Focal segmental glomerulosclerosis Actn4 mutation promotes podocyte detachment through maladaptation to periodic stretch.
ACTN4 is a transcriptional coactivator of NF-kappaB (show NFKB1 Proteins).
UCHL1 (show UCHL1 Proteins) upregulation in ACTN4-associated FSGS.
sLZIP negatively regulates skeletal muscle differentiation via interaction with ACTN4.
the C-terminal tail of alpha-actinin-4 is essential for its function in cell migration and adhesion to substratum.
Dexamethasone mey protect actin cytoskeleton stabilization from adriamycin-induced podocyte injury via alpha-actinin-4.
anti-dsDNA Fab (show FANCB Proteins) may enhance F-actin formation by the proprietary modification of alpha-actinin-4
Together, these results indicate that alpha-actinin (show ACTN1 Proteins) and the actin cytoskeleton are important components of the cisternal organelle that are probably required to stabilize the AIS (show AR Proteins).
Results suggest that ACTN4 is essential for maintaining normal spreading, motility, cellular and nuclear cross-sectional area, and contractility of lung fibroblasts by maintaining the balance between transcellular contractility and cell-adhesion.
newly developed mouse model of ACTN4-associated FSGS suggests a cause-and-effect relationship between actin cytoskeleton dysregulation by mutant alpha-actinin-4 and the deterioration of the nephrin (show NPHS1 Proteins)-supported slit diaphragm complex.
Data suggest that TYRO3 (show TYRO3 Proteins)-mediated phosphorylation of ACTN4 is involved in invasiveness of melanoma cells; TYRO3 (show TYRO3 Proteins)-mediated phosphorylation of ACTN4 requires FAK (show PTK2 Proteins) activation at tyrosine 397. (TYRO3 (show TYRO3 Proteins) = TYRO3 protein tyrosine kinase (show TYRO3 Proteins); ACTN4 = actinin alpha 4; FAK (show PTK2 Proteins) = focal adhesion kinase isoform FAK1 (show PTK2 Proteins))
ACTN4 knockdown resulted in the blockage of malignant cell proliferation, colony formation, and ameliorated metastasis potency. ACTN4-positive CSCs exhibited a higher ESA (show FLOT2 Proteins)(+) proportion, increased mammosphere-formation ability, and enhanced in vivo tumorigenesis ability.
These results demonstrate that both actinin (show ACTN1 Proteins)-1 and actinin-4 participate in the assembly of F-actin at invadopodia. Additionally, actinin-4 may have a selective advantage in accelerating invadopodia-mediated invasion of carcinoma cells.
Gene amplification of ACTN4 was a significant independent risk factor for death in patients with stage I/II oral tongue cancer (hazard ratio 6.08, 95% confidence interval 1.66-22.27). Gene amplification of ACTN4 is a potential prognostic biomarker for overall survival in oral tongue cancer.
ACTN4 knockdown near-completely abrogates both radioresistance and epithelial-mesenchymal transition-associated changes in breast cancer cells.
Fascin and alpha-actinin intrinsically segregate to discrete bundled domains that are specifically recognized by other actin-binding proteins.

High ACTN4 expression is associated with Lung Squamous Cell Carcinoma.
Our findings indicate that ACTN4 promotes EMT (show ITK Proteins) and tumorigenesis by regulating Snail (show SNAI1 Proteins) expression and the Akt (show AKT1 Proteins) pathway in cervical cancer. We propose a novel mechanism for EMT (show ITK Proteins) and tumorigenesis in cervical cancer.
Study found a functional Validation of an Alpha-Actinin-4 Mutation as a Potential Cause of an Aggressive Presentation of Adolescent Focal Segmental Glomerulosclerosis.
Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. In nonmuscle cells, the cytoskeletal isoform is found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. This gene encodes a nonmuscle, alpha actinin isoform which is concentrated in the cytoplasm, and thought to be involved in metastatic processes. Mutations in this gene have been associated with focal and segmental glomerulosclerosis.
