Exciting new research from Northwestern Medicine has discovered that inside every cell within the human body is a toxic kill code designed to trigger self-destruction if it senses a cell is turning cancerous. Across two newly published studies the scientists remarkably homed in on the exact nucleotide code underlying this mechanism and believe it may lead to an entirely novel kind of cancer treatment.

The research originally started with Marcus Peter and his team at Northwestern wondering what natural mechanisms could have developed to protect multicellular organisms from cancer before the adaptive immune system evolved. Last year, the breakthrough research first revealed a powerful ancient kill switch in the human genome that can trigger small RNA molecules (called siRNAs). These tiny assassin molecules, which are also triggered by chemotherapy, are incredibly effective at targeting and destroying cancer cells, yet the exact mechanism by which they killed the cancer cells was unclear.

               Testele de laborator, un succes

    Va putea trata mai multe tipuri de cancer

     Conform  mediafax.ro,Un medicament aflat în fază de experiment a ajutat medicii, în sfârşit, să trateze jumătate din cazurile de cancer care de obicei deveneau imune la pastile.

      Cercetătorii de la Universitatea din California, din San Francisco, au folosit un medicament în curs de dezvoltare, făcut de Revolution Medicines, care ajută la încetinirea creşterii celulelor de plâmani, piele, coloană şi pancreas, conform Dailymail.co.uk.
 
Tipurile de cancer pe care medicii speră sa le trateze sunt destul de „încăpăţânate” datorită mutaţiilor ce fac celulele să crească necontrolat.

De vreme ce experimentele pe animale au întrerupt cu succes acest proces, cercetătorii plănuiesc să expedieze medicamentul către clinici să îl încerce, ca doctorii să poată trata celulele canceroase.

   "Florentina Prisăcaru, diagnosticată cu o formă rară de cancer, are nevoie de ajutor

                               Florentina Prisăcaru
"Florentina Prisăcaru, o tânără de 24 de ani, a fost diagnosticată cu o formă rară de cancer, iar pentru a învinge lupta cu boala are nevoie de ajutorul fiecăruia dintre noi.

   Florentina Prisăcaru, recent absolventă a Masteratului Comunicare Audio-Video, din cadrul Școlii Naționale de Studii Politice și Administrative, a fost diagnosticată cu o formă rară de cancer, sarcom cu celule clare de părți moi. Pentru a putea supraviețui, Florentina are nevoie de ajutorul nostru. 

După îndelungi căutări și vizite la medici din Franța și Austria, Florentina a descoperit un tratament experimental în Statele Unite, California. Pentru a urma acest tratament de lungă durată, tânăra are nevoie de o sumă enormă de bani, aproximativ 500.000 de dolari.

New research by a team of Australian scientists has unexpectedly revealed a novel anti-obesity drug. Initially working to create a drug that prevents insulin resistance, the researchers discovered in early animal tests that it instead prevented the animals from depositing and storing fat.

The long-term collaborative project involved scientists from the Centenary Institute and UNSW Sydney. The original plan was to find a way to inhibit insulin resistance, a key dysfunction that leads to a variety of metabolic diseases including type 2 diabetes.

New antibiotic candidates were inside us all along


A new antibiotic candidate has been found – and it's already inside the human body

   With bacteria rapidly evolving resistance to our best antibiotics, scientists are searching high and low for new ones. In recent years promising drug candidates have turned up in some unexpected places, like rattlesnake venom, platypus milk and tobacco flowers – and now, already inside the human body. Researchers from MIT and the University of Naples Federico II have found that a potent peptide normally used for digestion has strong antimicrobial effects, and could form the base of new drugs.
