Recent discoveries from Australian research claims that the tobacco plant has cancer healing properties. La Trobe University scientists’ latest breakthrough claims that the tobacco plant may well be healing rather than harmful. Australian researchers suggest that it could be a strong weapon in the battle against cancer. More specifically, they detected a molecule in the flower of the plant that has the ability to identify and destroy cancer. In simple terms, the molecule targets cancer cells and rips it open. The molecule is found in the flower of ornamental tobacco plants, which is the same family used for commercial purposes. According to lead researcher Dr. Mark Hullett, the discovery is somewhat ironic. Nevertheless, it is a “welcome discovery”. It is also worth noting that the molecule does little damage to healthy cells while targeting cancerous ones. The molecule, known as NAD1, will next be taken for pre-clinical analyses in order to pinpoint the role of it in the treatment of cancer. At the moment, pre-clinical work is being done by a biotechnology company in Melbourne. So far, the first few trials have indicated promising outcomes. Present-day cancer therapies tend to be indiscriminate. On the contrary, NAD1 does little to no harm on healthy cells. Therefore, researchers are confident that there is potential for this breakthrough to translate to therapeutic use in humans. The universal defence process of this discovery has also been tested that indicates that it may potentially be harnessed for other therapeutic uses. For instance, antibiotic treatment for microbial infections. This discovery is a product of the multidisciplinary effort and assistance from scientists from Dr. Hullet’s cancer biology laboratory and Dr. Marc Kvansakul’s laboratory at La Trobe University.

DUHAN UBIJA STANICE RAKA U LJUDSKOM TIJELU Studija provedena na Sveučilištu La Trobe pokazala je kako se obrambeni mehanizmi duhana mogu iskoristiti za ubijanje stanica raka u ljudskom tijelu. Znanstvenici s Instituta za molekularnu biologiju La Trobe identificirali su molekulu u cvijetu ukrasnog duhana, koja se bori protiv gljivica i bakterija, no ima i sposobnost otkriti i uništiti stanice raka, prenose mediji. Ova molekula nazvana je NaD1, a funkcionira na način da formira strukture slične kliještima, koje prijanjaju na lipide koji se nalaze u membrani stanica raka i otvaraju je, što na kraju dovodi do toga da stanica izbacuje svoje dijelove i potom eksplodira. Vodeći autor studije Mark Hulett smatra da bi se ovo otkriće moglo iskoristiti za borbu protiv raka. „Ironično je da je ovakav obrambeni mehanizam protiv raka pronađen upravo u duhanu, no bez obzira na to odakle potječe, ovo je dobrodošlo otkriće”, kaže Hulett. „Sljedeći je korak provesti pretklinička ispitivanja kako bi se doznalo koju ulogu NaD1 ima u liječenju raka. Dosadašnje preliminarne studije izgledaju obećavajuće. Vjerujemo da bi se ovo otkriće moglo iskoristiti u svrhu liječenja ljudi.” Jedan od najvećih problema s trenutnim terapijama protiv raka je to što stradavaju i zdrave stanice, no, kako je otkriveno, molekula NaD1 djeluje samo na stanice raka, a zdrave stanice ostavlja netaknutima. Znanstvenicima su dosad bile poznate molekule kojima se biljke i životinje bore protiv različitih mikroorganizama, no dosad nisu znali na koji se točno način bore s njima. Osim raka, ovaj obrambeni mehanizam mogao bi biti iskorišten i za brojne druge oblike liječenja, poput antibiotske terapije protiv bakterijskih infekcija. Udarno tim, izvor: Agroeko
