Hybrids between the indica and japonica subspecies of rice (Oryza sativa) are usually sterile, which hinders utilization of heterosis in the inter-subspecific hybrid breeding. The complex locus Sa comprises two adjacently located genes, SaF and SaM, which interact to cause abortion of pollen grains carrying the japonica allele in japonica-indica hybrids. Here we showed that silencing of SaF or SaM by RNA interference restored male fertility in indica-japonica hybrids with heterozygous Sa. We further used CRISPR/Cas9-based genome editing to knockout the SaF and SaM alleles respectively of an indica rice line to create hybrid-compatible lines...

Gene expression is precisely regulated during the inflammatory response to control infection and limit the detrimental effects of inflammation. Here, we profiled global mRNA translation dynamics in the mouse primary macrophage-mediated inflammatory response and identified hundreds of differentially translated mRNAs. These mRNAs' 3'UTRs have enriched binding motifs for several RNA-binding proteins, which implies extensive translational regulatory networks. We characterized one such protein, Zfp36, as a translation repressor...

OBJECTIVE: To evaluate the efficacy and prognostic validity for disease-specific survival (DSS) of the 8th edition American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor-node-metastasis (TNM) staging system (TNM-8) compared with the 7th edition (TNM-7) in patients with differentiated thyroid carcinoma (DTC). METHODS: The 7th and 8th editions of the TNM staging system were applied to 1613 DTC patients who underwent thyroid surgery between 1996 and 2003...

Robust and cost-effective genome editing in a diverse array of cells and model organisms is now possible thanks to the discovery of the RNA-guided endonucleases of the CRISPR-Cas system. The commonly used Cas9 of Streptococcus pyogenes shows high levels of activity but, depending on the application, has been associated with some shortcomings. Firstly, the enzyme has been shown to cause mutagenesis at genomic sequences resembling the target sequence. Secondly, the stringent requirement for a specific motif adjacent to the selected target site can limit the target range of this enzyme...

Since its introduction in 2011, Liver Imaging Reporting and Data System (LI-RADS) has become an increasingly utilized method for radiologists to categorize lesions for hepatocellular carcinoma (HCC) in patients at risk (American College of Radiology, www.acr.org/quality-safety/resources/lirads 2016). This overview article presents insight into methods of incorporating LI-RADS into an existing clinical practice, highlighting concrete ways to establish this system as a mainstay in any radiologist's evidence-based armamentarium...

This study aimed to determine: i) the correlation between objective and subjective cognition, ii) the correlates of objective and subjective cognition and iii) the predictors of discrepancy between objective and subjective cognition. Participants were non-elderly patients with major depressive disorder (MDD). We assessed subjective cognition using the Perceived Deficit Questionnaire for Depression (PDQ-D) and objective cognition using Face I and Face II tests of the Wechsler Memory Scale, 3rd edition and Digit Span and Matrix Reasoning tests of the Wechsler Intelligence Scale for Adults, 3rd edition...

Successful establishment of CRISPR/Cas9 genome editing technology in Plasmodium spp. has provided a powerful tool to transform Plasmodium falciparum into a genetically more tractable organism. Conditional gene regulation approaches are required to study the function of gene products critical for growth and erythrocyte invasion of blood stage parasites. Here we employ CRISPR/Cas9 to facilitate use of the dimerisable Cre-recombinase (DiCre) that is frequently used to mediate the excision and loss of loxP-flanked DNA sequences in a rapamycin controlled manner...

The β2-adrenergic receptor (β2AR) has provided a paradigm to elucidate how G protein-coupled receptors (GPCRs) control intracellular signaling, including the discovery that β-arrestins, which bind to ligand-activated GPCRs, are central for GPCR function. We used genome editing, conditional gene deletion, and small interfering RNAs (siRNAs) to determine the roles of β-arrestin 1 (β-arr1) and β-arr2 in β2AR internalization, trafficking, and signaling to ERK. We found that only β-arr2 was essential for β2AR internalization...

The programming of new functions into mammalian cells has tremendous application in research and medicine. Continued improvements in the capacity to sequence and synthesize DNA have rapidly increased our understanding of mechanisms of gene function and regulation on a genome-wide scale and have expanded the set of genetic components available for programming cell biology. The invention of new research tools, including targetable DNA-binding systems such as CRISPR/Cas9 and sensor-actuator devices that can recognize and respond to diverse chemical, mechanical, and optical inputs, has enabled precise control of complex cellular behaviors at unprecedented spatial and temporal resolution...

Jonathan L Schmid-Burgk
The bacterial type II Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR Associated (Cas) systems, and in particular Streptococcus pyogenes CRISPR-Cas9, have been broadly applied to edit the genome of bacterial and eukaryotic cells. Cas9, which is an RNA-guided programmable nuclease, is a powerful tool for disrupting protein-coding genes. Cas9 cleaves target sites to generate a double-strand break (DSB) that is repaired via an error-prone repair process, leading to insertion/deletion mutations and gene knockouts...

Diabetes, type 1 and type 2 (T1D and T2D), are diseases of epidemic proportions, which are complicated and defined by genetics, epigenetics, environment, and lifestyle choices. Current therapies consist of whole pancreas or islet transplantation. However, these approaches require life-time immunosuppression, and are compounded by the paucity of available donors. Pluripotent stem cells have advanced research in the fields of stem cell biology, drug development, disease modeling, and regenerative medicine, and importantly allows for the interrogation of therapeutic interventions...

The successful implementation of the advanced sequencing technology, the next generation sequencing (NGS) motivates scientists from diverse fields of biological research especially from genomics and transcriptomics in generating large genomic data set to make their analysis more robust and come up with strong inference. However, exploiting this huge genomic data set becomes a challenge for the molecular biologists. To corroborate this problem, computational software and hardware are being developed in parallel and become an integral part of life science...

African trypanosomiasis occurs in 36 countries in sub-Saharan Africa with 10,000 reported cases annually. No definitive remedy is currently available and if left untreated, the disease becomes fatal. Structural and biochemical studies of trypanosomal terminal uridylyl transferases (TUTases) demonstrated their functional role in extensive uridylate insertion/deletion of RNA. Trypanosoma brucei RNA Editing TUTase 1 (TbRET1) is involved in guide RNA 3' end uridylation and maturation, while TbRET2 is responsible for U-insertion at RNA editing sites...

Phenomenon: The integration of public health (PH) competency training into medical education, and further integration of PH and primary care, has been urged by the U.S. Institute of Medicine. However, PH competencies are numerous, and no consensus exists over which competencies are most important for adoption by current trainees. Our objective was to conduct a group concept mapping exercise with stakeholders identifying the most important and feasible PH skills to incorporate in medical and residency curricula...
