Effect of Langmuir monolayer of bovine serum albumin protein on the morphology of calcium carbonate [PDF]

open access: yesMaterials Science and Engineering: C, Volume 29, Issue 6, 1 August 2009, Pages 1998-2002, 2011
Bovine serum albumin (BSA) Langmuir monolayer, as a model of biomineralization-associated proteins, was used to study its effect on regulated biomineralization of calcium carbonate. The effects of the BSA Langmuir monolayer and the concentration of the subphase solution on the nucleation and growth processes and morphology of the calcium carbonate ...

Purification and characterization of a thermophilic NAD+‐dependent lactate dehydrogenase from Moorella thermoacetica

open access: yesFEBS Open Bio, EarlyView.
The thermophilic acetogenic model organism Moorella thermoacetica can utilize lactate as substrate. The formation of lactate by reduction of pyruvate is energetically favorable, but the reverse reaction, the oxidation of lactate to pyruvate with NAD+ as electron acceptor is challenging.

Reclamation of filtered bicarbonate

open access: yesKidney International, 1990
Approximately 85% of the filtered bicarbonate load is reabsorbed in the proximal convoluted tubule. Transport in this segment displays saturation kinetics, and exhibits a higher capacity for reabsorption in the earliest portion. Reclamation of bicarbonate is highly regulated in the proximal tubule: an increase in luminal [HCO3-], flow rate and arterial

DABs accumulate bicarbonate

open access: yesNature Microbiology, 2019
A newly discovered energy-linked carbonic anhydrase, DabBA2, is a two-protein complex responsible for inorganic carbon accumulation in the sulfur bacterium Halothiobacillus neapolitanus. DABs are present in a wide range of proteobacterial clades, suggesting that they function in diverse metabolic pathways.

FAM136A depletion induces mitochondrial stress and reduces mitochondrial membrane potential and ATP production

open access: yesFEBS Open Bio, EarlyView.
FAM136A depletion upregulated ROS production, reduced mitochondrial membrane potential (ΔΨ) and ATP production, and upregulated expression of PCK1, PCK2, HMGCS1, and HMGCS2. The expression of both TOMM22 and TOMM20 was also upregulated. FAM136A depletion reduced HCCS that produce holocytochrome c by combining heme to apocytochrome c, and reduced the ...

Bicarbonate in cystic fibrosis [PDF]

open access: yesJournal of Cystic Fibrosis, 2017
Cystic fibrosis (CF, mucoviscidosis) is caused by mutations in the gene encoding CF transmembrane conductance regulator (CFTR), which is a chloride and bicarbonate channel necessary for fluid secretion and extracellular alkalization. For a long time, research concentrated on abnormal Cl- and Na+ transport, but neglected bicarbonate as a crucial factor ...

Mapping Hsp104 interactions using cross‐linking mass spectrometry

open access: yesFEBS Open Bio, EarlyView.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

A non‐fluorescent immunohistochemistry method for measuring autophagy flux using MAP1LC3/LC3 and SQSTM1 as core markers

open access: yesFEBS Open Bio, EarlyView.
We introduce an immunohistochemistry method to measure autophagy flux, highlighting the active degradation and recycling of cellular waste. This cost‐effective approach uses tissue samples to track key markers like LC3 and SQSTM1, revealing how cells maintain health or respond to diseases such as cancer. It bridges the gap between research and clinical

Downregulation of O‐GlcNAcylation enhances etoposide‐induced p53‐mediated apoptosis in HepG2 human liver cancer cells

open access: yesFEBS Open Bio, EarlyView.
Etoposide, a topoisomerase II inhibitor, reduces O‐GlcNAcylation in HepG2 liver cancer cells. Further inhibition of O‐GlcNAc transferase by OSMI‐1 enhanced etoposide‐induced apoptosis, lowering the IC50 for viability and increasing the EC50 for cytotoxicity.
