Gene expression profile of two colorectal cancer HT29 and DLD-1 cell lines cultivated in 2-dimensional or 3-dimensional cell culture enriched with laminin rich extracellular matrix proteins

ABSTRACT: Conventional monolayer cell cultures used in cancer research accumulated basic knowledge of carcinogenesis which correlates with basic observations in tumor biology. Nevertheless, attempts to transfer accumulated cancer biology knowledge to clinical applications fails in most of the cases. Gathered data suggest that 2D cell culture models lack many features of tumor tissue in vivo. Although it has been demonstrated that cancer cells are generally more resistant to various types of treatments when cultured in extracellular matrix (ECM) based 3D cultures it is not clear if this phenomenon is attributed to the ECM dependent gain of function or the loss of non-physiological cellular state demonstrated while cultured at 2D conditions. To address the question of which universal molecular mechanisms if any are gained/lost in ECM-dependent manner we carried out genome wide gene expression analysis of human colorectal carcinoma DLD-1 and HT-29 cell lines cultured in 2D or ECM based 3D conditions.

Gene expression profile of mouse Lewis lung carcinoma cell line cultivated in 2-dimensional or 3-dimensional cell culture enriched with laminin rich extracellular matrix proteins.

Project description:Obvious advantages of 3D cell culture model are the cell morphology better reflecting tissue cell morphology, the formation of zones of i) active proliferation, ii) quiescent viable cell zone and iii) necrotic zone, as well as formation of nutrition, oxygen and drug gradients better reflecting cellular environment in tissue. Nevertheless the 3D cultures are a model still not resembling full complexity of tumor tissue environment in vivo. Few obvious limitations of 3D cell cultures as cancer research model are the lack of vasculature, host immune response and other cell-cell interactions that occur between cancer and stromal cells in tumors. Recognized advantages and limitations of the 3D cell culture models, however do not suggest directly the areas of cancer biology where 3D models could be applied with highest success. Hence detailed analysis at the molecular level of 2D/3D cell cultures and tumors in vivo are needed to unlock the power of 3D cell culture model. In order to elucidate which biological pathways of cancer cells in tumors are best resembled by the 3D cell culture model we have analyzed whole genome gene expression changes in mouse LLC1 cell line when cultured in 2D or laminin rich ECM 3D system. RNA was isolated 48h after growing in two different cell culture systems.

Gene expression profile of two colorectal cancer HT29 and DLD-1 cell lines treated with single or fractionated ionizing radiation doses under 3D cell culture conditions.

Project description:Tumor cell response to irradiation also depends on their microenvironment. Therefore ongoing investigation of three-dimensional (3D) cell culture models provide researchers with essential data studying and remodeling radiotherapeutic implications in cancer treatment. 3D culture models were shown to mimic in vivo cell microenvironment more accurately than the standard two-dimensional cell monolayer (2D) cultures. Growing evidence suggests that 2D and 3D cultured cell gene expression pattern discrepancies following irradiation is highly dependent on cell-ECM interactions. It has been shown that laminin-rich-extracellular matrix (lr-ECM) used in 3D cultures not only alters cancer cell phenotype and response to external stimuli but also affects their differentiation, migration and survivability. Thus, a change in these fundamental cell properties demands us to reconsider data previously collected using 2D in vitro models. RNA was harvested from two colorectal cancer cell lines cultivated under 3D cell culture conditions, 4h after treatment of single (2 Gy or 10 Gy) or fractionated (5x2 Gy) ionizing radiation dose.

Gene expression analysis of MCF7 breast cancer cells cultured as xenografts, in two dimensional cultures, in polyHEMA anchorage independent three dimansional cell culture models and in Matrigel three dimensional cultures.

Project description:The traditional method for studying cancer in vitro is to grow immortalized cancer cells in two-dimensional (2D) monolayers on plastic. However, many cellular features are impaired in these unnatural conditions and big alterations in gene expression in comparison to tumors have been reported. Three-dimensional (3D) cell culture models have become increasingly popular and are suggested to be better models than 2D monolayers due to improved cell-to-cell contacts and structures that resemble in vivo architecture. The aim of this study was to compare gene expression patterns of MCF7 breast cancer cells when grown as xenografts, in 2D, in polyHEMA coated anchorage independent 3D models and in Matrigel on-top 3D cell culture models. Surprisingly small variations in gene expression patterns were observed between the models indicating that 3D and xenograft are not always that different from 2D cell cultures. Gene expression analysis of MCF7 breast cancer cells cultured as xenografts for 43 days, in two dimensional cultures for seven days (2D7d), in polyHEMA three dimensional cell culture models for four and seven days (PH7d and PH7d), and in Matrigel three dimensional cultures for four and seven days (MG4d and MG7d). Two biological replicates was included for each sample.

Madin-Darby Canine Kidney (MDCK) cells grown in 2-dimensional and 3-dimensional type I collagen culture.

