A chemical probe for BAG1 targets androgen receptor-positive prostate cancer through oxidative stress signaling pathway
BAG1 is a family of polypeptides with a conserved C-terminal BAG domain that functions as a nucleotide exchange factor for the molecular chaperone HSP70. BAG1 proteins also control several signaling processes including proteostasis, apoptosis and transcription. The largest isoform, BAG1L, controls the activity of the androgen receptor (AR) and is upregulated in prostate cancer. Here, we show that BAG1L regulates AR dynamics in the nucleus and its ablation attenuates AR target gene expression especially those involved in oxidative stress and metabolism. We show that a small molecule, A4B17 that targets the BAG domain downregulates AR target genes similar to a complete BAG1L knockout and upregulates the expression of oxidative stress-induced genes involved in cell death. Furthermore, A4B17 outperformed the clinically approved antagonist enzalutamide in inhibiting cell proliferation and prostate tumor development in a mouse xenograft model. BAG1 inhibitors therefore offer unique opportunities for antagonizing AR action and prostate cancer growth
Learning from Trade Through Innovation: Causal Link Between Imports, Exports and Innovation in Spanish Microdata
Genetic association study of QT interval highlights role for calcium signaling pathways in myocardial repolarization.
The QT interval, an electrocardiographic measure reflecting myocardial repolarization, is a heritable trait. QT prolongation is a risk factor for ventricular arrhythmias and sudden cardiac death (SCD) and could indicate the presence of the potentially lethal mendelian long-QT syndrome (LQTS). Using a genome-wide association and replication study in up to 100,000 individuals, we identified 35 common variant loci associated with QT interval that collectively explain ∼8-10% of QT-interval variation and highlight the importance of calcium regulation in myocardial repolarization. Rare variant analysis of 6 new QT interval-associated loci in 298 unrelated probands with LQTS identified coding variants not found in controls but of uncertain causality and therefore requiring validation. Several newly identified loci encode proteins that physically interact with other recognized repolarization proteins. Our integration of common variant association, expression and orthogonal protein-protein interaction screens provides new insights into cardiac electrophysiology and identifies new candidate genes for ventricular arrhythmias, LQTS and SCD
International cancer of the pancreas screening (CAPS) consortium summit on the management of patients with increased risk for familial pancreatic cancer
Background Screening individuals at increased risk for
pancreatic cancer (PC) detects early, potentially curable,
pancreatic neoplasia.
Objective To develop consortium statements on
screening, surveillance and management of high-risk
individuals with an inherited predisposition to PC.
Methods A 49-expert multidisciplinary international
consortium met to discuss pancreatic screening and vote
on statements. Consensus was considered reached if
≥75% agreed or disagreed.
Results There was excellent agreement that, to be
successful, a screening programme should detect and
treat T1N0M0 margin-negative PC and high-grade
dysplastic precursor lesions (pancreatic intraepithelial
neoplasia and intraductal papillary mucinous neoplasm). It
was agreed that the following were candidates for
screening: first-degree relatives (FDRs) of patients with
PC from a familial PC kindred with at least two affected
FDRs; patients with Peutz–Jeghers syndrome; and p16,
BRCA2 and hereditary non-polyposis colorectal cancer
(HNPCC) mutation carriers with ≥1 affected FDR.
Consensus was not reached for the age to initiate
screening or stop surveillance. It was agreed that initial
screening should include endoscopic ultrasonography
(EUS) and/or MRI/magnetic resonance
cholangiopancreatography not CT or endoscopic
retrograde cholangiopancreatography. There was no
consensus on the need for EUS fine-needle aspiration to
evaluate cysts. There was disagreement on optimal
screening modalities and intervals for follow-up imaging.
When surgery is recommended it should be performed at
a high-volume centre. There was great disagreement as
to which screeni
Surveillance for pancreatic cancer in high-risk individuals
Background: Surveillance of individuals at high risk of pancreatic ductal adenocarcinoma (PDAC) and its
precursors might lead to better outcomes. The aim of this study was to determine the prevalence
and outcomes of PDAC and high-risk neoplastic precursor lesions among such patients participating
in surveillance programmes.
Methods: A multicentre study was conducted through the International CAncer of the Pancreas Screening (CAPS) Consortium Registry to identify high-risk individuals who had undergone pancreatic resection or progressed to advanced PDAC while under surveillance. High-risk neoplastic precursor lesions
were defined as: pancreatic intraepithelial neoplasia (PanIN) 3, intraductal papillary mucinous neoplasia
(IPMN) with high-grade dysplasia, and pancreatic neuroendocrine tumours at least 2 cm in diameter.
Results: Of 76 high-risk individuals identified in 11 surveillance programmes, 71 had undergone surgery
and five had been diagnosed with inoperable PDAC. Of the 71 patients who underwent resection, 32
(45 per cent) had PDAC or a high-risk precursor (19 PDAC, 4 main-duct IPMN, 4 branch-duct IPMN,
5 PanIN-3); the other 39 patients had lesions thought to be associated with a lower risk of neoplastic
progression. Age at least 65 years, female sex, carriage of a gene mutation and location of a lesion in the
head/uncinate region were associated with high-risk precursor lesions or PDAC. The survival of high-risk
individuals with low-risk neoplastic lesions did not differ from that in those with high-risk precursor
lesions. Survival was worse among patients with PDAC. There was no surgery-related mortality.
Conclusion: A high proportion of high-risk individuals who had surgical resection for screening- or
surveillance-detected pancreatic lesions had a high-risk neoplastic precursor lesion or PDAC
Envenomations by Bothrops and Crotalus Snakes Induce the Release of Mitochondrial Alarmins
Skeletal muscle necrosis is a common manifestation of viperid snakebite envenomations. Venoms from snakes of the genus Bothrops, such as that of B. asper, induce muscle tissue damage at the site of venom injection, provoking severe local pathology which often results in permanent sequelae. In contrast, the venom of the South American rattlesnake Crotalus durissus terrificus, induces a clinical picture of systemic myotoxicity, i.e., rhabdomyolysis, together with neurotoxicity. It is known that molecules released from damaged muscle might act as ‘danger’ signals. These are known as ‘alarmins’, and contribute to the inflammatory reaction by activating the innate immune system. Here we show that the venoms of B. asper and C. d. terrificus release the mitochondrial markers mtDNA (from the matrix) and cytochrome c (Cyt c) from the intermembrane space, from ex vivo mouse tibialis anterior muscles. Cyt c was released to a similar extent by the two venoms whereas B. asper venom induced the release of higher amounts of mtDNA, thus reflecting hitherto some differences in their pathological action on muscle mitochondria. At variance, injection of these venoms in mice resulted in a different time-course of mtDNA release, with B. asper venom inducing an early onset increment in plasma levels and C. d. terrificus venom provoking a delayed release. We suggest that the release of mitochondrial ‘alarmins’ might contribute to the local and systemic inflammatory events characteristic of snakebite envenomations
Clinical characteristics of coronavirus disease (COVID-19) early findings from a teaching hospital in Pavia, North Italy, 21 to 28 February 2020
We describe clinical characteristics, treatments and outcomes of 44 Caucasian patients with coronavirus disease (COVID-19) at a single hospital in Pavia, Italy, from 21\u201328 February 2020, at the beginning of the outbreak in Europe. Seventeen patients developed severe disease, two died. After a median of 6 days, 14 patients were discharged from hospital. Predictors of lower odds of discharge were age>65 years, antiviral treatment and for severe disease, lactate dehydrogenase >300 mg/dL
