Human essential hypertension: no significant association of polygenic risk scores with antihypertensive drug responses

Heini Sánez Tähtisalo, Sanni Ruotsalainen, Nina Mars et al. · 2020 · Scientific Reports

Polygenic risk scores (PRSs) for essential hypertension, calculated from > 900 genomic loci, were recently found to explain a significant fraction of hypertension heritability and complications. To investigate whether variation of hypertension PRS also captures variation of antihypertensive drug responsiveness, we calculated two different PRSs for both systolic and diastolic blood pressure: one based on the top 793 independent hypertension-associated single nucleotide polymorphisms and another based on over 1 million genome-wide variants. Using our pharmacogenomic GENRES study comprising four

Preoperative palsy score has no significant association with survival in non-small-cell lung cancer patients with spinal metastases who undergo spinal surgery

Yen‐Jen Chen, Hsien‐Te Chen, Horng‐Chaung Hsu · 2015 · Journal of Orthopaedic Surgery and Research

BACKGROUND: Survival is a key factor physicians consider when selecting a treatment modality for the treatment of spinal metastases. Various assessment systems can predict length of survival and facilitate selection of the most appropriate treatment. Spinal palsy is a prognostic parameter in the Tokuhashi scoring system but not in the Tomita scoring system. A limitation of these scoring systems is that studies of them have included different tumor types. The aim of this study was to evaluate the usefulness of preoperative neurological status as a prognostic factor in non-small-cell lung cancer

Significant differences in terms of codon usage bias between bacteriophage early and late genes: a comparative genomics analysis

Oriah Mioduser, Eli Goz, Tamir Tuller · 2017 · BMC Genomics

BACKGROUND: Viruses undergo extensive evolutionary selection for efficient replication which effects, among others, their codon distribution. In the current study, we aimed at understanding the way evolution shapes the codon distribution in early vs. late viral genes in terms of their expression during different stages in the viral replication cycle. To this end we analyzed 14 bacteriophages and 11 human viruses with available information about the expression phases of their genes. RESULTS: We demonstrated evidence of selection for distinct composition of synonymous codons in early and late vi

Osmotic stress in colony and planktonic cells of Pseudomonas putida mt-2 revealed significant differences in adaptive response mechanisms

Nancy Hachicho, Astrid Birnbaum, Hermann J. Heipieper · 2017 · AMB Express

Planktonic cells and those grown on surfaces (or as colony biofilm) are known to show significant differences regarding growth behavior, cell physiology, gene expression and stress tolerance. In order to compare stress behavior of different growth forms, shake cultures for planktonic growth and agar plate cultivation for colony growth, were carried out with the well investigated model organism, Pseudomonas putida mt-2. Cells were exposed to sodium chloride to cause osmotic stress as one main environmental stressor bacteria have to cope with when growing in soil. Planktonic cells were more tole

MTEP, a Selective mGluR5 Antagonist, Had a Neuroprotective Effect but Did Not Prevent the Development of Spontaneous Recurrent Seizures and Behavioral Comorbidities in the Rat Lithium–Pilocarpine Model of Epilepsy

A. V. Dyomina, Anna A. Kovalenko, Maria V. Zakharova et al. · 2022 · International Journal of Molecular Sciences

Metabotropic glutamate receptors (mGluRs) are expressed predominantly on neurons and glial cells and are involved in the modulation of a wide range of signal transduction cascades. Therefore, different subtypes of mGluRs are considered a promising target for the treatment of various brain diseases. Previous studies have demonstrated the seizure-induced upregulation of mGluR5; however, its functional significance is still unclear. In the present study, we aimed to clarify the effect of treatment with the selective mGluR5 antagonist 3-[(2-methyl-1,3-thiazol-4-yl)ethynyl]-pyridine (MTEP) on epile

Comparative transcriptome analysis reveals significant differences in the regulation of gene expression between hydrogen cyanide- and ethylene-treated Arabidopsis thaliana

Lulu Yu, Yang Liu, Fei Xu · 2019 · BMC Plant Biology

BACKGROUND: Hydrogen cyanide (HCN) is a small gaseous molecule that is predominantly produced as an equimolar co-product of ethylene (ET) biosynthesis in plants. The function of ET is of great concern and is well studied; however, the function of HCN is largely unknown. Similar to ET, HCN is a simple and diffusible molecule that has been shown to play a regulatory role in the control of some metabolic processes in plants. Nevertheless, it is still controversial whether HCN should be regarded as a signalling molecule, and the cross-talk between HCN and ET in gene expression regulation remains u

Different Threshold of Malignancy for RAS-like Thyroid Tumors Causes Significant Differences in Thyroid Nodule Practice

Kennichi Kakudo · 2022 · Cancers

Histopathological diagnosis of papillary thyroid carcinomas (PTCs) is prone to significant observer variation due to different thresholds of RAS-like nuclear changes among pathologists. This gap recently widened due to a defensive attitude by Western pathologists where malpractice litigation is significant. Cases with delicate RAS-like nuclear changes are follicular adenomas when they are noninvasive, follicular carcinomas when invasive, and follicular variant PTCs when they have fully developed PTC-type nuclear features in Asian practice. The different diagnostic threshold of PTC nuclear feat
