Oncogenic activation of p185neu stimulates tyrosine phosphorylation in vivo.

p185, the product of the neu/erbB2 proto-oncogene, is oncogenically activated by a point mutation that substitutes glutamic acid for valine in the transmembrane domain of the protein. We have found that the transforming form of p185 differs from its normal counterpart in inducing increased tyrosine phosphorylation of other proteins in vivo and in having a much shorter half-life. These results support the model that the transforming p185 resembles a ligand-activated receptor.

Effects of parathyroid hormone and calcitonin on carbonic anhydrase location in osteoclasts of cultured embryonic chick bone.

The ultrastructural location of carbonic anhydrase has been examined in osteoclasts of cultured embryonic chick metatarsi. In untreated cultures and in those to which parathyroid hormone (PTH) was added, the enzyme was found in close association with the plasma membrane of the ruffled border. After brief calcitonin treatment (10 min) the ruffled border disappeared and the association of carbonic anhydrase with the plasma membrane was diminished. The results indicate that the hormones employed act directly on embryonic bone to alter osteoclast structure and the intracellular location of carbonic anhydrase.

CT diagnosis of ileal diverticulitis.

The preoperative diagnosis of ileal diverticulitis has been reported during small-bowel series when inflammatory changes are associated with ileal diverticula. Previous CT reports of this entity have failed to establish the specific diagnosis preoperatively. We report the CT findings in a patient with right lower quadrant pain that enabled the specific diagnosis of ileal diverticulitis to be made.
