CAC1 knockdown increased sensitivity of LoVo/5-FU cells to 5-FU by influencing P-glycoprotein and MRP-1 expression.

open access: yes, 2019
(A) LoVo and LoVo/5-FU cells transfected with shCAC1 and shCON were subjected to FACS analysis with Annexin V-FITC and propidium iodide staining. (B) The expression of drug resistance-associated proteins, P-glycoprotein and MRP-1, in LoVo and LoVo/5-FU ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Combined Effect of 5-Fluorouracil and Acriflavine on Mortality Rate of Colorectal Cancer Cell Lines [PDF]

open access: yesMajallah-i dānishgāh-i ̒ulūm-i pizishkī-i Arāk, 2016
Background: A small percent of patients with colorectal cancer (CRC) respond to 5-Fluorouracil (5-FU), as a first line of chemotherapy. In this study in, in order to design a new chemotherapy protocol, the effect of 5-FU and acriflavine (ACF) cotreatment

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Enhanced 5-FU-mediated activation of p53-dependent nucleolar stress by MDM2/4 peptide inhibitors in colon cancer cells

open access: yes, 2022
Recent evidence suggest that the p53-dependent nucleolar stress induced by some anticancer drugs, such as 5-Fluorouracil (5-FU), might not be sufficient to produce cell cycle arrest and/or apoptosis, given the hyperactivation of MDM2 and MDM4, main ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

β-carotene plus 5-FU: a promising strategy to fight uL3-mediated drug resistance in colorectal cancer cells

open access: yes, 2022
The human ribosomal protein uL3 has been identified as a key sensor in the cell response to 5-FU in colorectal (CRC) cancer cells lacking p53. Specifically, uL3 downregulation is associated with 5-FU drug resistance, alteration in cell motility ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
