In plants, cell-surface receptors control immunity and development through the recognition of extracellular ligands. Leucine-rich repeat receptor-like proteins (LRR-RLPs) constitute a large multigene family of cell-surface receptors. Although this family has been intensively studied, a limited number of ligands has been identified so far, mostly because methods used for their identification and...

Nucleotide-binding leucine-rich repeat sequence (NBS-LRR) protein is the main immune receptor in plants and participates plant resistance to pathogens. When NBS-LRR activated by pathogen’s effector protein, its conformation changes from an inhibitory state state, then it activates downstream signal transduction initiates defense responses inhibit growth of The has major three domains: NBS, LRR ...

We have screened the genome of the marine diatom Phaeodactylum tricornutum for gene models encoding proteins exhibiting leucine-rich repeat (LRR) structures. In order to reveal the functionality of these proteins, their amino acid sequences were scanned for known domains and for homologies to other proteins. Additionally, proteins were categorized into different LRR-families according to the va...

Introduction: It remains controversial on high risks for early breast cancer patients with one to three axillary nodes after mastectomy who is predisposition to locoregional recurrence. The present study is to investigate the relationship between primary tumor site and loco-regional recurrence (LRR) and explore the predictive value of clinicopathological characteristics in LRR for early breast ...

PURPOSE The purpose of this study is to determine whether breast cancer subtype can affect locoregional recurrence (LRR) and ipsilateral breast tumor recurrence (IBTR) after neoadjuvant chemotherapy (NAC) and breast-conserving therapy (BCT). MATERIALS AND METHODS We evaluated 335 consecutive patients with clinical stage II-III breast cancer who received NAC plus BCT from 2002 to 2009. Patient...

PURPOSE This study was designed to investigate the relationship between molecular subtype and locoregional recurrence (LRR) in patients with early-stage breast cancer with 1-3 positive axillary lymph nodes (ALNs) and improve the individualized indications for postmastectomy radiotherapy (PMRT). METHODS The records of 701 patients with pT1-2N1M0 breast cancer who did not undergo PMRT were retr...

Background: Evidence based guidelines for the optimal management of breast cancer locoregional recurrence (LRR) are limited, with potential variation in clinical practice. This national practice questionnaire (NPQ) was designed to establish current UK multidisciplinary teams (MDTs) regarding LRR management.

Thirteen alleles (L, L1 to L11, and LH) from the flax L locus, which encode Toll/interleukin-1 receptor homology-nucleotide binding site-leucine-rich repeat (TIR-NBS-LRR) rust resistance proteins, were sequenced and compared to provide insight into their evolution and into the determinants of gene-for-gene resistance specificity. The predicted L6 and L11 proteins differ solely in the LRR region...

Venography is the current standard for the diagnosis of deep vein thrombosis (DVT). Noninvasive tests have differing sensitivity and specificity, are technically demanding, and may be subject to variability in interpretation. Light reflection rheography (LRR) is a noninvasive method utilizing light-emitting diodes and a sensor to measure light reflected from the skin surface. The intensity of r...

Plant nucleotide binding and leucine-rich repeat (NB-LRR) proteins contain a region of homology known as the ARC domain located between the NB and LRR domains. Structural modeling suggests that the ARC region can be subdivided into ARC1 and ARC2 domains. We have used the potato (Solanum tuberosum) Rx protein, which confers resistance to Potato virus X (PVX), to investigate the function of the A...
