Alr sensitizes Hcc cells to the chemotherapeutical drug by its inhibition of the Akt/snail signaling pathway, consequentlyinactivating Abc transporter expression. Yuan-yuan Guo, Yuan Wu, Xiao-wei Jia and Wei An 2017 97: 1400-1411; advance online publication, August 21, 2017; 10.1038/labinvest.2017.72 Abstract | Full Text | | | | Upregulation of the actin cytoskeleton via myocardin leads to increased expression of type 1 collagen Hepatic stellate cells become activated and transform into myofibroblasts during liver fibrosis. Myocardin promotes this process through upregulation of actin isoforms and the actin cytoskeleton. This in turn stimulates actin dynamics and concomitant actin functions as well as fibrogenesis and the liver wound healing response. Zengdun Shi and Don C Rockey 2017 97: 1412-1426; advance online publication, October 16, 2017; 10.1038/labinvest.2017.96 Abstract | Full Text | | | | GENITOURINARY AND REPRODUCTIVE SYSTEMS | Deletion of Pkd1 in renal stromal cells causes defects in the renal stromal compartment and progressive cystogenesis in the kidney This study found that disruption of pkd1 (polycystin-1) from renal stromal cells causes defects in the renal stromal compartment, including reduced extracellular matrix and vascularrarefaction. Furthermore, renal epithelia exhibited increased proliferation and apoptosis associated with progressive cystogenesis in modelling of adulthood human autosomal dominant polycystic kidney disease. Xuguang Nie and Lois J Arend 2017 97: 1427-1438; advance online publication, September 11, 2017; 10.1038/labinvest.2017.97 Abstract | Full Text | | | | Vascular endothelial growth factor-C ameliorates renal interstitial fibrosis through lymphangiogenesis in mouse unilateral ureteral obstruction In this study, the authors investigated the effect of vascular endothelial growth factor-c (vegf-c) on lymphangiogenesis, inflammation and fibrosis in mouse kidneys using a unilateral ureteral obstruction model of interstitial inflammation and fibrosis. Continuous Vegf-c administration induceslymphangiogenesis and attenuates renal fibrosis. Enhancement of the Vegf-c/vegfr-3 signaling pathway might be a therapeutic option for renal fibrotic diseases. Shoko Hasegawa, Toshiaki Nakano, Kumiko Torisu, Akihiro Tsuchimoto, Masahiro Eriguchi, Naoki Haruyama, Kosuke Masutani, Kazuhiko Tsuruya and Takanari Kitazono 2017 97: 1439-1452; advance online publication, October 30, 2017; 10.1038/labinvest.2017.77 Abstract | Full Text | | | | Correlation between E-cadherin interactions, survivin expression, and apoptosis in MDCK and ts-Src MDCK cell culture models In a soft extracellular matrix environment, MDCK cells resemble adult tissue: they become fully differentiated, survivin is down-regulated, E-cadherin trans-interactions are well-developed, and the cells are susceptible to stress-induced apoptosis. In MDCK cells stably transfected with temperature sensitive viral Src, survivin is up-regulated and E-cadherin is relocated to the cytoplasm. Reactive oxygen species induces survivin down-regulation and apoptosis. The antioxidant N-acetylcysteine rescues the cells by returning E-cadherin to membranes. Janne Capra and Sinikka Eskelinen 2017 97: 1453-1470; advance online publication, September 11, 2017; 10.1038/labinvest.2017.89 Abstract | Full Text | | | | BLOOD, LYMPHATICS, IMMUNE SYSTEM AND STEM CELLS | Ligand-mediated cytoplasmic retention of the Ah receptor inhibits macrophage-mediated acute inflammatory responses Two in vivo macrophage-driven acute mouse inflammation models were utilized to test whether the selective Ah receptor modulator SGA360 would reduce inflammation. Exposure to SGA360 is capable of significantly inhibiting lipopolysaccharide-mediated endotoxic shock and joint edema in a monosodium urate crystal gout models in an Ah receptor-dependent fashion. Gulsum E Muku, Tejas S Lahoti, Iain A Murray, Michael A Podolsky, Kayla J Smith, Troy D Hubbard, Guray Kuzu, Krishne Gowda, Shantu G Amin and Gary H Perdew 2017 97: 1471-1487; advance online publication, September 11, 2017; 10.1038/labinvest.2017.92 Abstract | Full Text | | | | ENDOCRINE, VISUAL AND AUDITORY SYSTEMS | Expression, function, and regulation of the embryonic transcription factor TBX1 in parathyroid tumors The embryonic transcription factor TBX1, the candidate gene for 22q11.2-DiGeorge syndrome, which includes congenital hypoparathyroidism, is expressed in a subset of adult normal parathyroid glands and variably lost in parathyroid tumors as well as in fetal parathyroid glands. The authors show that TBX1 silencing is associated with cell cycle arrest and reduction of WNT5A; parathyroid tumors display cell heterogeneity and embryonic features. Chiara Verdelli, Laura Avagliano, Vito Guarnieri, Filomena Cetani, Stefano Ferrero, Leonardo Vicentini, Edoardo Beretta, Alfredo Scillitani, Pasquale Creo, Gaetano Pietro Bulfamante, Valentina Vaira and Sabrina Corbetta 2017 97: 1488-1499; advance online publication, September 18, 2017; 10.1038/labinvest.2017.88 Abstract | Full Text | | | | MODELS AND TECHNIQUES | A simple method based on Sanger sequencing and MS Word wildcard searching to identify Cas9-induced frameshift mutations The authors developed a simple strategy to predict Crispr/cas9 induced indels, by analysis of the sequencing paragraph with wildcard searching (sws). This strategy reliably predicts if indels exist in each allele of the diploid genome and their exact numbers, which significantly facilitates the isolation of single clones harboring biallelic frame-shift alleles. Hui Jie, Zhuoling Li, Ping Wang, Linjie Zhao, Qian Zhang, Xiaomin Yao, Xiangrong Song, Yinglan Zhao and Shaohua Yao 2017 97: 1500-1507; advance online publication, August 21, 2017; 10.1038/labinvest.2017.83 Abstract | Full Text | | Technical Reports | Top | | Whole tumor section quantitative image analysis maximizes between-pathologists’ reproducibility for clinical immunohistochemistry-based biomarkers It is challenging for pathologists' quantitative scoring of immunohistochemistry-stained slides to meet high between-pathologist reproducibility. Technologies such as computational image analysis are available; however, its adoption is limited clinically. To increase image analysis's value proposition, the authors instituted a novel whole tumor section annotation approach across multiple modalities and biomarkers. This approach showed superiority compared to other modalities.

Technologies such as computational image analysis are available; however, its adoption is limited clinically. To increase image analysis's value proposition, the authors instituted a novel whole tumor section annotation approach across multiple modalities and biomarkers.

Yaping N Tu, Wei Lue Tong, Timothy J Fawcett and George Blanck 2017 97: 1516-1520; advance online publication, August 14, 2017; 10.1038/labinvest.2017.80 Abstract | Full Text | | | | High concordance of a closed-system, RT-qPCR breast cancer assay for HER2 mRNA, compared to clinically determined immunohistochemistry, fluorescence in situ hybridization, and quantitative immunofluorescence Both immunohistochemistry and fluorescence in situ hybridization can be used to assess HER2 status, but these tests are time-consuming, expensive and they are sometimes equivocal. In this pilot study, the authors describe an inexpensive, rapid, closed system method for quantitative reverse transcription polymerase chain reaction assessment of HER2 that is highly concordant with current methods.
