A novel regulatory role of TRAPPC9 in L‐plastin‐mediated osteoclast actin ring formation
We investigated the potential regulatory role of TRAPPC9 and LPL‐mediated OC cytoskeleton reorganization and actin ring formation. Abstract Trafficking protein particle complex 9 (TRAPPC9) is a major subunit of the TRAPPII complex. TRAPPC9 has been reported to bind nuclear factor κB kinase subunit β (IKKβ) and NF‐kB‐inducing kinase (NIK) where it plays a role in the canonical and noncanonical of nuclear factor‐κB (NF‐kB) signaling pathways, receptively. The role of TRAPPC9 in protein trafficking...

Interleukin‐1 beta induces autophagy of mouse preimplantation embryos and improves blastocyst quality
Exogenous interleukin‐1β can effectively induce autophagy of mouse embryos at stages of 2 to 8 cell and blastocyst, which also help to improve blastocyst quality. Abstract Autophagy is one of the basic cellular mechanism during preimplantation development of mammalian embryos, and it plays crucial role in several physiological processes. It is induced by interleukin (IL)‐1β in mammalian cells. Our present study shows that IL‐1β is important for autophagy activation in embryo development. Our...

Myelopreservation with the CDK4/6 inhibitor trilaciclib in patients with small cell lung cancer receiving 1st-line chemotherapy: a Phase 1b/randomized Phase 2 trial
AbstractBackgroundChemotherapy-induced damage of hematopoietic stem and progenitor cells (HSPC) causes multi-lineage myelosuppression. Trilaciclib is an intravenous CDK4/6 inhibitor in development to proactively preserve HSPC and immune system function during chemotherapy (myelopreservation). Preclinically, trilaciclib transiently maintains HSPC in G1 arrest and protects them from chemotherapy damage, leading to faster hematopoietic recovery and enhanced anti-tumor immunity.Patients and methodsThis...

Targeting Degradation of the Transcription Factor C/EBPβ Reduces Lung Fibrosis by Restoring Activity of the Ubiquitin-Editing Enzyme A20 in Macrophages
Dysregulation of the ubiquitin-editing enzyme A20 contributes to the development of several human inflammatory diseases. Liu et al. demonstrate that suppression of A20 enzymatic activity in alveolar macrophages promotes lung fibrosis by reducing transcriptional factor C/EBPβ degradation and enhancing targeted gene expression, which directs the profibrotic phenotype of macrophages.

Differential Activation of the Transcription Factor IRF1 Underlies the Distinct Immune Responses Elicited by Type I and III Interferons
Type I IFNs, but not type III IFNs (IFNλ), promote inflammation at the site of infection. Forero et al. find that differential expression of proinflammatory genes results from selective induction of the transcription factor IRF1 by type I IFNs. Type III IFNs induce a tissue repair program, suggesting a division of labor that spans proinflammatory and tissue repair functions to promote protective immunity.

Oncolytic Viruses Engineered to Enforce Leptin Expression, Reprogram Tumor-Infiltrating T Cell Metabolism, and Promote Tumor Clearance
Metabolic insufficiency is a major barrier for antitumor immunity. Rivadeneira et al. demonstrate that engineering an oncolytic virus to express a metabolic modulator, in this case the adipokine leptin, improves T cell metabolic function in the tumor microenvironment, allowing a superior antitumor response compared to a control oncolytic.

Noval Rivas et al. demonstrate that a murine model of KD vasculitis is dependent on intestinal barrier dysfunction leading to secretory IgA leakage and IgA-C3 immune complex deposition in cardiovascular lesions.

Task-evoked reconfiguration of the fronto-parietal network is associated with cognitive performance in brain tumor patients
Abstract In healthy participants, the strength of task-evoked network reconfigurations is associated with cognitive performance across several cognitive domains. It is, however, unclear whether the capacity for network reconfiguration also plays a role in cognitive deficits in brain tumor patients. In the current study, we examined whether the level of reconfiguration of the fronto-parietal (‘FPN’) and default mode network (‘DMN’) during task execution is correlated with cognitive...

Primary non-complicated midline ventral hernia: is laparoscopic IPOM still a reasonable approach?
Abstract Purpose Ventral hernia repair has become a common procedure, but the way in which it is performed still depends on surgeon’s skill, experience, and habit. The initial open approach is faced with extensive dissection and a high risk of infection and prolonged hospital stay. To tackle these problems, minimally invasive procedures are gaining interest.

Prevalence and Clinical Significance of Biliary Intraepithelial Neoplasia (BilIN) in Cholangiocarcinoma
Abstract Biliary intraepithelial neoplasia (BilIN) is a noninvasive precursor lesion which progresses to cholangiocarcinoma (CC). BilIN is often found synchronously adjacent to the tumor or at the surgical resection margin of resection CC. However, irrespective of its location, its prognostic significance on outcome after CC resection is unknown. The aim of this study was to elucidate the prevalence of BilIN in CC and to determine if the presence of BilIN has a prognostic or predictive...

We present the functional characterization of a pseudogene associated recurrent gene fusion in prostate cancer. The fusion gene KLK4-KLKP1 is formed by the fusion of the protein coding gene KLK4 with the noncoding pseudogene KLKP1. Screening of a cohort of 659 patients (380 Caucasian American; 250 African American, and 29 patients from other races) revealed that the KLK4-KLKP1 is expressed in about 32% of prostate cancer patients. Correlative analysis with other ETS gene fusions and SPINK1 revealed...

Targeting c-MYC through Interference with NAMPT and SIRT1 and Their Association to Oncogenic Drivers in Murine Serrated Intestinal Tumorigenesis.
In conclusion we show that the c-MYC-NAMPT-DBC1-SIRT1 positive feedback loop contributes to murine serrated tumor progression. Targeting the feedback loop exerted a unique, dual therapeutic effect of oncoprotein inhibition and tumor suppressor activation. It may therefore represent a promissing target for serrated colorectal cancer, and presumably for other cancer types with deregulated c-MYC.
