Authors Dirk Smeesters , Thomas Mussweiler , and Naomi Mandel researched the methods individuals with different body mass indexes felt when they were exposed to thin or weighty media models. Our research confirms earlier research that found that regular body mass index females’ self-esteem can change upwards or downwards depending on the model they face, the authors write. Regular BMI females have higher degrees of self-esteem when exposed to moderately thin models and extremely heavy models . However, they have lower levels of self-esteem when subjected to moderately heavy models and intensely thin versions .

They found that blocking Nodal signaling decreased melanoma cell invasiveness also, as well as cancer cell colony formation and tumor-forming capability. Strikingly, nodal inhibition promoted the reversion of these cells toward a normal epidermis cell type. Like embryonic stem cells, malignant tumor cells similarly send and receive molecular cues during development that promote tumor metastasis and growth, or cancer spread.
