Chemokine Levels in the Penile Coronal Sulcus Correlate with HIV-1 Acquisition and Are Reduced by Male Circumcision in Rakai, Uganda

J. L. Prodger, R. H. Gray, B. Shannon, K. Shahabi, X. Kong, K. Grabowski, G. Kigozi, F. Nalugoda, D. Serwadda, M. J. Wawer, S. J. Reynolds, C. M. Liu, A. A. R. Tobian, R. Kaul , PLoS pathogens , DOI: 10.1371/journal.ppat.1006025
Individual susceptibility to HIV is heterogeneous, but the biological mechanisms explaining differences are incompletely understood. We hypothesized that penile inflammation may increase HIV susceptibility in men by recruiting permissive CD4 T cells, and that male circumcision may decrease HIV susceptibility in part by reducing genital inflammation. We used multi-array technology...

Infrequent mismatch repair protein loss in gallbladder cancer patients in Japan

H. Yoshida, K. Shimada, N. Hiraoka , Virchows Archiv , DOI: 10.1007/s00428-016-2043-5
Gallbladder cancer (GBC) represents a rare malignancy worldwide. Its prognosis is poor, and in Chile and East Asia, including Japan and China, a relative increase in the incidence of GBC has been observed [1]. The development of new therapies is required for the treatment of this aggressive and intractable type...

Generation of metastatic melanoma specific antibodies by affinity purification

B. Schütz, A. Koppensteiner, D. Schörghofer, K. Kinslechner, G. Timelthaler, R. Eferl, M. Hengstschläger, A. Missbichler, H. Hundsberger & M. Mikula , Scientific Reports , doi:10.1038/srep37253
Melanoma is the most aggressive type of skin cancer and one of the most frequent tumours in young adults. Identification of primary tumours prone to develop metastasis is of paramount importance for further patient stratification. However, till today, no markers exist that are routinely used to predict melanoma progression. To...

Activity-Based Protein Profiling Shows Heterogeneous Signaling Adaptations to BRAF Inhibition

R. Sharma, I. Fedorenko, P. T. Spence, V. K. Sondak, K. S. M. Smalley, J. M. Koomen , Journal of Proteome Research , DOI: 10.1021/acs.jproteome.6b00613
Patients with BRAF V600E mutant melanoma are typically treated with targeted BRAF kinase inhibitors, such as vemurafenib and dabrafenib. Although these drugs are initially effective, they are not curative. Most of the focus to date has been upon genetic mechanisms of acquired resistance; therefore, we must better understand the global...

A systems toxicology approach for comparative assessment: Biological impact of an aerosol from a candidate modified-risk tobacco product and cigarette smoke on human...

A. R. Iskandar, C. Mathis, W. K. Schlage, S. Frentzel, P. Leroy, Y. Xiang, A. Sewer, S. Majeed, L. Ortega-Torres, S. Johne, E. Guedj, K. Trivedi, G. Kratzer, C. Merg, A. Elamin, F. Martin, N. V. Ivanov, M. C. Peitsch, J. Hoeng , Toxicology in Vitro , DOI: 10.1016/j.tiv.2016.11.009
This study reports a comparative assessment of the biological impact of a heated tobacco aerosol from the tobacco heating system (THS) 2.2 and smoke from a combustible 3R4F cigarette. Human organotypic bronchial epithelial cultures were exposed to an aerosol from THS2.2 (a candidate modified-risk tobacco product) or 3R4F smoke at...
