REEDLEY, CA - OCTOBER 19: Seventeen year-old Marissa Hamilton watches a friend eat during a meal at Wellspring Academy October 19, 2009 in Reedley, California. Struggling with her weight, seventeen year-old Marissa Hamilton enrolled at the Wellspring Academy, a special school that helps teens and college level students lose weight along with academic courses. When Marissa first started her semester at Wellspring she weighed in at 340 pounds and has since dropped over 40 pounds of weight in the first two months of the program. According to the Centers for Disease Control and Prevention, 16 percent of children in the US ages 6-19 years are overweight or obese, three times the amount since 1980.

Što smo deblji to naše tijelo proizvodi više bjelančevina koje inhibiraju našu sposobnost da 'trošimo' masno tkivo, pokazuje novo istraživanje objavljeno u časopisu Nature Communications.

Rezultati bi mogli utjecati na liječenje pretilosti i drugih metaboličkih poremećaja.

Većina masnih stanica u tijelu djeluje tako da uskladišti energiju i oslobađa ju kad je potrebna no neke masne stanice poznate kao adipociti funkcioniraju u procesu poznatom kao termogeneza kojom se osigurava naša toplokrvnost.

Međunarodni tim znanstvenika sa sveučilišta Cambridge u Britaniji i Toho u Japanu pokazao je da protein sLR11 pronađen u tijelu djeluje tako da potiskuje taj proces. Znanstvenici su proučavali zašto su miševi kojima manjka gen za proizvodnju toga proteina otporniji na debljanje....
