A 52-year-old woman with a meningioma was transferred to our hospital due to abdominal mass and hypoglycemic symptoms. Abdominal computed tomography confirmed thickening of the gallbladder wall, with a 10 x 7 cm mass occupying the right inferior and medial segment of the liver. Her fasting glucose was low on hypoglycemic attack, with a serum insulin level of 173 mIU/ml (normal; 5~20 mIU/ml). Other radiologic tests, including portal venous sampling, did not localize the insulin producing lesion in the pancreas. The preoperative diagnosis was one of a malignant gallbladder tumor infiltrating the liver, with the possibility of nesidioblastosis; therefore, extended cholecystectomy and distal pancreatectomy were performed as the frozen biopsy of the pancreas confirmed an increase of cells in the islet of Langerhans. In permanent specimens, the pancreas showed normal histology and the gallbladder lesion showed a neuroendocrine carcinoma combined with an adenocarcinoma, with positive immunostaining for CD56, chromogranin A and synaptophysin. The special immunostaining for insulin was positive. The patient was in a glucose intolerant state with administration of small dose of oral hypoglycemic agents after operation. Metastases of the lesion to the skull and spine were observed two months after surgery. We report non-islet cell insulin releasing neuroendocrine carcinoma, combined with an adenocarcinoma of the gallbladder, presenting with hypoglycemic symptoms

OBJECTIVE: Comparison of protein expressions by two-dimensional gel electrophoresis (2-DE) in normal cervix and squamous cell carcinoma tissues in Korean women. METHODS: Normal cervix and squamous cell carcinoma tissues were solubilized with 2-DE buffer and the first dimension of PROTEAN IEF CELL, isoelectric focusing (IEF), was performed using pH3-10 linear IPG strips of 17 cm. And then running 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and sliver stain. Scanned image was analyzed using PDQuest 2-D softwareTM. Protein spot spectrum was identified by assisted laser desorption/ionization-time of fighting (MALDI-TOF) and the protein mass spectrum identifications were performed by searching protein databases of Swiss-prot/TrEMBL, Mascot and MS-FIT. RESULTS: We found 9 up-regulation proteins (Alpha enolase, Keratin 19 type I, Keratin 20 type I, Keratin 13 type I, beta-actin, Aflatoxin B1 aldehyde reductase 1, Annexin A2, Squamous cell carcinoma antigen 2, unknown), 7 down-reguation proteins (Annexin 1, Myosin regulatory light chain 2, 14-3-3 protein epsilon, Heat shock 27 kDa protein, Hypothetical protein (DKFZP434C1715), Tumor necrosis factor receptor superfamily member 13B, Smoth muscle protein 22-alpha) and 6 up and down-regulation proteins (Tropomyosin 1, Tropomyosin 2, Tropomyosin 3, Serine (or cysteine) proteinase inhibitor, Phosphatidylinositol transfer protein alpha isoform, Src homology 3 domain-containing protein HIP-55) between normal cervix and squamous cell carcinoma cell tissues. CONCLUSION: 2-DE offers total protein expressions between normal cervix and squamous cell carcinoma cell tissues, and searching of differently expressed protein for the diagnostic markers of squamous cell carcinoma tissue.

OBJECTIVE: To know the effect of adenosine 5'-triphosphate (ATP) on intracellular calcium level and cell proliferation in cervical cancer cells. METHODS: Study design: Four different human cervical cancer cell lines (Caski, C33A, HeLaS3 and SiHa) were used in this study. The change of intracellular calcium level, cell proliferation and the activity of proliferation- and calcium-related transcription factors by extracellular ATP were examined in these cell lines. RESULTS: Extracellular ATP induced calcium mobilization, cell proliferation and the activation of NF-kappa B in all cell lines used. CONCLUSION: These results suggest that calcium mobilization and NF-kappa B dependent signaling pathway play an important role in the cell proliferation by ATP in cervical cancer.
