PTGS is dispensable for the initiation of epigenetic silencing of an active transposon in Arabidopsis

EMBO Reports
Transposable elements (TEs) are repressed in plants through transcriptional gene silencing (TGS), maintained epigenetic silencing marks such as DNA methylation.

Analysis of prostaglandin-endoperoxide synthase-2 gene polymorphisms and risk of cervical cancer in an East Indian population: A case–control study

Asian Journal of Oncology, 2017
Background: The prostaglandin-endoperoxide synthase-2 (PTGS-2) gene appears to play a role in inflammation or tumor and mitogenesis. Genetic polymorphisms in PTGS-2 might contribute to differential PTGS-2 expression and subsequent interindividual ...

Key Amino Acids for Pepper Vein Yellows Virus P0 Protein Pathogenicity, Gene Silencing, and Subcellular Localization

Frontiers in Microbiology, 2021
Pepper vein yellows virus (PeVYV) is a newly recognized Polerovirus extracted from Chinese pepper. The symptoms of PeVYV-infested pepper plants comprise intervein yellow staining, leaf curl formation and other malformations, and leaf internodal shrinkage,

The origin and effect of small RNA signaling in plants [PDF]

, 2012
Given their sessile condition, land plants need to integrate environmental cues rapidly and send signal throughout the organism to modify their metabolism accordingly. Small RNA (sRNA) molecules are among the messengers that plant cells use to carry such

The SGS3 protein involved in PTGS finds a family

BMC Bioinformatics, 2002
Background Post transcriptional gene silencing (PTGS) is a recently discovered phenomenon that is an area of intense research interest. Components of the PTGS machinery are being discovered by genetic and bioinformatics approaches, but the picture is not

Detailed comparison of robotic and endoscopic transaxillary thyroidectomy

Asian Journal of Surgery, 2020
Summary: Background: Robotic thyroidectomy is increasingly used for patients with papillary thyroid carcinoma (PTC). We compared the differences between robotic and endoscopic transaxillary thyroidectomy with regard to surgical procedures. Methods: This

Role of RNA Interference (RNAi) in the Moss Physcomitrella patens [PDF]

, 2013
RNA interference (RNAi) is a mechanism that regulates genes by either transcriptional (TGS) or posttranscriptional gene silencing (PTGS), required for genome maintenance and proper development of an organism.

Cross‐Cultural Influences on the Association Between Rumination and Psychopathology: A Systematic Review

Journal of Clinical Psychology, EarlyView.
ABSTRACT Rumination is a transdiagnostic process associated with psychopathology. While culture shapes cognitive and emotion processing, cultural influences on rumination remain unclear. Therefore, this systematic review aimed to examine cultural differences in the association between rumination and psychopathology.

Strain, procedures, and tools for reproducible genetic transformation and genome editing of the emerging plant model Spirodela polyrhiza. [PDF]

New Phytol
Summary Duckweeds (Lemnaceae) have excellent potential for fundamental and applied research due to ease of cultivation, small size, and continuous fast clonal growth. However, their usage as model organisms and platforms for biotechnological applications is often limited by the lack of universal genetic manipulation methods necessary for transgene ...

Biomaterials for resolution of peri‐implantitis: Consensus report of Workgroup 2 of the IADR Implantology Research Group Best Evidence Consensus Symposium on Peri‐Implant Disease and Its Treatment

Journal of Periodontology, EarlyView.
Abstract Background Peri‐implantitis is a destructive disease affecting the tissues surrounding dental implants. Biomaterials may be applied during surgical treatment to reconstruct bony defects and support soft tissue healing. However, current evidence is unclear if these treatments increase the likelihood of peri‐implantitis resolution.
