Department of Cardiology, The Xiamen Cardiovascular Hospital of Xiamen University, No. 2999 Jinshan Road, Xiamen, 361000, Fujian, China.

Dyslipidemia is being identified as the most important factors of several health problems, such as obesity, diabetes mellitus, and cardiovascular diseases (CVD), which are always grouped together as cardio-metabolic disorder diseases. Consistently, dyslipidemia has become one of the most rising crisis of general health. Recently, it is worth noting that both genome-wide association studies (GWAS) and experimental research are being taken advantage to elucidate the potential genetic mechanisms of dyslipidemia and to identify new gene loci which contribute to the development of cardio-metabolic disorder diseases.

Genome-wide gene-diet interaction analysis in the UK Biobank identifies novel effects on Hemoglobin A1c.

Hum Mol Genet 2021 Apr 16. Epub 2021 Apr 16.

Programs in Metabolism and Medical & Population Genetics, Broad Institute of Harvard and MIT, Cambridge, Massachusetts, United States of America.

Diet is a significant modifiable risk factor for type 2 diabetes (T2D), and its effect on disease risk is under partial genetic control. Identification of specific gene-diet interactions (GDIs) influencing risk biomarkers such as glycated hemoglobin (HbA1c) is a critical step towards precision nutrition for T2D prevention, but progress has been slow due to limitations in sample size and accuracy of dietary exposure measurement. We leveraged the large UK Biobank (UKB) cohort and a diverse group of dietary exposures, including 30 individual dietary traits and 8 empirical dietary patterns, to conduct genome-wide interaction studies in ~ 340 000 European-ancestry participants to identify novel GDIs influencing HbA1c.

Impact of variant-level batch effects on identification of genetic risk factors in large sequencing studies.

PLoS One 2021 16;16(4):e0249305. Epub 2021 Apr 16.

Division of Computational Biology, Department of Quantitative Health Sciences, Mayo Clinic, Jacksonville, Florida, United States of America.

Genetic studies have shifted to sequencing-based rare variants discovery after decades of success in identifying common disease variants by Genome-Wide Association Studies using Single Nucleotide Polymorphism chips. Sequencing-based studies require large sample sizes for statistical power and therefore often inadvertently introduce batch effects because samples are typically collected, processed, and sequenced at multiple centers. Conventionally, batch effects are first detected and visualized using Principal Components Analysis and then controlled by including batch covariates in the disease association models. Read More

Hedgehog signaling pathway gene variant influences bronchopulmonary dysplasia in extremely low birth weight infants.

World J Pediatr 2021 Apr 16. Epub 2021 Apr 16.

Newborn Medicine Division, The Regional Neonatal Intensive Care Unit, Maria Fareri Children's Hospital At Westchester Medical Center, Valhalla, NY, USA.

Background: Genome wide association study identified hedgehog interacting protein gene (HHIP) variants with chronic obstructive pulmonary disease and asthma. Loss of HHIP, a key regulator of the hedgehog signaling pathway, leads to impaired lung morphogenesis and lethality in animal models, through unimpeded sonic hedgehog expression blocking mesenchymal-expressed fibroblast growth factor 10 (FGF10). Since bronchopulmonary dysplasia (BPD) is also associated with altered lung development and worsens with stimuli including mechanical ventilation, reactive oxygen species, and inflammation, HHIP and FGF10 may be candidate genes.

Estrogen Receptor Beta Influences the Inflammatory p65 Cistrome in Colon Cancer Cells.

Front Endocrinol (Lausanne) 2021 30;12:650625. Epub 2021 Mar 30.

Science for Life Laboratory, Department of Protein Science, KTH Royal Institute of Technology, Solna, Sweden.

Inflammation is a primary component of both initiation and promotion of colorectal cancer (CRC). Cytokines secreted by macrophages, including tumor necrosis factor alpha (TNFα), activates the pro-survival transcription factor complex NFκB.

A genome-wide atlas of co-essential modules assigns function to uncharacterized genes.

Nat Genet 2021 Apr 15. Epub 2021 Apr 15.

Department of Genetics, Stanford University, Stanford, CA, USA.

A central question in the post-genomic era is how genes interact to form biological pathways. Measurements of gene dependency across hundreds of cell lines have been used to cluster genes into 'co-essential' pathways, but this approach has been limited by ubiquitous false positives. In the present study, we develop a statistical method that enables robust identification of gene co-essentiality and yields a genome-wide set of functional modules. Read More

Genome-wide specificity of prime editors in plants.

Nat Biotechnol 2021 Apr 15. Epub 2021 Apr 15.

State Key Laboratory of Plant Cell and Chromosome Engineering, Center for Genome Editing, Institute of Genetics and Developmental Biology, Innovation Academy for Seed Design, Chinese Academy of Sciences, Beijing, China.

Although prime editors (PEs) have the potential to facilitate precise genome editing in therapeutic, agricultural and research applications, their specificity has not been comprehensively evaluated. To provide a systematic assessment in plants, we first examined the mismatch tolerance of PEs in plant cells and found that the editing frequency was influenced by the number and location of mismatches in the primer binding site and spacer of the prime editing guide RNA (pegRNA). Assessing the activity of 12 pegRNAs at 179 predicted off-target sites, we detected only low frequencies of off-target edits (0. Read More
