Chemical Proteomics Reveals Protein Tyrosination Extends Beyond the Alpha‐Tubulins in Human Cells**

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Protein post‐translational modifications allow cells to swiftly adjust activity and localization of proteins. Here, we developed a chemical proteomic approach to determine a protein tyrosination status using an O‐propargyl tyrosine probe. We show that tyrosination modifies previously described alpha‐tubulins with ‐EEY C‐terminal sequence together with ...

Validation of reference genes as internal control for studying viral infections in cereals by quantitative real-time RT-PCR

BMC Plant Biology, 2010
Background Reference genes are commonly used as the endogenous normalisation measure for the relative quantification of target genes. The appropriate application of quantitative real-time PCR (RT-qPCR), however, requires the use of reference genes whose ...

Dual‐Gating Strategy: Ultrasound Activation of TRPV2 Channels and Borate‐Glass‐Induced Calcium Overload for Tumor Suppression

Advanced Science, EarlyView.
A novel strategy combining borate glass and ultrasound is proposed for the precise treatment of breast cancer. The locally delivered borate glass releases Ca2⁺ ions in situ, while ultrasound activates the highly expressed transient receptor potential vanilloid 2 channels in breast cancer cells. This synergistic effect induces specific calcium overload,

Transcriptome-based screening and the optimal reference genes for real-time quantitative PCR in Rehmannia chingii and R. henryi

Biologia Plantarum, 2020
Real time quantitative PCR (qPCR) is a powerful tool for studying the expression of specific genes. The accuracy and reliability of qPCR analysis data require the selection of reference genes with stable expression.

Lactobacillus johnsonii Generates Cyclo(pro‐trp) and Promotes Intestinal Ca2+ Absorption to Alleviate CKD–SHPT

Advanced Science, EarlyView.
The mechanism map of how L.johnsonii generates cyclo(pro‐trp) to alleviate CKD–SHPT by promoting the expression of CaSR and TRPV4 in IECs, enhancing Ca2+ absorption, and negatively feedback inhibiting iPTH secretion. Abstract Patients with chronic kidney disease (CKD) are at a high risk of developing secondary hyperparathyroidism (SHPT), which may ...

In Situ Detection of Aspergillus 18S Ribosomal RNA in Invasive Pulmonary Apergillosis.

Internal Medicine, 1999
We attempted to evaluate the usefulness of in situ hybridization (ISH) in the specific diagnosis of Aspergillus pulmonary infection.We used an ISH technique using a multiple digoxigenin-incorporating probe, which was constructed by means of the polymerase chain reaction (PCR) from the 18S ribosomal RNA of Aspergillus fumigatus.We studied twelve ...

The Lipid-RNA World [PDF]

arXiv, 2012
The simplest possible beginning of abiogenesis has been a riddle from the last century, which is most successfully solved by the Lipid World hypothesis. However, origin of the next stages of evolution starting form lipids is still in dark. We propose a 'Lipid-RNA World Scenario' based on the assumption that modern stable lipid-RNA interactions are ...

Dimethyl Itaconate Alleviates Escherichia coli‐Induced Endometritis Through the Guanosine‐CXCL14 Axis via Increasing the Abundance of norank_f_Muribaculaceae

Advanced Science, EarlyView.
The research findings indicate that dimethyl itaconate (DI) alleviates Escherichia coli (E. coli) induced endometritis by modulating the gut microbiota and enriching the abundance of norank_f_Muribaculaceae, thereby increasing the production of guanosine.

Mitofusin 1 Drives Preimplantation Development by Enhancing Chromatin Incorporation of Histone H3.3

Advanced Science, EarlyView.
MFN1 exerts its function partially through histone H3.3 in early embryos. MFN1 colocalizes with PADI6, and its deficiency results in compromised cytoplasmic lattices and ribosomal subunits, leading to declined H3.3 protein level. This, in turn, hinders the incorporation of H3.3 into the embryonic genome, thereby causing failure of male pronucleus ...

Phenotypic plasticity in the Caribbean sponge Callyspongia vaginalis (Porifera: Haplosclerida)

Scientia Marina, 2010
Sponge morphological plasticity has been a long-standing source of taxonomic difficulty. In the Caribbean, several morphotypes of the sponge Callyspongia vaginalis have been observed.
