Transcription regulation of chemokine receptor CXCR4 by nuclear respiratory factor 1 (NRF1) controls estrogen-induced malignant transformation of breast epithelial cells to breast cancer stem cells
AACR Annual Meeting 2016
J. K. Das and D. Roy
Chemokine receptor CXCR4 is involved in the maintenance of stemness property of stem cells, aging and metastasis of cancer. NRF1 is one of the major transcription factors that controls transcription of CXCR4. In this study, the authors have investigated whether transcription regulation of CXCR4 by NRF1 controls estrogen-induced malignant transformation of breast epithelial cells to breast cancer stem cells.

Shielding of the Geomagnetic Field Alters Actin Assembly and Inhibits Cell Motility in Human Neuroblastoma Cells
Scientific Reports 2016
W-C. Mo, Z-J. Zhang, D-L. Wang, Y. Liu, P. Bartlett and R-Q. He
Earth’s magnetic field is a natural part of our environment. Using HoloMonitor M4, the authors show that the elimination of Earth’s magnetic field affects cell behavior. According to the authors, the findings suggest that magnetic field elimination may be used to prevent tumor progression in future clinical applications. The findings also provide clues to which health risks astronauts are exposed to during deep space explorations, where no magnetic field is present.

Pseudomonas aeruginosa N-3-oxo-dodecanoyl-homoserine Lactone Elicits Changes in Cell Volume, Morphology, and AQP9 Characteristics in Macrophages
Frontiers in Cellular and Infection Microbiology 2016
A. Holm, K-E. Magnusson and E. Vikström

Pseudomonas aeruginosa is one of the antibiotic resistant bacteria types that cause hospital-acquired infections. In combination with other imaging techniques, the authors used HoloMonitor M4 to study how these bacteria interact with the immune system.

Pseudomonas aeruginosa infection is a serious problem in patients hospitalized with cancer, cystic fibrosis and burns. The case fatality rate in these patients is exceedingly high. Research for the discovery of new antibiotics and drugs against P. aeruginosa is therefore very much needed.

The Curcumin Analog C-150, Influencing NF-κB, UPR and Akt/Notch Pathways Has Potent Anticancer Activity In Vitro and In Vivo
L. Hackler et al.
Holographic microscopic analysis of C-150 induced cell death using HoloMonitor M3

C-150 – a Mannich-type curcumin derivative – exhibited pronounced cytotoxic effects against eight glioma cell lines at micromolar concentrations. Inhibition of cell pro­lifera­tion by C-150 was mediated by affecting multiple targets as confirmed at transcription and protein level. C-150 effectively reduced the transcription activation of NFkB, inhibited PKC-alpha which are constitutively over-expressed in glioblastoma.

Glioblastoma is the most common and most aggressive cancer originating within the brain.

From immobilized cells to motile cells on a bed-of-nails: effects of vertical nanowire array density on cell behavior
Scientific Reports 2015
H. Persson, Z. Li, J. O. Tegenfeldt, S. Oredsson and C. N. Prinz

During recent years, vertical nanowire arrays have received increasing atten­tion for their possible use in life sciences, as electrodes, biosensors, as well as for axonal guidance, cell injections and anti-bacterial proper­ties. The rapidly expanding number of nanowire applications calls for a better under­standing of the inter­actions between cells and nanowires.

Using HoloMonitor the researchers investigated the effects of nanowire density on cell movement, division and morphology. The results provide guidelines to minimize cellular stress on nanowire arrays. Additionally, the findings show that cell behavior can be controlled by adjusting nanowire density, which may have applications in drug development.

Enhanced Cytotoxicity of Folic Acid-Targeted Liposomes Co-Loaded with C6 Ceramide and Doxorubicin: In Vitro Evaluation on HeLa, A2780-ADR and H69-AR Cells
Molecular Pharmaceutics 2015
S. K. Sriraman, J. Pan, C. Sarisozen, E. Luther and V. Torchilin
Article figure show showing drop in cell volume

Current research in cancer therapy is shifting towards the use of combinational drug-treatment regimens. However, the efficient delivery of drug combinations is governed by a number of complex factors in the clinical setting.

The development of a novel folic acid-targeted liposomal formulation, simultaneously co-loaded with C6 ceramide and doxorubicin is reported. FA-(C6+Dox)-LP were able to significantly enhance the induction of apoptotic events in HeLa cell mono­layers as compared to the other treatment groups.

Using HoloMonitor M4, it was found that FA-(C6+Dox)-LP treated HeLa cells underwent rapid progression to apoptosis (cell suicide) after 21 hours, as evidenced by a drastic drop in cell area after loss of cell membrane integrity.

Water homeostasis in infection and inflammation – Quorum sensing AQP9
ASCB Annual Meeting 2015
A. Holm, K-E. Magnusson and E. Vikström
Poster Image: Representative images of the time-lapse sequence used to quantify cell volume after treatment

Macrophages are an important part of the immune system. They are activated by molecules produced by infecting bacteria. Activation induces macrophages to elevate their membrane content through water specific gates. These aquaporins allow water to enter the cells and make them swell.

