3,3'-Dihexyloxacarbocyanine (DiOC6(3)) is a lipophilic fluorescent dye with excitation/emission spectra of 484/501 nm, respectively.1 At high concentrations, DiOC6(3) accumulates in the endoplasmic reticulum (ER) and has been used to visualize ER in moss, yeast, and muscle cells. At low concentrations, DiOC6(3) accumulates in mitochondria and has been used to assess mitochondrial dislocations, fusion, and fission in living cells, as well as to visualize cellular apoptosis. DiOC6(3) can also be used to assess cell membrane potential, as depolarization directly correlates with increased fluorescence.2,3 DiOC6(3) photoexcitation inactivates intracellular organelle movement and inhibits microtubule polymerization in vitro.4

Nicotinamide improves in vitro lens regeneration in a mouse capsular bag model
Stem Cell Res Ther 2022 May 12;13(1):198.PMID:35550648DOI:10.1186/s13287-022-02862-8.
Background: Mammalian lens regeneration holds great potential as a cataract therapy. However, the mechanism of mammalian lens regeneration is unclear, and the methods for optimization remain in question. Methods: We developed an in vitro lens regeneration model using mouse capsular bag culture and improved the transparency of the regenerated lens using nicotinamide (NAM). We used D4476 and SSTC3 as a casein kinase 1A inhibitor and agonist, respectively. The expression of lens-specific markers was examined by real-time PCR, immunostaining, and western blotting. The structure of the in vitro regenerated lens was investigated using 3,3'-Dihexyloxacarbocyanine iodide \(DiOC6) and methylene blue staining, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL), and transmission electron microscopy. Results: The in vitro lens regeneration model was developed to mimic the process of in vivo mammalian lens regeneration in a mouse capsular bag culture. In the early stage, the remanent lens epithelial cells proliferated across the posterior capsule and differentiated into lens fiber cells (LFCs). The regenerated lenses appeared opaque after 28 days; however, NAM treatment effectively maintained the transparency of the regenerated lens. We demonstrated that NAM maintained lens epithelial cell survival, promoted the differentiation and regular cellular arrangement of LFCs, and reduced lens-related cell apoptosis. Mechanistically, NAM enhanced the differentiation and transparency of regenerative lenses partly by inhibiting casein kinase 1A activity. Conclusion: This study provides a new in vitro model for regeneration study and demonstrates the potential of NAM in in vitro mammalian lens regeneration.
Targeting the Wnt/beta-catenin pathway in renal cell carcinoma
Anticancer Res 2014 Aug;34(8):4101-8.PMID:25075035doi
Background/aim: Advanced renal cancer still has a very poor prognosis. In this regard recent investigations demonstrated a constitutive activation of the Wnt signaling pathway in renal cell carcinoma (RCC) thereby promoting an exaggerated cell proliferation. Especially, β-catenin overactivation and the functional loss of endogenous Wnt antagonists are associated with RCC carcinogenesis and progression. Thus, influencing Wnt signaling might represent a promising target in RCC treatment. Materials and methods: It was recently confirmed that ethacrynic acid (EA), ciclopirox olamine (CIC) and piroctone olamine (PO) can inhibit Wnt signaling in various cancer cell lines. Herein we investigated their cytotoxic potential towards human RCC cells and their influence on the Wnt pathway concerning apoptosis as determined by 3,3'-Dihexyloxacarbocyanine iodide \(DiOC6) and propidium iodide (PI) staining in flow cytometry and immunoblotting. Results: All three agents, EA, CIC and PO triggered a significant apoptotic activity in tested RCC cell lines in a time- and concentration-dependent manner. Moreover, exposure to CIC and PO decreased the expression of β-catenin as the pivotal feature within the canonical Wnt pathway. However, β-catenin expression increased upon the treatment with EA. Conclusion: These results reveal a significant selective induction of apoptosis by EA, CIC and PO and suggest a suppression of RCC survival in part due to inhibition of Wnt/β-catenin signaling. The development of targeted-therapies affecting the Wnt signaling pathway might therefore lead to novel treatment options for RCC patients.
Granulocytes without degranulation: neutrophil function in granule-depleted cytoplasts
Proc Natl Acad Sci U S A 1983 Aug;80(16):4968-72.PMID:6308664DOI:10.1073/pnas.80.16.4968.
