Intracellular Fragmentation of Bone Resorption Products by Reactive Oxygen Species Generated by Osteoclastic Tartrate-resistant Acid Phosphatase*

open access: yesJournal of Biological Chemistry, 1999
Tartrate-resistant acid phosphatase (TRAP) is highly expressed in bone-resorbing osteoclasts and activated macrophages. It has been suggested that a redox-active iron in the binuclear iron center of TRAP could have the capacity to react with hydrogen ...

Berberine–cinnamic acid co‐crystal effect in ameliorating hyperlipidemia might be regulated through the PI3K/AKT/mTOR/SREBP‐1 signaling pathway

open access: yesFEBS Open Bio, EarlyView.
Berberine–cinnamic acid co‐crystal (BBR‐CA) inhibits the phosphorylation of the phosphatidylinositol 3‐kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway, suppressing the transfer of pre‐sterol regulatory element‐binding proteins‐1 (SREBP‐1) from the endoplasmic reticulum to the nucleus. This results in a decrease in the expression level of

Actividad de las fosfatasas ácidas y alcalinas (extracelulares e intracelulares) en hongos de la rizosfera de Arachis hypogaea (Papiloneaceae)

open access: yesRevista de Biología Tropical, 2004
El papel potencial de los hongos aislados de la rizosfera del maní, en la producción de fosfatasas ácidas y alcalinas extracelulares e intracelulares, fue evaluado in vitro. Las fosfatasas ácidas y alcalinas extracelulares, mostraron la mayor actividad y

Phosphatidylinositol (4,5)-bisphosphate turnover by INP51 regulates the cell wall integrity pathway in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2004
Signal transduction pathways are important for the cell to transduce external or internal stimuli where second messengers play an important role as mediators of the stimuli. One important group of second messengers are the phosphoinositide family present

Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.

Measurement of Acid Ecto-phosphatase Activity in Live Leishmania donovani Parasites

open access: yesBio-Protocol, 2019
Acid ecto-phosphatases are enzymes that hydrolyze phosphomonoesters in the acidic pH range with their active sites facing the extacellular medium. Their activities can be measured in living cells.

Cluster Analysis of Ranunculus Species [PDF]

open access: yes, 2002
The aim of the experiment was to examine whether the morphological characters of eleven species of Ranunculus collected from a number of populations were in agreement with the genetic data (isozyme).

Short‐term actions of epigalocatechin‐3‐gallate in the liver: a mechanistic insight into hypoglycemic and potential toxic effects

open access: yesFEBS Open Bio, EarlyView.
Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...
