Pole position: How plant cells polarize along the axes.

Plant Cell 2021 Aug 2. Epub 2021 Aug 2.

Laboratory of Biochemistry, Wageningen University, Stippeneng 4, 6703WE Wageningen, the Netherlands.

Having a sense of direction is a fundamental cellular trait that can determine cell shape, division orientation, or function, and ultimately the formation of a functional, multicellular body. Cells acquire and integrate directional information by establishing discrete subcellular domains along an axis with distinct molecular profiles, a process known as cell polarization. Insight into the principles and mechanisms underlying cell polarity has been propelled by decades of extensive research mostly in yeast and animal models. Read More

Facile surface functional polyetheretherketone with antibacterial and immunoregulatory activities for enhanced regeneration toward bacterium-infected bone destruction.

Drug Deliv 2021 Dec;28(1):1649-1663

Department of Orthopedic Surgery, Fujian Medical University Union Hospital, Fuzhou, China.

Existing biologically inert or unmodified implants to treat infectious bone defects or osteomyelitis still cannot effectively solve bacterial infection and osseointegration. In this work, a simple co-deposition strategy was developed to modify porous polyetheretherketone (PEEK) with improved antibacterial activity and controllable immunoregulatory ability. After PEEK was treated by HSO to obtain porous PEEK (SPEEK), the self-polymerization of dopamine was operated on SPEEK in the solution of dopamine and gentamicin sulfate (GS) to prepare polydopamine (pDA) and GS layer-modified SPEEK (labeled as SPEEK-pDA-GS).

Comput Methods Biomech Biomed Engin 2021 Aug 2:1-9. Epub 2021 Aug 2.

Key Laboratory for Biomechanics and Mechanobiology of Ministry of Education, School of Biological Science and Medical Engineering, Beihang University, Beijing, P. R. China.

Multi-level spinal fusion has been reported in some cases to lead to adjacent segment disease (ASD) and proximal junctional kyphosis (PJK). The purpose of this study was to demonstrate a polyether-ether-ketone (PEEK) rod fixation system implanted adjacent to a two-level lumbar fusion would have a lower risk of PJK than three-level lumbar fusion, which was investigated by comparing the biomechanical effects on the adjacent level after surgical procedures. Four finite element (FE) models of the lumbar-sacral spine (intact model (INT), L4-S1 fusion model (L4-S1 FUS), L3-S1 fusion model (L3-S1 FUS), and single-level PEEK rod semi-rigid fixation adjacent to L4-S1 fusion model (FUSPRF)) were established.

An inducible Cldn11-CreER mouse line for selective targeting of lymphatic valves.

Genesis 2021 Aug 2:e23439. Epub 2021 Aug 2.

Department of Immunology, Genetics and Pathology, Uppsala University, Uppsala, Sweden.

Luminal valves of collecting lymphatic vessels are critical for maintaining unidirectional flow of lymph and their dysfunction underlies several forms of primary lymphedema. Here, we report on the generation of a transgenic mouse expressing the tamoxifen inducible CreER under the control of Cldn11 promoter that allows, for the first time, selective and temporally controlled targeting of lymphatic valve endothelial cells. We show that within the vasculature CLDN11 is specifically expressed in lymphatic valves but is not required for their development as mice with a global loss of Cldn11 display normal valves in the mesentery.

Piwi-piRNA complexes induce stepwise changes in nuclear architecture at target loci.

EMBO J 2021 Aug 2:e108345. Epub 2021 Aug 2.

Department of Molecular Biology, Keio University School of Medicine, Tokyo, Japan.

PIWI-interacting RNAs (piRNAs) are germline-specific small RNAs that form effector complexes with PIWI proteins (Piwi-piRNA complexes) and play critical roles for preserving genomic integrity by repressing transposable elements (TEs). Drosophila Piwi transcriptionally silences specific targets through heterochromatin formation and increases histone H3K9 methylation (H3K9me3) and histone H1 deposition at these loci, with nuclear RNA export factor variant Nxf2 serving as a co-factor. Using ChEP and DamID-seq, we now uncover a Piwi/Nxf2-dependent target association with nuclear lamins. Read More
