Hrvatske (Gorski kotar) a u svrhu potencijalne primjene umjesto standardnih antibiotika i kemoterapeutika. Preživljavanje stanica, annexin V test i protočna citometrijska analiza poslužili su za procjenu antiproliferativnog učinka na indukciju apoptoze i smrti humanih tumorskih staničnih linija: HeLa, MCF-7, SW620, CFPAC-1, MIA PaCa-2 i normalnih diploidnih humanih fibroblasta (BJ). Antimikrobna je aktivnost testirana na različitim sojevima bakterija Staphylococcus i Acinetobacter uporabom difuzijske i mikrodilucijske metode. DPPH˙ testom određena je sposobnost uklanjanja radikala, dok je matematičkim modelima proučavana kinetika inhibicije DPPH˙. Uočen je antiproliferativni učinak na sve ispitivane stanične linije kao i na normalne diploidne fibroblaste (BJ), kolorektalni adenokarcinom (SW620, metastatski) i adenokarcinom epitela dojke (MCF-7, metastatski). Mehanizmi antiproliferativnog učinka uključuju nakupljanje stanica u sub-G1 fazi u svim ispitivanim stanicama te indukciju apoptoze osobito u SW620 i MCF-7 stanicama. Antibakterijski testovi pokazuju da su rezistentni sojevi obaju bakterija, uključujući i multirezistentni soj A. baumannii ATCC® BAA-1605™, bili osjetljivi na sve ispitane uzorke meda. Proučavanjem kinetike uklanjanja radikala dokazano je da antioksidansi prisutni u medu posjeduju različite sposobnosti hvatanja radikala, da reagiraju s njima različitim brzinama i time uzrokuju dva stupnja reakcije. Rezultati istraživanja pokazuju da hrvatski medljikovac ima terapeutski potencijal zbog snažne biološke aktivnosti te može služiti u zaštiti ljudskog zdravlja.
Abstract (english)
The paper examines the antiproliferative, antimicrobial and antioxidative effects of fir (Abies alba Mill.) honeydew honey from mountain region of Croatia (Gorski kotar) as a potential replacement for standard antibiotics and chemotherapeutic agents. Cell viability, annexin V assay and flow cytometry analysis served to analyse the antiproliferative effect on, apoptosis induction in and cell death of cancer cell lines: HeLa, MCF-7, SW620, CFPAC-1, MIA PaCa-2 and normal diploid human fibroblasts (BJ). Antimicrobial activity was tested against Staphylococcus and Acinetobacter strains by agar well diffusion and microdilution assays. The DPPH˙ assay determined the radical scavenging activity, while mathematical models helped to evaluate the kinetic data of DPPH˙ inhibition. Antiproliferative effect on all tested cell lines and the prominent effect on normal diploid human fibroblasts (BJ), colorectal adenocarcinoma (SW620, metastatic) and breast epithelial adenocarcinoma (MCF-7, metastatic) was observable. The mechanisms of antiproliferative effect included accumulation of cells in the sub-G1 phase in all tested cells and induction of apoptosis in SW620 and MCF-7 cells predominantly. The antibacterial assays showed that antibiotic resistant strains of both bacteria, including multi-resistant strain A. baumannii ATCC® BAA-1605™, were sensitive to all tested honey samples. Radical scavenging assay suggests that antioxidants present in the honey possess different radical suppressing abilities and that they react at different rates with radicals, thereby causing two steps of reaction. The results of the study indicate that Croatian fir honeydew honey has a therapeutic potential due to the strong biological activity and can serve to protect human health.
