Transcriptomics is a powerful approach for functional genomics and systems biology, yet it can also be used for genetic part discovery. Here, we derive constitutive and light-regulated promoters directly from transcriptomics data of the basidiomycete red yeast Xanthophyllomyces dendrorhous CBS 6938 (anamorph Phaffia rhodozyma) and use these promoters with other genetic elements to create a modular synthetic biology parts collection for this organism.

Plant genetic transformation is essential for understanding gene functions and developing improved crop varieties. Traditional methods, often genotype-dependent, are limited by plants' recalcitrance to gene delivery and low regeneration capacity. To overcome these limitations, new approaches have emerged that greatly improve efficiency and genotype flexibility.

The reporter system has demonstrated great potential as a visible marker to monitor gene expression in both transiently and stably transformed plant tissues. Ectopic expression of the reporter leads to bright red pigmentation in plant tissues that do not naturally accumulate betalain. Unlike traditional visual markers such as β-glucuronidase (GUS), luciferase (LUC), and various fluorescent proteins, the reporter system does not require sample sacrifice or special equipment for visualizing the gene expression.

Conventional maize transformation has largely relied on immature embryos as explants, and is thus often hampered by the limited access to high-quality immature embryos year-round. Here, we present a detailed protocol using seedling leaf whorls as alternative explants for tropical maize inbred transformation. This approach involves the use of a cassette that drives the expression of the morphogenic transcription factors (MTFs) () and (), which have been shown to greatly enhance transformation efficiency.

The introduction of maize genetic transformation in the 1990s brought forth a powerful tool for crop improvement and a deeper understanding of plant genetics. Despite decades of genetics research, however, and the promise of CRISPR-mediated gene editing, maize transformation currently faces several challenges, such as genotype dependence and limitations in explant availability. Indeed, although the most commonly used method, immature embryo transformation, has been improved through optimization of tissue culture media composition and selection methods, the approach is only applicable to a limited number of public genotypes, including B104 and Hi II.

Electrocardiogram (ECG) is one of the reference cardiovascular diagnostic exams. However, the ECG signal is very prone to being distorted through different sources of artifacts that can later interfere with the diagnostic. For this reason, signal quality assessment (SQA) methods that identify corrupted signals are critical to improve the robustness of automatic ECG diagnostic methods.

Ischemic events can culminate in acute myocardial infarction, which is generated by irreversible cardiac lesions that cannot be restored due to the limited regenerative capacity of the heart. Cardiac cell therapy aims to replace injured or necrotic cells with healthy and functional cells. Tissue engineering and cardiovascular regenerative medicine propose therapeutic alternatives using biomaterials that mimic the native extracellular environment and improve cellular and tissue functionality.

-mediated transformation is an essential tool for functional genomics studies and crop improvements. Recently developed ternary vector systems, which consist of a T-DNA vector and a compatible virulence () gene helper plasmid (ternary helper), demonstrated that including an additional gene helper plasmid into disarmed strains significantly improves T-DNA delivery efficiency, enhancing plant transformation. Here, we report the development of a new ternary helper and thymidine auxotrophic strains to boost -mediated plant transformation efficiency.

This study aimed to investigate the potential anti-inflammatory properties of aqueous extract of (AEMV) using various animal models. Several inflammatory models including xylene-induced ear edoema, carrageenan-induced paw edoema, and Freund's adjuvant-induced arthritis were employed to evaluate the anti-inflammatory effects of AEMV. LC-MS/MS of AEMV revealed that the major component was Marrubiin, a diterpenoid lactone.

To enhance the enzymatic digestibility of polyethylene terephthalate (PET), which is highly oriented and crystallized, a polyethylene glycol (PEG) surfactant of varying molecular weights was utilized to improve the stability of mutant cutinase from Humicola insolens (HiC) and to increase the accessibility of the enzyme to the substrate. Leveraging the optimal conditions for HiC hydrolysis of PET, the introduction of 1 % w/v PEG significantly increased the yield of PET hydrolysis products. PEG600 was particularly effective, increasing the yield by 64.

In Morocco, the abundance of low-value varieties in the oases may provide an opportunity to capitalize on this richness to create new nutraceutical food products. In this context, the phenolic profile and antioxidant capacity of four Moroccan date varieties were analyzed. Our results indicate that the levels of total polyphenols, total flavonoids and total condensed tannins vary, respectively, from 91.

Ensuring plant resilience to drought and phosphorus (P) stresses is crucial to support global food security. The phytobiome, shaped by selective pressures, harbors stress-adapted microorganisms that confer host benefits like enhanced growth and stress tolerance. Intercropping systems also offer benefits through facilitative interactions, improving plant growth in water- and P-deficient soils.

Efficient genetic transformation is a prerequisite for rapid gene functional analyses and crop trait improvements. We recently demonstrated that new T-DNA binary vectors with /G418 selection and a compatible helper plasmid can efficiently transform maize inbred B104 using our rapid -mediated transformation method. In this work, we implemented the non-integrating () T-DNA vector method for -mediated B104 transformation and tested its potential for recalcitrant inbred B73 transformation and gene editing.

Sarcoidosis is a complex inflammatory multisystem disease of unknown etiology that is characterised by epithelioid cell granulomatous lesions affecting various organs, mainly the lungs. In general, sarcoidosis is asymptomatic, but some cases result in severe complications and organ failure. So far, no accurate and validated modelling for clinical and pathohistological manifestations of sarcoidosis is suggested.

It is impractical to develop a new parts collection for every potential host organism. It is well-established that gene expression parts, like genes, are qualitatively transferable, but there is little quantitative information defining transferability. Here, we systematically quantified the behavior of a parts set across multiple hosts.

Human cytomegalovirus (HCMV) is an opportunistic pathogen that infects most of the population. The complex 236 kbp genome encodes more than 170 open reading frames, whose expression is temporally regulated by both viral transcriptional regulators and cellular factors that control chromatin and transcription. Here, we have used state of the art genomic technologies to investigate the viral transcriptome in conjunction with 2 key transcriptional regulators: Pol II and H3K27Ac.

Recent advances in the genome-editing tools have demonstrated a great potential for accelerating functional genomics and crop trait improvements, but the low efficiency and genotype dependence in plant transformation hinder practical applications of such revolutionary tools. Morphogenic transcription factors (MTFs) such as Baby boom, Wuschel2, GROWTH-REGULATING FACTOR5, GROWTH-REGULATING FACTOR4 and its cofactor GRF-INTERACTING FACTOR1, and Wuschel-homeobox 5 related have been shown to greatly enhance plant transformation efficiency and expand the range of amenable species and genotypes. This review will summarize recent advancements in plant transformation technologies with an emphasis on the strategies developed for genotype-flexible transformation methods utilizing MTFs for both monocots and dicot plant species.

This article presents silica nanoparticles for the sustained release of AMACR antibody-conjugated and free doxorubicin (DOX) for the inhibition of prostate cancer cell growth. Inorganic MCM-41 silica nanoparticles were synthesized, functionalized with phenylboronic acid groups (MCM-B), and capped with dextran (MCM-B-D). The nanoparticles were then characterized using Fourier-transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, zeta potential analysis, nitrogen sorption, X-ray diffraction, and thermogravimetric analysis, before exploring their potential for drug loading and controlled drug release.
