HNF1A induces glioblastoma by upregulating EPS8 and activating PI3K/AKT signaling pathway.

Despite the exact biological role of HNF1 homolog A (HNF1A) in the regulatory mechanism of glioblastoma (GBM), the molecular mechanism, especially the downstream regulation as a transcription factor, remains to be further elucidated. Immunohistochemistry was used to detect the expression and clinical relevance of HNF1A in GBM patients. CCK8, TUNEL, and subcutaneous tumor formation in nude mice were used to evaluate the effect of HNF1A on GBM in vitro and in vivo.

An unusual tale of rat-bite fever endocarditis.

A 49-year-old man presented to our department with an acute history of right leg tenderness, rash, swelling and fever. CT of the chest, abdomen and pelvis and a transoesophageal echocardiogram confirmed the diagnosis of mitral valve infective endocarditis with distal splenic emboli. Positive blood cultures revealed the causative organism to be Streptobacillus moniliformis.
