Role of c-fos gene in vasoactive intestinal peptide promoted synthesis of pulmonary surfactant phospholipids.

We previously reported that vasoactive intestinal peptide (VIP) promoted synthesis of phosphatidylcholine (PC) in alveolar type II (ATII) cells. But the intracellular mechanism for this effect was unknown. In this work, we investigated the intracellular signal transduction pathway for VIP promoted synthesis of PC, the major lipid component of pulmonary surfactant (PS), by using an antagonist of VIP receptors, inhibitor of protein kinase C (PKC) and antisense oligonucleotides (AS-ODN) for c-fos oncogene. Our results showed that: 1 in circle [D-P-Cl-Phe(6)-Leu(17)]-VIP (10(-6) mol/l), an antagonist of VIP receptors, could decrease the quantity of [(3)H] choline incorporation, microsomal choline-phosphate cytidylyltransferase (CCT) mRNA expression and CCT activity induced by VIP (10(-8) mol/l) in cultured lung explants to the control levels; 2 in circle VIP (10(-8) mol/l) upregulated c-Fos protein expression in ATII cells. AS-ODN for c-fos oncogene (9x10(-6) mol/l) could block the elevation of [(3)H] choline incorporation, microsomal CCT mRNA expression and CCT activity induced by VIP in cultured lung explants and in ATII cells; 3 in circle H7 (10(-5) mol/l), a PKC inhibitor could also reduce VIP induced [(3)H] choline incorporation, microsomal CCT mRNA expression and CCT activity in cultured lung explants and in ATII cells. These results demonstrated that VIP receptors, PKC and c-Fos protein played important roles in the signaling pathway through which VIP promoted the synthesis of PC.

[Congenital hyperinsulinism: a difficult and complicated case study].

This paper reported a case of congenital hyperinsulinism and reviewed the relevant literatures regarding to the etiology, pathogenesis, clinical and pathological features, diagnosis and treatment of this disorder. The baby (male), with gestational age of 36 weeks and birth weight 4,200 g, was delivered by caesarean section. It presented with hypoglycemia immediately after birth (0.8 mmol/L). Through the course of the disease, the baby's blood sugar manifested with 1.2-2.8 mmol/L although glucocorticoid was administered. 10% glucose solutions were intravenously infused at a speed of 10-17 mg/(kg x min) for this patient to retain a stable blood sugar level. The plasma insulin level was 24.13 U/L and blood sugar level was 1.5 mmol/L on day 30 of his life. The ratio of plasma insulin (U/L) and plasma glucose (mg/dL) was 0.89. These results suggest an inappropriate insulin secretion resulting in persistent hypoglycemia in this baby and so it was definitely diagnosed with congenital hyperinsulinism.
