The shift of thermoneutral zone in striped hamster acclimated to different temperatures.

Here, we examined the effect of ambient temperature (Ta) on the thermal biology and energy budget in striped hamsters acclimated to cold (5°C), warm (21°C) and hot temperatures (31°C). Thermoneutral zone (TNZ) was 22.5-32.5°C, 25-32.5°C and 30-32.5°C in the cold-, warm- and hot-acclimated hamsters, respectively. The cold acclimation decreased the lower critical temperature and made the TNZ wider, and hot exposure elevated the lower critical temperature, resulting in a narrow TNZ. Within the TNZ, cold-acclimated hamsters showed a significantly higher rate of metabolism and thermogenesis than those acclimated to hot temperature. Digestive enzymes activities, including intestinal sucrase, maltase, L-alanine aminopeptidase-N and leucine aminopeptidase were higher in the cold than in the hot. The changes in metabolic rate and thermogenesis at different temperatures were in parallel with cytochrome c oxidase activity and uncoupling protein 1 gene expression of brown adipose tissue. This suggests that the shift of the lower critical temperature of TNZ is possibly associated with the rate of metabolism and thermogenesis, as well as with the digestive capacity of the gastrointestinal tract at different Ta. The upper critical temperature of TNZ may be independent of the changes in Ta. The changes of lower critical temperature of TNZ are an important strategy in adaption to variations of Ta.

A cost-effective protocol for the parallel production of libraries of 13CH3-specifically labeled mutants for NMR studies of high molecular weight proteins.

Crublet E, Kerfah R, Mas G, Noirclerc-Savoye M, Lantez V, Vernet T, Boisbouvier J.Author information Institut de Biologie Structurale Jean-Pierre Ebel, CEA, Grenoble, France.AbstractThere is increasing interest in applying NMR spectroscopy to the study of large protein assemblies. Development of methyl-specific labeling protocols combined with improved NMR spectroscopy enable nowadays studies of proteins complexes up to 1 MDa. For such large complexes, the major interest lies in obtaining structural, dynamic and interaction information in solution, which requires sequence-specific resonance assignment of NMR signals. While such analysis is quite standard for small proteins, it remains one of the major bottlenecks when the size of the protein increases. Here, we describe implementation and latest improvements of SeSAM, a fast and user-friendly approach for assignment of methyl resonances in large proteins using mutagenesis. We have improved culture medium to boost the production of methyl-specifically labeled proteins, allowing us to perform small-scale parallel production and purification of a library of (13)CH3-specifically labeled mutants. This optimized protocol is illustrated by assignment of Alanine, Isoleucine, and Valine methyl groups of the homododecameric aminopeptidase PhTET2. We estimated that this improved method allows assignment of ca. 100 methyl cross-peaks in 2 weeks, including 4 days of NMR time and less than 2 k€ of isotopic materials.

TET2 mutations, myelodysplastic features, and a distinct immunoprofile characterize blastic plasmacytoid dendritic cell neoplasm in the bone marrow.

Alayed K, Patel KP, Konoplev S, Singh RR, Routbort MJ, Reddy N, Pemmaraju N, Zhang L, Shaikh AA, Aladily TN, Jain N, Luthra R, Jeffrey Medeiros L, Khoury JD.Author information Department of Hematopathology, The University of Texas MD Anderson Cancer Center, Houston, Texas; Department of Pathology, King Saud University, Riyadh, Saudi Arabia.AbstractDistinguishing blastic plasmacytoid dendritic cell neoplasm (BPDCN) from acute myeloid leukemia (AML) is gaining increased importance because of emerging differences in therapeutic approaches, and this distinction can be problematic in bone marrow specimens. We identified retrospectively 16 patients with bone marrow involvement by BPDCN: 11 men and 5 women with a median age of 62.5 years (range, 19-86 years). Myelodysplastic changes were observed in five patients. Immunophenotypic analysis showed that the neoplastic cells were positive for CD4, CD123, TCL-1, and HLA-DR and were negative for CD3, CD8, CD13, CD19, CD34, and myeloperoxidase. Other antigens expressed by subsets of BPDCN cases included the following: CD56 (13/15; 81%), CD33 (7/10; 70%), CD7 (11/14; 69%), TdT (5/15; 33%), CD2 (5/11; 31%), CD117 (2/9; 22%), and CD5 (2/13; 15%). Conventional cytogenetic analysis showed chromosomal abnormalities in 6 of 13 (46%) cases analyzed, of which 3 cases had -13/13q-. Targeted next-generation sequencing performed on five BPDCN cases identified TET2 (ten eleven translocation 2) mutations and no other AML-associated mutations. In conclusion, BPDCN in the bone marrow has a characteristic immunoprofile (CD4+, CD56+, CD123+, and TCL-1+) and appears to be commonly associated with myelodysplastic features and a high frequency of TET2 mutations in the absence of other mutations commonly observed in AML.
