Multiple Imputation Inference with Integer-Valued Point Estimates

Bo Liu & Jerome P. Reiter
We consider settings where an analyst of multiply imputed data desires an integer-valued point estimate and an associated interval estimate, for example, a count of the number of individuals with certain characteristics in a population. Even when the point estimate in each completed dataset is an integer, the multiple imputation point estimator, that is, the average of these completed-data estimators, is not guaranteed to be an integer. One natural approach is to round the standard...

Inference on moderation effect with third-variable effect analysis – application to explore the trend of racial disparity in oncotype dx test for breast cancer treatment

Qingzhao Yu, Lu Zhang, Xiaocheng Wu & Bin Li
Third variable effect refers to the effect from a third variable that explains an observed relationship between an exposure and an outcome. Depending on whether there is causal relationship, typically, a third variable takes the format of a mediator or a confounder. A moderation effect is a special case of the third-variable effect, where the moderator and other variables have an interactive effect on the outcome. In this paper, we extend the R package ‘mma’...

Plant litter influences the temporal stability of plant community biomass in an alpine meadow by altering the stability and asynchrony of plant functional groups

Zhouwen Ma, Yifeng Zeng, Jing Wu, Qingping Zhou & Fujiang Hou
​​​The stability of a plant community is defined as its ability to resist and be resilient to changes. Plant community stability can be driven by a range of external perturbations as well as by plant community traits. Plant litter traits (species or mass) are widely recognized drivers for plant community composition and diversity changes in grasslands. Yet, the effects of litter traits on the temporal stability of plant communities in natural grasslands are largely unknown....

Tumour suppressor TET2 safeguards enhancers from aberrant DNA methylation and epigenetic reprogramming in ERα-positive breast cancer cells

Ruitu Lyu, Xuguo Zhu, Yinghui Shen, Lijun Xiong, Lu Liu, Hang Liu, Feizhen Wu, Christian Argueta & Li Tan
Aberrant DNA methylation is an epigenetic hallmark of malignant tumours. The DNA methylation level is regulated by not only DNA methyltransferases (DNMTs) but also Ten-Eleven Translocation (TET) family proteins. However, the exact role of TET genes in breast cancer remains controversial. Here, we uncover that the ERα-positive breast cancer patients with high TET2 mRNA expression had better overall survival rates. Consistently, knockout of TET2 promotes the tumorigenesis of ERα-positive MCF7 breast cancer cells. Mechanistically, TET2...

YhjC is a novel transcriptional regulator required for Shigella flexneri virulence

Wanwu Li, Lingyan Jiang, Xiaoqian Liu, Rui Guo, Shuai Ma, Jingting Wang, Shuangshuang Ma, Shujie Li & Huiying Li
Shigella is an intracellular pathogen that primarily infects the human colon and causes shigellosis. Shigella virulence relies largely on the type III secretion system (T3SS) and secreted effectors. VirF, the master Shigella virulence regulator, is essential for the expression of T3SS-related genes. In this study, we found that YhjC, a LysR-type transcriptional regulator, is required for Shigella virulence through activating the transcription of virF. Pathogenicity of the yhjC mutant, including colonization in the colons of...

Therefore, this study aimed to examine the underlying roles of AGR2 and miR-199a-3p in the development of LUAD. The expression levels of miR-199a-3p and AGR2 in LUAD tissues and cells were detected via quantitative reverse transcription-polymerase chain reaction (qRT-PCR). A luciferase...

Cenozoic rifting and inversion of Beibuwan Basin and its linkage with the strike-slip movement along the Ailao Shan-Red River Shear Zone

Yanjun Cheng, Zhiping Wu, Jie Zhang, Yuqing Liu, Zhengkai Wang & Yining Dai
The Cenozoic Beibuwan Basin is located along the eastern margin of the Ailao Shan Red River Shear Zone (ASRRSZ). The rifting and inversion processes of this basin provide important clues to the mechanism by which extrusion tectonics drive continental rifting and inversion development. However, the rifting and inversion of this basin remain ambiguous. Here, we employ seismic data, information about the time and displacement of faulting, syn-rift fault and isopach maps to analyse the Cenozoic...

Downregulation of Smad4 expression confers chemoresistance against imatinib mesylate to chronic myeloid leukemia K562 cells

Jiangzhao Zhang, Min Zhang, Yan Liang, Min Liu & Zhiping Huang
Objective: Imatinib mesylate (IM), a tyrosine kinase inhibitor, exhibits clinically prominent effects against chronic myeloid leukemia (CML); however, a few patients have shown resistance to IM treatment, resulting in disease progression. Smad4 is a tumor inhibitor that transduces TGF-β signaling and modulates genomic stability. Previous studies have indicated that decreased Smad4 expression played a bidirectional role in chemosensitivity in many types of cancers. Therefore, this study aims to evaluate the association between IM sensitivity and...

Cell membrane-anchored anti-HIV single-chain antibodies and bifunctional inhibitors targeting the gp41 fusion protein: new strategies for HIV gene therapy

Yue Chen, Hongliang Jin, Xiaoran Tang, Li Li, Xiuzhu Geng, Yuanmei Zhu, Huihui Chong & Yuxian He
Emerging studies indicate that infusion of HIV-resistant cells could be an effective strategy to achieve a sterilizing or functional cure. We recently reported that glycosylphosphatidylinositol (GPI)-anchored nanobody or a fusion inhibitory peptide can render modified cells resistant to HIV-1 infection. In this study, we comprehensively characterized a panel of newly isolated HIV-1-neutralizing antibodies as GPI-anchored inhibitors. Fusion genes encoding the single-chain variable fragment (scFv) of 3BNC117, N6, PGT126, PGT128, 10E8, or 35O22 were constructed with...

Fungal disease temporal stability in an alpine meadow

Xiang Liu
Current unprecedented species extinction has galvanized studies to clarify how biodiversity affects diseases. However, almost all empirical studies focused on diseases at a certain time point, largely ignoring the temporal stability. Using a removal experiment that manipulates plant diversity, and a fertilization experiment in a Tibetan alpine meadow, we investigated how different plant biodiversity indices and nitrogen fertilization affect the temporal stability of community pathogen load over seven consecutive years. We found that the temporal...

Effects of three-dimensional soil heterogeneity and species composition on plant biomass and biomass allocation of grass-mixtures

Yongjie Liu, Guoe Li, Mingxia Wang, Wenjing Yan & Fujiang Hou
Soil heterogeneity significantly affects plant dynamics such as plant growth and biomass. Most studies developed soil heterogeneity in two dimensions, i.e. either horizontally or vertically. However, soil heterogeneity in natural ecosystems varies both horizontally and vertically i.e. in three dimensions. Previous studies on plant biomass and biomass allocation rarely considered the joint effects of soil heterogeneity and species composition. Thus, to investigate such joint effects on plant biomass and biomass allocation, a controlled experiment was...
