Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Principal non-singularity of Fourier matrices on Zp×Zq ${\mathbb{Z}}_{p}{\times}{\mathbb{Z}}_{q}$ and Z2k×Zq ${\mathbb{Z}}_{2}^{k}{\times}{\mathbb{Z}}_{q}$

Demonstratio Mathematica
Let F n be the n × n Fourier matrix on the cyclic group Zn ${\mathbb{Z}}_{n}$ , a renowned theorem of Chebotarëv asserts that all minors in F n for prime n are non-zero.

Permutability graph of cyclic subgroups

, 2015
Let $G$ be a group. \textit{The permutability graph of cyclic subgroups of $G$}, denoted by $Γ_c(G)$, is a graph with all the proper cyclic subgroups of $G$ as its vertices and two distinct vertices in $Γ_c(G)$ are adjacent if and only if the corresponding subgroups permute in $G$.

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

a linear in-situ algorithm for the power of cyclic permutation [PDF]

, 2008
Natl. Univ. Defense Technology, School of Computer ScienceWe present and develop a linear in-situ algorithm for the power of a cyclic permutation Pr(-n< r < n). Several related algorithms become the special cases of this algorithm.

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Quasi-cyclic extension based on PEG algorithm for construction of LDPC codes

Tongxin xuebao, 2008
Several important relations between the cycle structure on the Tanner graph and the parity-check matrix H of LDPC codes were proved.A new algorithm for constructing LDPC codes was proposed that introduced quasi-cyclic ex-tension method to PEG algorithm ...

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for
