Domain Adaptation for Semantic Segmentation with Maximum Squares Loss [article]

Minghao Chen, Hongyang Xue, Deng Cai
2019 arXiv   pre-print
Deep neural networks for semantic segmentation always require a large number of samples with pixel-level labels, which becomes the major difficulty in their real-world applications. To reduce the labeling cost, unsupervised domain adaptation (UDA) approaches are proposed to transfer knowledge from labeled synthesized datasets to unlabeled real-world datasets. Recently, some semi-supervised learning methods have been applied to UDA and achieved state-of-the-art performance. One of the most

However, when applying the entropy minimization to UDA for semantic segmentation, the gradient of the entropy is biased towards samples that are easy to transfer. To balance the gradient of well-classified target samples, we propose the maximum squares loss. Our maximum squares loss prevents the training process being dominated by easy-to-transfer samples in the target domain. Besides, we introduce the image-wise weighting ratio to alleviate the class imbalance in the unlabeled target domain. Both synthetic-to-real and cross-city adaptation experiments demonstrate the effectiveness of our proposed approach. The code is released at https://github. com/ZJULearning/MaxSquareLoss.

Jiwei Huang, Wen Cai, Biao Cai, Wen Kong, Wei Zhai, Jin Zhang, Yonghui Chen, Shiqing Chen, Yuezong Bai, Yiran Huang, Wei Xue
2021 Frontiers in Oncology  
Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal cell carcinoma (RCC). The genomic landscape in Chinese ccRCC needs to be elucidated. Herein, we investigated the molecular features of Chinese ccRCC patients. Genomic profiling of DNA was performed through next-generation sequencing (NGS) in Chinese patients with ccRCC between January 2017 and March 2020. Clinical information including age, gender, and tumor histology was collected. Immunohistochemistry (IHC) staining

A total of 880 Chinese ccRCC patients who have undergone NGS were included in this study. The most common somatic alterations were detected in VHL (59.7%), PBRM1 (18.0%), SETD2 (12.2%), BAP1 (10.2%), and TP53 (9.4%). Compared with The Cancer Genome Atlas (TCGA) database, a higher mutation frequency of VHL (59.7% vs. 50.0%, p < 0.001) and TP53 (9.4% vs. 3.5%, p < 0.001) and a lower mutation frequency of PBRM1 (18.0% vs. 31.0%, p < 0.001) were found in the Chinese cohort. Of the 460 patients who were evaluated for PD-L1 expression, 139 (30.2%) had positive PD-L1 expression. The median tumor mutational burden (TMB) value was 4.5 muts/Mb (range, 0–46.0). Five (0.7%) patients were identified as microsatellite instability-high (MSI-H). Furthermore, 52 (5.9%) patients were identified to carry pathogenic or likely pathogenic germline mutations in 22 cancer predisposition genes. This is the first large-scale comprehensive genomic analysis for Chinese ccRCC patients, and these results might provide a better understanding of molecular features in Chinese ccRCC patients, which can lead to an improvement in the personalized treatment for these patients.

Screening of key genes related to the prognosis of mouse sepsis

Muhu Chen, Xue Chen, Yingchun Hu, Xianfu Cai
2020 Bioscience Reports  
Sepsis is a common clinical disease with high mortality, and patients with sepsis have varied prognoses. Researchers need to explore the underlying mechanisms that determine the prognosis of sepsis. Hence, a mouse model was used to evaluate new potential prognostic markers of sepsis. Mice were randomly divided into low-dose group (n = 3, lipopolysaccharides [LPS], 20mg/kg) and high-dose group (n = 3; LPS, 40mg/kg). Total RNA was extracted from the peripheral blood of mice, and samples were then

When complete data were normalized, the high-dose group and low-dose group were screened for differentially expressed genes (DEGs, log2FC ≥ 1 and q value ≤ 0.05). DEGs were analyzed by gene ontology enrichment, and potential core genes were screened using protein–protein interaction network (PPI) and weighted gene co-expression network analysis (WGCNA). Moreover, the survival data in GSE65682 was used to observe the correlation between core genes and prognosis. A total of 967 DEGs were identified in the low-dose group, of which 390 were upregulated and 577 were downregulated. These genes were mainly enriched in white blood cell activation, lymphocyte activation, immune system response, etc. LCK, ZAP70, ITK, CD247, and DOCK2 were found at the core of PPI network, while WGCNA found that IFI35, ITGB3, and MED25 may be potential core genes. It was demonstrated that CD247, DOCK2, IFI35, ITK, and LCK core genes were positively correlated with prognosis based on GSE65682. CD247, DOCK2, IFI35, ITK, LCK, and MED25 might be important targets affecting the prognosis of sepsis.

