TL;DR: High-resolution, genome-wide copy number analysis coupled with gene-expression profiling provides genetic evidence that the DLBCL subtypes are distinct diseases that use different oncogenic pathways.
Abstract: Gene-expression profiling has been used to define 3 molecular subtypes of diffuse large B-cell lymphoma (DLBCL), termed germinal center B-cell-like (GCB) DLBCL, activated B-cell-like (ABC) DLBCL, and primary mediastinal B-cell lymphoma (PMBL). To investigate whether these DLBCL subtypes arise by distinct pathogenetic mechanisms, we analyzed 203 DLBCL biopsy samples by high-resolution, genome-wide copy number analysis coupled with gene-expression profiling. Of 272 recurrent chromosomal aberrations that were associated with gene-expression alterations, 30 were used differentially by the DLBCL subtypes (P < 0.006). An amplicon on chromosome 19 was detected in 26% of ABC DLBCLs but in only 3% of GCB DLBCLs and PMBLs. A highly up-regulated gene in this amplicon was SPIB, which encodes an ETS family transcription factor. Knockdown of SPIB by RNA interference was toxic to ABC DLBCL cell lines but not to GCB DLBCL, PMBL, or myeloma cell lines, strongly implicating SPIB as an oncogene involved in the pathogenesis of ABC DLBCL. Deletion of the INK4a/ARF tumor suppressor locus and trisomy 3 also occurred almost exclusively in ABC DLBCLs and was associated with inferior outcome within this subtype. FOXP1 emerged as a potential oncogene in ABC DLBCL that was up-regulated by trisomy 3 and by more focal high-level amplifications. In GCB DLBCL, amplification of the oncogenic mir-17-92 microRNA cluster and deletion of the tumor suppressor PTEN were recurrent, but these events did not occur in ABC DLBCL. Together, these data provide genetic evidence that the DLBCL subtypes are distinct diseases that use different oncogenic pathways.

TL;DR: Gerhard Bringmann's research interests focus on the field of analytical, synthetic, and computational natural product chemistry, i.e., on axially chiral biaryls, which is characterized by a broad structural diversity.
Abstract: Intellectual curiosity has always been one of the major driving forces leading to new advances in chemistry. At the onset of the 20th century, the fact that biaryls could be optically active even if lacking asymmetrically substituted carbon atoms arose interest, hinting at a novel type of stereomerism. It took quite a while (and some bizarre explanations)1 until in 1922 Christie and Kenner2 first correctly recognized that the phenomenon was the consequence of a hindered rotation about the aryl-aryl single bondshence termed atropisomerism by Kuhn. Still, no particular attention was initially paid to this class of stereoisomers until enantiomerically pure biaryls, such as BINAP (1),3 were found to be excellent ligands in asymmetric catalysis and until the chiral biaryl unit was recognized as the decisive structural element of many natural products (Figure 1).4,5 With the modern screening techniques and the bioassayguided search for novel compounds, the number of isolated axially chiral natural biaryls is steadily increasing.4 This class of secondary metabolites is characterized by a broad structural diversity, reaching from relatively simple molecules like the C2-symmetric biphenyl 2, which solely contains the element of axial chirality,6 to more complex compounds, like, e.g., the dimeric naphthylisoquinoline alkaloids michellamine A [(P,P)-3] and its axial epimer (i.e., its atropodiastereomer), michellamine B [(P,M)-3],7,8 which possess even three biaryl axes, of which the two outer ones are stereogenic, while * To whom correspondence should be addressed.

Gerhard Bringmann was born in 1951 and studied chemistry in Gie en and Münster, Germany. After his Ph.D. with Prof. B. Franck in 1978 and postdoctoral studies with Prof. Sir D. H. R. Barton in Gif-sur-Yvette (France), he passed his habilitation at the University of Münster in 1984. In 1986, he received offers for full professorships of Organic Chemistry at the Universities of Vienna and Würzburg, of which he accepted the latter in 1987. In 1998, he was offered the position of director at the Leibniz Institute of Plant Biochemistry in Halle, which he declined. His research interests focus on the field of analytical, synthetic, and computational natural product chemistry, i.e., on axially chiral biaryls. He received several prizes and awards, among them the Otto-Klung Award in chemistry (1988), the Prize for Good Teaching of the Free State of Bavaria (1999), the Adolf-Windaus Medal (2006), the Honorary Doctorate of the University of Kinshasa (2006), the Paul-J.-Scheuer Award (2007), and the Honorary Guest Professorship of Peking University (2008).

TL;DR: Cabozantinib (140 mg per day) achieved a statistically significant improvement of PFS in patients with progressive metastatic MTC and represents an important new treatment option for patients with this rare disease.
Abstract: Purpose Cabozantinib, a tyrosine kinase inhibitor (TKI) of hepatocyte growth factor receptor (MET), vascular endothelial growth factor receptor 2, and rearranged during transfection (RET), demonstrated clinical activity in patients with medullary thyroid cancer (MTC) in phase I. Patients and Methods We conducted a double-blind, phase III trial comparing cabozantinib with placebo in 330 patients with documented radiographic progression of metastatic MTC. Patients were randomly assigned (2:1) to cabozantinib (140 mg per day) or placebo. The primary end point was progression-free survival (PFS). Additional outcome measures included tumor response rate, overall survival, and safety. Results The estimated median PFS was 11.2 months for cabozantinib versus 4.0 months for placebo (hazard ratio, 0.28; 95% CI, 0.19 to 0.40; P < .001). Prolonged PFS with cabozantinib was observed across all subgroups including by age, prior TKI treatment, and RET mutation status (hereditary or sporadic). Response rate was 28% for c...

TL;DR: In this paper, the role of life stress experience in modifying 5-HTT function in the brain was discussed and integration of these findings suggests that the impact of the 5HTT gene on behavior is much broader than is commonly appreciated and may have a role in social cognition.
Abstract: The gene encoding the serotonin transporter (5-HTT) contains a regulatory variation that has been associated with anxiety-related traits and susceptibility for depression. Here we highlight recent discoveries related to allelic variation of 5-HTT function with respect to emotion regulation and social behavior, drawing from an interdisciplinary perspective of behavioral genetics and cognitive neuroscience. Following a reductionistic path that leads from gene-behavior association studies to neuroimaging and epigenetic studies, we compare two models of 5-HTT-dependent modulation of brain activity and discuss the role of life stress experience in modifying 5-HTT function in the brain. Integration of these findings suggests that the impact of the 5-HTT gene on behavior is much broader than is commonly appreciated and may have a role in social cognition.
