Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons. Since...
Study uncovers how cancers resist targeted treatment
by Institute of Cancer Research Fig. 1: Identification of trapped PARP1-interacting proteins. a, Schematic describing the identification of trapped PARP1 protein–protein interactomes via RIME or proximity labeling linked to mass spectrometry. The cells were exposed to either PARPi + MMS (to enable trapping) or MMS (no trapping) for 1 h, after which PARP1-interacting/proximal proteins were identified by mass...
Pill Not Enough for ‘Sexual Problems’ Female Cancer Patients Face
Roxanne Nelson RN, BSN January 05, 2022 The antidepressant bupropion failed to improve sexual dysfunction in female cancer survivors, according to new findings.
