AI Article Synopsis
- The study investigates a mutant strain of Medicago truncatula (lss) that shows increased nodulation due to cis-silencing of the SUNN gene.
- Previous analysis did not reveal significant differences in methylation of the SUNN promoter, prompting further research on a larger genomic area (810 kB).
- The findings include data on methylation distribution, differentially methylated cytosines, and overall gene methylation patterns, providing a valuable reference for future studies on methylation in this species.
Article Abstract
Objectives: Earlier work in our lab identified a spontaneous mutant (likesunnsupernodulator-lss) in Medicago truncatula, resulting in increased nodulation. Molecular genetic evidence indicated the phenotype was due to an unknown lesion resulting in cis-silencing of the SUNN gene. Altered methylation of the promoter was suspected, but analysis of the SUNN promoter by bisulfite sequencing at the time of publication revealed no significant methylation differences between the SUNN promoter in wild type and lss plants. Using advances in methylome generation we compared the methylome of wild type and the lss mutant in the larger 810 kB area of the genome where lss maps.
Data Description: The data show the distribution of types of methylation across the entire genome between A17 wild type and lss mutants, the number of differentially methylated cytosines between genotypes, and the overall pattern of gene methylation between genotypes. We expect the wild type data will be especially useful as a reference for other investigations of methylation using M. truncatula.

We previously documented successful resolution of skeletal and dental disease in the infantile and late-onset murine models of hypophosphatasia (HPP), with a single injection of an adeno-associated serotype 8 vector encoding mineral-targeted TNAP (AAV8-TNAP-D10). Here, we conducted dosing studies in both HPP mouse models. A single escalating dose from 4x108 up to 4x1010 (vg/b) was intramuscularly injected into 4-day-old Alpl-/- mice (an infantile HPP model) and a single dose from 4x106 up to 4x109 (vg/b) was administered to 8-week-old AlplPrx1/Prx1 mice (a late-onset HPP model).

The p53 protein is regarded as the "Guardian of the Genome," but its mutation is tumor progression and present in more than half of malignant tumors. The pro-metastatic property of mutant p53 makes a strong argument for targeting mutant p53 with new therapeutic strategies. However, mutant p53 was considered as a challenging target for drug discovery due to the lack of small molecular binding pockets.

Background: A loss-of-functional mutation (W1183R) in human complement factor H (CFH) is associated with complement-associated hemolytic uremic syndrome; mice carrying a similar mutation (W1206R) in CFH also develop thrombotic microangiopathy but its plasma von Willebrand factor (VWF) multimer sizes were dramatically reduced. The mechanism underlying such a dramatic change in plasma VWF multimer distribution in these mice is not fully understood.
Objective And Methods: To determine the VWF and CFH interaction and how CFH proteins affect VWF multimer distribution, we employed recombinant protein expression, purification, and various biochemical and biophysical tools.

Coupling interactions between the alpha (α) subunit of the polymerase III core (α-Pol III core) and the tau (τ) subunit of the clamp loader complex (τ-CLC) are vital for efficient and rapid DNA replication in Escherichia coli (E. coli). Specific and targeted mutations in the C-terminal τ-interaction region of the Pol III α-subunit disrupted efficient coupled rolling circle DNA synthesis in vitro and caused significant genomic defects in CRISPR-Cas9 dnaE edited cell strains.

Most adhesion GPCRs undergo autoproteolytic cleavage during receptor biosynthesis, resulting in non-covalently bound N- and C-terminal fragments (NTF and CTF) that remain associated during receptor trafficking to the plasma membrane. While substantial evidence supports increased G protein signaling when just the CTF is expressed, there is an ongoing debate about whether NTF removal is required to initiate signaling in the context of the wild-type receptor. Here, we use adhesion GPCR latrophilin-3 (ADGRL3) as a model receptor to investigate tethered agonist-mediated activation.
