A child, aged 6 years 3 months, with a triglyceride storage disorder in peripheral adipose tissue, microcephaly, and gross emaciation has been studied at autopsy. The mean triglyceride content of adipocytes in hand and foot was 0.17 +/- 0.02 mug/cell and 0.18 +/- 0.02 mug/cell. Adipocytes from abdominal tissue were small, irregular, and difficult to measure accurately, reflecting the degree of cachexia. Basal tissue contents of cyclic AMP and release of glycerol and fatty acid from peripheral tissue of the child were in the same range as adult tissues. None of these measurements, however, were increased by incubation with isoprenaline (10(-5 M), compared to a three- to seven-fold increment in adult subcutaneous tissues and to a four- to ten-fold increment of glycerol and cyclic AMP in peripheral adipose tissue of a control child aged 10 years. We postulate that the proband may have had a defect of adenyl cyclase or catecholamine receptor, which has a role in the abnormal storage of triglyceride in peripheral adipose tissue.

Cachexia in cancer is characterized by progressive emaciation involving depletion of host adipose tissue stores, the molecular mechanism of which remains largely unknown. In this study, we have attempted to clarify the biologic characteristics of lipid-depleting factor in a mouse cachexia model. Utilizing differentiated 3T3-L1 adipocytes, we established an assay method quantifying the lipid-depleting activity in plasma derived from colon-26-inoculated mice and then analyzed the associated molecular mechanism. Injection (s.c.) of a mouse colon adenocarcinoma cell line, colon-26 clone 20, induced cachexia, as evidenced by progressive weight loss. Addition of clone 20-derived cachexigenic, but not clone 5-derived noncachexigenic, plasma to the culture medium of differentiated 3T3-L1 adipocytes reduced the TG content in cultured cells. The ability of the introduced plasma to induce TG loss in 3T3-L1 cells paralleled the body weight changes of tumor-inoculated host mice. Clone 20 plasma, but not clone 5 plasma or recombinant IL-6, elicited lipolytic activity, which induced glycerol release from 3T3-L1 cells. Addition of clone 20 plasma to cultured 3T3-L1 adipocytes reduced TG synthesis from [(14)C]-glucose compared to clone 5 plasma, indicating that the lipid-depleting activity resulting from addition of clone 20 plasma depended not only on induction of lipolysis but also on inhibition of lipogenesis. Addition of clone 20 plasma to cultured 3T3-L1 adipocytes reduced the quantity of mature SREBP-1 in the nucleus of 3T3-L1 cells without affecting PPAR-gamma and C/EBP-alpha. Although TNF-alpha induced apoptosis in 3T3-L1 cells, clone 20 plasma did not. These results suggest that the lipid-depleting factor in clone 20 plasma is different from either IL-6 or TNF-alpha, and that this factor interfered with not only lipolysis but also lipogenesis through SREBP-1 of 3T3-L1 adipocytes.

Serum biochemical analysis was undertaken to study the pathophysiological details of emaciation disease of the tiger puffer fish Takifugu rubripes (Temminck and Schlegel). Serum parameters were measured by biochemical analysis using automated dry chemistry and gas chromatography/mass spectrometry (GC/MS). Serum concentrations of albumin, amylase, calcium, creatinine, glucose and total protein were significantly lower in the emaciated fish when compared with those of normal fish. Regression analyses found close correlation between concentrations of total protein, albumin, amylase, glucose and progress of the disease. In contrast, serum alanine aminotransferase increased significantly in emaciated fish indicating liver function disorder. Further, GC/MS metabolic profiling of the puffer serum showed that the profile of the emaciated fish was distinct to that of non-infected control. The serum content of amino acids including glycine, 5-oxo-proline and proline, and ascorbic acid, fumaric acid and glycerol increased significantly in serum in moderately emaciated fish. The serum glucose, linolenic acid and tyrosine level decreased significantly in the late phase of the disease. Our results clearly show that prolonged intestinal damage caused by myxosporean infection impairs absorption of nutrients, resulting in extreme emaciation.