Yu-Peng Wu, Zhi-Bin Ke, Wen-Cai Zheng, Ye-Hui Chen, Jun-Ming Zhu, Fei Lin, Xiao-Dong Li, Shao-Hao Chen, Hai Cai, Qing-Shui Zheng, Yong Wei, Xue-Yi Xue (+1 others)
2021 Cell Death and Disease  
AbstractExpression of kinesin family member 18B (KIF18B), an ATPase with key roles in cell division, is deregulated in many cancers, but its involvement in prostate cancer (PCa) is unclear. Here, we investigated the expression and function of KIF18B in human PCa specimens and cell lines using bioinformatics analyses, immunohistochemical and immunofluorescence microscopy, and RT-qPCR and western blot analyses. KIF18B was overexpressed in PCa specimens compared with paracancerous tissues and was

In vitro, KIF18B knockdown in PCa cell lines promoted cell proliferation, migration, and invasion, and inhibited cell apoptosis, while KIF18B overexpression had the opposite effects. In a mouse xenograft model, KIF18B overexpression accelerated and promoted the growth of PCa tumors. Bioinformatics analysis of control and KIF18B-overexpressing PCa cells showed that genes involved in the PI3K–AKT–mTOR signaling pathway were significantly enriched among the differentially expressed genes. Consistent with this observation, we found that KIF18B overexpression activates the PI3K–AKT–mTOR signaling pathway in PCa cells both in vitro and in vivo. Collectively, our results suggest that KIF18B plays a crucial role in PCa via activation of the PI3K–AKT–mTOR signaling pathway, and raise the possibility that KIF18B could have utility as a novel biomarker for PCa.

2015 PLoS ONE  
MicroRNAs (miRs) play important roles in modulating gene expression during the processes of tumorigenesis and tumor development. Previous studies have found that miR-145 is down-regulated in the stomach neoplasm and is related to tumor migration and invasion. However, both the molecular mechanism and function of miR-145 in gastric cancer remain unclear. The present study is the first demonstration of the significant down-regulation of miR-145 expression in infiltrative gastric cancer compared

Furthermore, we demonstrated that miR-145 directly targets FSCN1 and suppresses cell migration and invasion in gastric cancer. Knocking down the expression of FSCN1 led to the suppression of migration and invasion in gastric cancer cells, and re-expressing FSCN1 in miR-145-overexpressing cells reversed their migration and invasion defects. Thus, we concluded that miR-145 regulates cell migration and invasion in gastric cancer primarily by directly targeting FSCN1.

Kaplan-Meier curves and multivariable Cox proportion hazard model were performed to associate Connexin 43 expression with postoperative biochemical recurrence-free survival (BFS). Connexin 43 expression was significantly reduced or lost in tumor tissues compared to that of BPHs (39.1% vs. 96.7%, P<0.001). Reduced Connexin 43 expression was associated with high levels of preoperative PSA, high Gleason score, advanced pT stage, positive surgical margin, extracapsular extension, and seminal vesicle invasion (P < 0.05, for all). Kaplan-Meier curves showed that reduced Connexin 43 expression was associated with shortened postoperative BFS (P < 0.001). Multivariate analysis showed that reduced Connexin 43 expression, high Gleason score and advanced pT stage were independent predictors for BFS of patients (P < 0.05). Connexin 43 expression was significantly reduced or lost in prostate cancer tissues, which was associated with advanced clinicopathological features and poor BFS of patients after radical prostatectomy.

To verify that the trabecular meshwork (TM) in the wall of the eyeball consists of smooth muscle fibers instead of collagen fibers or endothelial cells. Eighteen fresh eyeballs from 3 rabbits, 3 SD rats and 3 mice were sectioned along the sagittal plane and sliced after paraffin embedding for HE staining, VG staining, Masson staining, α-SMA immunohistochemistry or CD31 immunohistochemistry. These slices were observed under microscope and the structure of the TM was compared with those of
more » ... collagen fibers, ciliary muscles and endothelial cells. HE staining of the eyeball slices from the 3 animal species resulted in purplish red staining of the TM, which was highly consistent with ciliary muscle fibers. The cell?like structures on the surface of the TM were not clearly outlined, with flat nuclei showing a dark purple staining; these structures did not show obvious boundaries from the TM. Ciliary muscle fibers, which were smooth muscle cells in nature, were aligned in bundles in various directions. The longitudinally sectioned cells were flat and contained purplish cytoplasm and highly flattened nuclei. Scleral collagen fibers were stained dark red with a few fibroblasts sandwiched among them. The long axis of the fibroblasts was in parallel with that of the collagen fibers. The outline of the fibroblast was not clear and the nucleus was flat in dark blue. The vascular endothelial cells presented with different morphologies and contained light purplish cytoplasm and dark nuclei, protruding into the vascular cavity. VG staining of the TM revealed a pale red filamentous structure, and the collagen fibers were stained bright red. Masson staining of the TM showed a reticular structure consisting mainly of dark red fibers intermingled with thin green fibers. Scleral collagen fibers presented with a cord?like green wavy structure. The endothelial cells were green and flat, while the ciliary smooth muscle fibers were purple. In immunohistochemistry for α?SMA, the TM and the ciliary smooth muscle fibers showed a strong positivity in the cytoplasm, while the scleral collagen fibers and vascular endothelial cells showed negative staining; immunohistochemistry for CD31 showed no obvious positive staining in the TM, collagen fibers or ciliary smooth muscle cells from all the animals in spite of slight differences among them. The TM consists mainly of smooth muscle fibers with a thin layer of peripheral endomysium without endothelial cells.
