The imprinted Igf2-Igf2r axis is critical for exosome biogenesis during the early development of bovine placenta.

Insulin-like growth factor 2 (IGF2) is essential for cell growth and differentiation and functions through the IGF2 receptor (IGF2R) to regulate embryonic and placental development. Exosomes that are synthesized and released from cells and play important roles in embryogenesis and placental development rely on the IGF2R for sorting and transport. However, the role of the imprinted Igf2-Igr2r axis and exosomes in the co-regulation of early placental development remains unknown.

Non-cirrhotic portal fibrosis/idiopathic portal hypertension: APASL recommendations for diagnosis and management.

Since the Asian Pacific Association for the Study of the Liver (APASL) published guidelines on non-cirrhotic portal fibrosis/idiopathic portal hypertension in 2007, there has been a surge in new information, especially with the introduction of the term porto-sinusoidal vascular disorder (PSVD). Non-cirrhotic intra-hepatic causes of portal hypertension include disorders with a clearly identifiable etiology, such as schistosomiasis, as well as disorders with an unclear etiology such as non-cirrhotic portal fibrosis (NCPF), also termed idiopathic portal hypertension (IPH). This entity is being increasingly recognized as being associated with systemic disease and drug therapy, especially cancer therapy.
