Rebound Growth of Infantile Hemangiomas after Propranolol versus Atenolol Treatment: A Retrospective Study.

Introduction: Propranolol is the first-line treatment for complicated infantile hemangioma (IH). Rebound growth following propranolol discontinuation is reported in 6-25% of patients. Atenolol is considered an effective alternative to propranolol.

Blood-brain barrier dysfunction and decreased transcription of tight junction proteins in epileptic dogs.

Background: Epilepsy in dogs and humans is associated with blood-brain barrier (BBB) dysfunction (BBBD), which may involve dysfunction of tight junction (TJ) proteins, matrix metalloproteases, and astrocytes. Imaging techniques to assess BBB integrity, to identify potential treatment strategies, have not yet been evaluated in veterinary medicine.

Hypothesis: Some dogs with idiopathic epilepsy (IE) will exhibit BBBD.

TAZ facilitates breast tumor growth by promoting an immune-suppressive tumor microenvironment.

The core Hippo pathway module consists of a tumour-suppressive kinase cascade that inhibits the transcriptional coactivators Yes-associated protein (YAP) and WW domain-containing transcription regulator protein 1 (WWTR1; also known as TAZ). When the Hippo pathway is downregulated, as often occurs in breast cancer, YAP/TAZ activity is induced. To elaborate the roles of TAZ in triple-negative breast cancer (TNBC), we depleted Taz in murine TNBC 4T1 cells, using either CRISPR/Cas9 or small hairpin RNA (shRNA).
