ANKRD11 binding to cohesin suggests a connection between KBG syndrome and Cornelia de Lange syndrome.

Proc Natl Acad Sci U S A

January 2025

Shenzhen Key Laboratory of Biomolecular Assembling and Regulation, Department of Neuroscience, School of Life Sciences, Southern University of Science and Technology, Shenzhen 518055, China.

Ankyrin Repeat Domain-containing Protein 11 () is a causative gene for KBG syndrome, a significant risk factor for Cornelia de Lange syndrome (CdLS), and a highly confident autism spectrum disorder gene. Mutations of lead to developmental abnormalities in multiple organs/tissues including the brain, craniofacial and skeletal bones, and tooth structures with unknown mechanism(s). Here, we find that ANKRD11, via a short peptide fragment in its N-terminal region, binds to the cohesin complex with a high affinity, implicating why mutation can cause CdLS.

The stability of proteins and small peptides depends on the way they interact with the surrounding water molecules. For small peptides, such as -helical polyalanine (polyALA), water molecules can weaken the intramolecular hydrogen-bonds (HB) formed between the peptide backbone O and NH groups which are responsible for the -helix structure. Here, we perform molecular dynamics simulations to study the hydration of polyALA, polyserine (polySER), and other homopolymer peptide -helices at different temperatures and pressures.

Distinct tau amyloid assemblies underlie diverse tauopathies but defy rapid classification. Cell and animal experiments indicate tau functions as a prion, as different strains propagated in cells cause unique, transmissible neuropathology after inoculation. Strain amplification requires compatibility of the monomer and amyloid template.

By a simple condensation reaction, the receptor with anthraquinone moiety was synthesized and its sensing properties were explored in the anion sensing studies via colorimetric, UV-vis studies, fluorescence studies, and DFT calculations. The synthesized receptor senses both acetate and hypochlorite ions in DMSO medium. By the addition of all anions into the receptor the colour change was observed from pink to light purple colour for acetate ion and pink to light blue for hypochlorite ion.

Introduction: 5-aminolevulinic acid (5-ALA) fluorescence used in glioma surgery has different intensities within tumors and among different patients, some molecular and external factors have been implicated, but there is no clear evidence analyzing the difference of fluorescence according to glioma molecular characteristics. This study aimed to compare molecular factors of glioma samples with fluorescence intensity to identify potential cofounders and associations with clinically relevant tumor features.

Methods: Tumor samples of high-grade glioma patients operated using 5-ALA for guided resection were included for comparative analysis of fluorescence intensity and molecular features.

Single-Template Molecularly Imprinted Chiral Sensor for Enantioselective Recognition of Various Chiral Amino Acids Based on a Dummy Template Strategy.

Anal Chem

January 2025

Jiangsu Key Laboratory of Advanced Catalytic Materials and Technology, School of Petrochemical Engineering, Changzhou University, Changzhou 213164, China.

Designing single-template molecularly imprinted chiral sensors for the enantioselective recognition of various chiral amino acids (AAs) is of great importance for chiral analysis. Here, a dummy template-based chiral sensor is developed by using l-alanine (l-Ala) as the dummy template and poly(-phenylenediamine) as the imprinting layer, which can be used for the enantioselective recognition of various chiral AAs such as Ala, tryptophan (Trp), tyrosine (Tyr), cysteine (Cys), and arginine (Arg). Compared with conventional single-template molecularly imprinted chiral sensors, the designed single-template chiral sensor shows great universality for the recognition of chiral AAs since all chiral AAs possess an Ala-analogous segment.

Laboratorio de Terapias Fotoasistidas, Centro de Investigaciones sobre Porfirinas y Porfirias (CIPYP), Hospital de Clínicas José de San Martín and CONICET, Universidad de Buenos Aires, Ciudad de Buenos Aires, Argentina.

Photodynamic inactivation (PDI) combines the use of photosensitizers with visible light to produce reactive oxygen species that effectively eliminate pathogens. To investigate the impact of near- infrared therapy (NIRT) on heme biosynthesis and permeability of the pro-photosensitizers 5-aminolevulinic acid (ALA) and Hexyl-ALA (H-ALA) through biofilms, we applied sub-lethal conditions for both NIRT and PDI to maintain intact bacterial viability. During NIRT, the temperature remained below 37°C, permitting rapid heating (ΔT = 11°C) without causing thermal damage.

In situ vaccine (ISV) can activate the anti-tumor immune system by inducing immunogenic cell death (ICD) at the tumor site. However, the development of tumor ISV still faces challenges due to insufficient tumor antigens released by tumor cells and the existence of tumor immunosuppressive microenvironment (TIME). Targeting the STING pathway has been reported to enhance the adjuvant effects of in situ tumor vaccines by initiating innate immunity.

Raman, ROA, and luminescence spectra of chiral lanthanide complexes with L- and D-alanine.

Spectrochim Acta A Mol Biomol Spectrosc

January 2025

Laboratory for Spectroscopy, Molecular Modeling and Structure Determination, Institute of Nuclear Chemistry and Technology, 16 Dorodna Street, 03-195 Warsaw, Poland. Electronic address:

The Raman spectra of lanthanide [Ln(HO)(Ala)](ClO) crystals were measured with 488, 532, 633, and 1064 nm laser lines, and ROA of complexes in water were collected using 532 nm excitation. As in IR and VCD, ν(CO) stretching and β(OCO) bending vibration bands showed a tendency typical to the lanthanide contraction effect. However, in Raman, the effect is less pronounced than the IR spectrum because it is strongly perturbed by lanthanide ion luminescence, which comes from the 4f → 4f transitions.

Modulatory effect of Echium plantagineum oil on the n-3 LC-PUFA biosynthetic capacity of chicken (Gallus gallus).

Departamento de Biología Animal, Edafología y Geología, Universidad de La Laguna. Avenida Astrofísico Francisco Sánchez s/n, 38206 La Laguna, Tenerife, Spain.

Poultry can be a sustainable source of eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) through the bioconversion of dietary alpha-linolenic acid (ALA, 18:3n-3). However, this process is currently limited by the high n-6/n-3 ratio in poultry diets affecting the competition between n-6 and n-3 fatty acids (FA) for the same biosynthetic enzymes, and the rate-limiting Δ6 desaturase which act at both, the first and final steps of DHA synthesis pathway. Echium plantagineum oil (EO) is an unusual source of stearidonic acid (SDA, 18:4n-3) which bypasses the first Δ6 desaturase step potentially increasing n-3 long-chain polyunsaturated fatty acids (LC-PUFA) synthesis.

Omega-3 fatty acids supplementation from late pregnancy to early lactation attenuates the endocannabinoid system and immune proteome in preovulatory follicles and endometrium of Holstein dairy cows.

Activation of the endocannabinoid system (ECS) elicits negative effects on the reproductive system in mammals. Omega-3 (n-3) fatty acid (FA) supplementation lowers ECS activation and has anti-inflammatory effects. Thus, we hypothesized that supplementing cows with n-3 FA will downregulate components of the ECS and immune system in preovulatory follicles and in the endometrium.

Background & Aims: Erythropoietic protoporphyria (EPP) is caused by mutations in ferrochelatase which inserts iron into protoporphyrin-IX (PP-IX) to generate heme. EPP is characterized by PP-IX accumulation, skin photosensitivity, cholestasis, and end-stage liver disease. Despite available drugs that address photosensitivity, treatment of EPP-related liver disease remains an unmet need.