This poster by researchers at Linköping University in Sweden shows this increase of aquaporins after acti­vation by bacterial molecules. Using Holo­Monitor M4, morphology analysis of activated macrophages visualizes and quantifies the increase of cell volume, following the increased number of aquaporins in the cell membrane.

Targeted tumor therapy by Rubia tinctorum L.: analytical character­ization of hydroxyan­thraquinones and investigation of their selective cytotoxic, adhesion and migration modulator effects on melanoma cell lines
Cancer Cell International 2015
E. Lajkó, P. Bányai, Z. Zámbó, L. Kursinszki, É. Szőke and L. Kőhidai

The effects of alizarin, purpurin and an aqueous extract from transformed hairy root culture of Rubia tinctorum L. were examined on (1) cell proliferation, (2) apoptosis, (3) cell adhesion/morphology and (4) migration (chemotaxis, chemokinesis) of human melanoma cell lines (A2058, HT168-M1) and human fibroblast cells (MRC-5), as well as (5) the aqueous extract was analytically characterized.

All tested substances elicited chemo­repellent effect in melanoma cells (malignant skin cancer cells), while in MRC-5 fibroblasts, only the alizarin exhibited such a repellent character. Indices of chemo­kinesis measured by Holo­Monitor M4 (migration, migration directness, motility and motility speed) were signifi­cantly enhanced by alizarin and purpurin as well, while morphometric changes were weak in the two melanoma cell lines.

Comparison of the effects of pharmaceutical compounds on tumor cells in 2D and 3D in vitro models using label-free, quantitative 4 dimensional holographic imaging
AACR-NCI-EORTC Inter. Conf. on Molecular Targets and Cancer Therapeutics 2015
E. Luther, G. Salzano, S. K. Sriraman, D. Costa and V. P. Torchilin
Poster Image: As the complexity of the formulations increases, there is a decrease in the high optical thickness and a corre­spond­ing increase in the low optical thick­ness consistent with increasing cell death.
We developed a novel 4D holographic imaging method using Holo­Monitor M4 and Image J. Here, we present methods for comparing traditional 2D and 3D in vitro models. Our example of HT1080 cells treated with dox clearly shows the superiority of the 3D model, an important step in developing assays that better emulate multi-dimensional biological processes and offer the possibility of evaluating effects of drugs at lower cost and experimental complexity than those of in vivo assays.

Characterization of macrophage behavior by 4-dimensional label free quantitative holographic imaging
AACR Annual Meeting 2015
Ed Luther, Meghna Talekar, Adwait Oka, Qijun Ouyang and Mansoor Amiji
The tumor microenvironment consists of several cell types including cancer cells and stromal cells (fibroblasts and inflammatory cells) embedded in extracellular matrix. Among the inflammatory cells, macrophages are critical mediators of tumorigenesis. Their behavior and activation is controlled by a large number of chemo-stimulants, and are broadly classified into two polarization groups, M1 (classically activated macro­phages), that enable the release of cytokines and chemokines that induce tumor suppression and M2 (alternatively activated macrophages), that induce tissue repair and angiogenesis. In the tumor micro­environ­ment this translates into tumor promotion. We employed a newly developed label free holographic time lapse imaging system to characterize the morphology and motility of macrophages in response to stimulants and tumor cells in 4-dimensional models of the tumor microenvironment.

Edaravone Protects against Methylglyoxal-Induced Barrier Damage in Human Brain Endothelial Cells
Andrea E. Tóth et al
Read application note…
The authors use HoloMonitor M3 to study morphological alterations induced in human brain endothelial cells (hCMEC/D3) by treatment with methylglyoxal and co-treatment with edaravone for 4 hours. Methylglyoxal triggers carbonyl stress and activates a series of inflammatory responses leading to accelerated vascular damage. Edaravone is the active substance of a Japanese medicine, which aids neurological recovery following acute brain ischemia and subsequent cerebral infarction. The aim of the study was to test whether edaravone can exert a protective effect on the barrier properties of human brain endothelial cells (hCMEC/D3 cell line) treated with methylglyoxal.

HAMLET Binding to α-Actinin Facilitates Tumor Cell Detachment
M. Trulsson, H. Yu, L. Gisselsson, Y. Chao, A. Urbano, S. Aits, A-K. Mossberg, C. Svanborg
Trulsson et al. used the label-free cell morphology analysis capabilities of the HoloMonitor to follow the cell death process of A549 lung cancer cells treated with HAMLET (right). HAMLET is a milk protein-lipid complex which is both tumoricidal and triggers cell detachment both in vivo and in vitro. HAMLET treatment therefore caused cells to round up and become less optically dense, which was clearly quantified by the HoloMonitor.

Holographic time-lapse series showing a tripolar metaphase (green broken lines; t = 0) followed by tripolar ana-telophase (t = 14–36 min). Cytokinesis is initiated along two cleavage furrows in this cell division (t = 70 min), but one of the cleavage furrows regresses and only two daughter cells are formed (t = 306 min), of which the larger is binucleate as evidenced by two clusters of nucleoli. The larger cell (t = 3,192 min) enters mitosis (red broken lines), forming a single mitotic plate and divides into two daughters (t = 3,586 min). Daughter cells from both cell divisions remained without evidence of cell death or degeneration throughout the observation time.
