The malignant phenotype of small cell lung cancer (SCLC) cells critically relies on the autocrine stimulation of G12/13- and Gq/11-coupled neuropeptide receptors. By this means, G12/13- and Gq/11-dependent signalling pathways are constitutively activated in these cells. While Gq/11-dependent signalling has been shown to promote proliferation of SCLC cells, the role of signalling pathways via G12/13 is still elus...

Head and neck paragangliomas (HNPGLs) are a type of neuroendocrine tumour. They arise from the sympathetic ganglia and can be either sporadic or due to hereditary syndromes (up to 40%). Most HNPGLs do not produce significant amounts of catecholamines1. Often, HNPGLs are detected in late stages due to compression or infiltration of cranial structures1. We report a case of a paraganglioma of the basis cranii due to somatic variants of SDHB (succinate dehydr...