Neutrophils respond to a variety of stimuli by generating superoxide anion, degranulating, and aggregating. Because it has been suggested that fusion of granules with the plasmalemma (degranulation) is necessary for aggregation and superoxide anion generation, we have tested whether these responses can be demonstrated in "neutrophilic cytoplasts" (granule-free vesicles of cytoplasm enclosed by plasmalemma). When examined by electron microscopy, cytoplasts were found to be approximately 4 microns in diameter and essentially granule free. Cytoplasts exposed to fMet-Leu-Phe (0.1 microM) generated superoxide anion after a lag of 16 sec but released no detectable beta-glucuronidase, lysozyme, or elastase. Aggregation of cytoplasts, as measured by changes in light transmission, was also activated by fMet-Leu-Phe; no lag period was observed. Electron microscopy of the aggregates demonstrated clusters of cytoplasts with a scalloped appearance. Superoxide anion generation and aggregation of cytoplasts were also activated by phorbol 12-myristate 13-acetate, concanavalin A, and leukotriene B4. Exposure of cytoplasts to the dye 3,3'-Dihexyloxacarbocyanine iodide \(DiOC6(3)] led to dye uptake and enhancement of fluorescence, implying that the vesicles were sealed and maintained a membrane potential across the plasmalemma. Exposure of DiOC6(3)-loaded cytoplasts to fMet-Leu-Phe and PMA caused a rapid loss of dye fluorescence that was not inhibited by CN-, compatible with their lack of mitochondria. Exposure of dye-loaded cytoplasts to concanavalin A or leukotriene B4 caused an increase in fluorescence--i.e., a hyperpolarization. These results demonstrate that degranulation is not a prerequisite for aggregation or superoxide anion generation. The retention of ionic gradients and changes in membrane potential, as measured by DiOC6(3) fluorescence changes, suggest a fundamental role for ionic movements in activating superoxide anion generation and aggregation.
Mitochondrial alterations induced by 532 nm laser irradiation
Gen Physiol Biophys 2005 Jun;24(2):209-20.PMID:16118473doi
Mitochondrial alterations were monitored after low power green laser (532 nm, 30 mW) irradiation in the case of whole cells (B-14) and isolated mitochondria (from Wistar rat heart). 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium-bromide (MTT) assay products were significantly higher (by 8%) in irradiated B-14 cells as compared to non-irradiated controls. Mitochondrial transmembrane potential of B-14 cells, measured by means of a fluorescent probe 3,3'-Dihexyloxacarbocyanine iodide \(DiOC6(3)), significantly increased (by 13%) after exposure to green laser irradiation. Another MTT assay was used for isolated mitochondria suspensions in order to examine the effect of green laser irradiation on stimulation of processes related to oxidative phosphorylation. It revealed 31.3%-increase in MTT assay products in irradiated mitochondria as compared to controls. Laser irradiation of isolated mitochondria suspension did not significantly change 1,6-diphenyl-1,3,5-hexatriene (DPH) fluorescence anisotropy, indicating that mitochondrial membrane fluidity was not affected by laser light. Fluorescence emission spectra of irradiated as well as non-irradiated mitochondria suspensions showed fluorescence maximum at 635 nm, corresponding to emission of Protoporphyrin IX, which was significantly lower (by 20.7%) in irradiated sample.
Kinesin-mediated organelle translocation revealed by specific cellular manipulations
J Cell Biol 1994 Nov;127(4):1021-39.PMID:7962067DOI:10.1083/jcb.127.4.1021.
The distribution of membrane-bound organelles was studied in cultured hippocampal neurons after antisense oligonucleotide suppression of the kinesin-heavy chain (KHC). We observed reduced 3,3'-Dihexyloxacarbocyanine iodide \(DiOC6(3)) fluorescent staining in neurites and growth cones. In astrocytes, KHC suppression results in the disappearance of the DiOC6(3)-positive reticular network from the cell periphery, and a parallel accumulation of label within the cell center. On the other hand, mitochondria microtubules and microfilaments display a distribution that closely resembles that observed in control cells. KHC suppression of neurons and astrocytes completely inhibited the Brefeldin A-induced spreading and tubulation of the Golgi-associated structure enriched in mannose-6-phosphate receptors. In addition, KHC suppression prevents the low pH-induced anterograde redistribution of late endocytic structures. Taken collectively, these observations suggest that in living neurons, kinesin mediates the anterograde transport of tubulovesicular structures originated in the central vacuolar system (e.g., the endoplasmic reticulum) and that the regulation of kinesin-membrane interactions may be of key importance for determining the intracellular distribution of selected organelles.
