A reciprocal feedback of miR-548ac/YB-1/Snail induces EndMT of HUVECs during acidity microenvironment

open access: yesCancer Cell International, 2021
Background Researches indicated the process of Endothelial-Mesenchymal-Transition (EndMT) of vascular endothelial cells (ECs) was critically involved in the progression of tumor. ECs demonstrated functional and phenotypic heterogeneity when located under

Acid-adapted cancer cells alkalinize their cytoplasm by degrading the acid-loading membrane transporter anion exchanger 2, SLC4A2

open access: yesCell Reports, 2023
Summary: Acidic environments reduce the intracellular pH (pHi) of most cells to levels that are sub-optimal for growth and cellular functions. Yet, cancers maintain an alkaline cytoplasm despite low extracellular pH (pHe).

Simultaneous quantification of ferrous gluconate and calcium gluconate in foods using liquid chromatography–tandem mass spectrometry (LC–MS/MS)

open access: yesApplied Biological Chemistry, 2023
Ferrous gluconate and calcium gluconate are used as food acidity regulators in South Korea, Japan, the European Union (EU), and other countries. A simultaneous analytical method was developed to quantify ferrous gluconate and calcium gluconate in food ...

Lewis Acidity Trend of Boron Trihalides: If Not π Back-Bonding, What Else? [PDF]

open access: yes, 2022
Lewis acidity trend of boron trihalides is a subject that has received a variety of explanations, and still the simple π back-bonding based one is believed by most, perhaps because of its simplicity, irrespective of opposing findings.

Bile acids as metabolic regulators [PDF]

open access: yesCurrent Opinion in Gastroenterology, 2015
This review focuses on the latest understanding of the molecular mechanisms underlying the complex interactions between intestine and liver bile acid signaling, gut microbiota, and their impact on whole-body lipid, glucose and energy metabolism.Hepatic bile acid synthesis is tightly regulated by the bile acid negative feedback mechanisms.

An Investigation of Mn−Ce−Based Conversion Coating on LZ91 Magnesium Alloy

open access: yesInternational Journal of Electrochemical Science, 2018
Most of the magnesium alloys are relatively reactive and tend to suffer corrosion. Consequently, surface modifications are performed to enhance the corrosion resistance and paint adhesion of the base magnesium alloys.

Regulation of Abscisic Acid Biosynthesis [PDF]

open access: yesPlant Physiology, 2003
Plant growth and development are regulated by internal signals and by external environmental conditions. One important regulator that coordinates growth and development with responses to the environment is the sesquiterpenoid hormone abscisic acid (ABA).
