Finally, we show that RANK binds to HER2 in breast cancer cells and that enhanced RANK pathway activation alters HER2 phosphorylation status. Our data support a physical and functional link between RANK and HER2 signaling in breast cancer and demonstrate that increased RANK signaling may contribute to the development of lapatinib resistance through NF-κB activation. Whether HER2-positive breast cancer patients with tumoral RANK expression might benefit from dual HER2 and RANK inhibition therapy remains to be elucidated.

This involves an increased risk of developing mental disorders, such as (complex) post-traumatic stress (PTSD, CPTSD) and borderline personality disorder (BPD). Both within and outside of these diagnostic boundaries, complex trauma has been associated with emotional dysregulation, dissociation, distrust, interpersonal problems, and maladaptive coping behaviours, such as self-harm and suicidal behaviour. Knowledge on the devastating consequences of complex trauma has steadily increased. One of the remaining research questions is why some people develop certain psychopathological symptoms or disorders after complex trauma while others do not. Moreover, more research is needed to better understand how disorders such as BPD and CPTSD can be differentiated, both