Project description:In order to gain insight into epithelial morphogenesis and the influence of culture geometry on gene expression patterns, Madin Darby Canine Kidney (MDCK) epithelial cells where grown in 2-dimensional (2D) culture or 3-dimensional (3D) culture . MDCK cells cultured in 2D were plated atop a pre-solidified type I collagen gel. Cells cultured under these conditions grew as flat monolayer sheets. In 3D culture, cells are embedded within type I collagen gel. Cells grown under these conditions form large spherical cysts with hollow central lumens. We anticipate, therefore, that these results provide insight into the mechanisms that regulate epithelial cystogenesis. Cells grown in the 2D or 3D geometries were collected from digested type I collagen gels on day 8. The 2D MDCK cells were treated as the control condition and there gene expression patterns were compared to those of 3D grown cells, which served as the experimental condition.

Organotypic three-dimensional cancer cell cultures mirror drug responses in vivo: Lessons learned from the inhibition of EGFR signaling

Project description:Complex three-dimensional (3D) in vitro model systems that recapitulate human tumor biology are essential to better understand the pathophysiology of the disease and to aid in the discovery of novel anti-cancer therapies. 3D organotypic cultures exhibit intercellula communication, nutrient and oxygen gradients, and cell polarity that is lacking in traditional two-dimensional (2D) monolayer cultures. In the present study, we could demonstrate that 2D and 3D cancer models exhibit different drug sensitivities towards both targeted inhibitors of EGFR signaling and broad acting cytotoxic agents. Changes in the kinase activities of Erb family members and differential expression of apoptosis- and survival-associated genes before and after drug treatment may account for the differential drug sensitivities. Importantly, EGFR oncoprotein addiction was evident only in the 3D cultures mirroring the effect of EGFR inhibition in the clinic. Furthermore, targeted drug efficacy was strongly increased when incorporating cancer-associated fibroblasts into the 3D cultures. Taken together, we could provide conclusive evidence that complex 3D cultures are more predictive of the clinical outcome than their 2D counterparts. In the future, 3D cultures will be instrumental for understanding the mode of action of drugs, identifying genotype-drug response relationships and developing patient-specific and personalized cancer treatments.

Three-dimensional tumor cell growth stimulates autophagic flux and recapitulates chemotherapy resistance

Project description:Current preclinical models in tumor biology are limited in their ability to recapitulate relevant (patho-) physiological processes, including autophagy. Three-dimensional (3D) growth cultures have frequently been proposed to overcome the lack of correlation between two-dimensional (2D) monolayer cell cultures and human tumors in preclinical drug testing. Besides 3D growth, it is also advantageous to simulate shear stress, compound flux and removal of metabolites, e.g. via bioreactor systems, through which culture medium is constantly pumped at a flow rate reflecting physiological conditions. Here, we show that both Staticic 3D growth and 3D growth within a bioreactor system modulate key hallmarks of cancer cells, including proliferation and cell death as well as macroautophagy, a recycling pathway often activated by highly proliferative tumors to cope with metabolic stress. The autophagy-related gene expression profiles of 2D- and 3D-grown cells are substantially different, with the 3D-grown cells exhibiting an expression profile closely resembling the (patho-) physiological Statice of a tumor. Underscoring the importance of this pathway, autophagy-controlling transcription factors, such as TFEB and FOXO3, are upregulated in tumors, and 3D-grown cells have increased expression compared with cells grown in 2D conditions. Three-dimensional cultures depleted of the autophagy mediators BECN1, ATG5 or ATG7 or the transcription factor FOXO3, are more sensitive to cytotoxic treatment. Accordingly, combining cytotoxic treatment with compounds affecting late autophagic flux, such as chloroquine, renders the 3D-grown cells more susceptible to therapy and increases intracellular doxorubicin concentration to the level of 2D-grown cells. Altogether, 3D cultures are a valuable tool to study drug response of tumor cells, as these models recapitulate (patho-) physiologically relevant pathways, such as autophagy.

3D Culture of human lung fibroblasts decreases proliferative and increases extracellular matrix remodeling genes

Project description:Fibroblasts are the main producers of extracellular matrix (ECM) responsible for ECM maintenance and repair, a process often disrupted in chronic lung diseases. The accompanying mechanical changes adversely affect resident cells and overall lung function. Numerous models have been used to elucidate fibroblast behavior which are now evolving towards complex 3D models incorporating ECM, aiming to replicate the cells’ native environment. Little is known about the cellular changes that occur when moving from 2D to 3D cell culture. This study compared gene expression profiles of primary human lung fibroblasts from 7 subjects with normal lung function, cultured for 24 hours on 2D collagen I-coated tissue culture plastic and in 3D collagen I hydrogels, which are commonly used to mimic ECM in various models, from contraction assays to organ-on-a-chip models. Comparing 3D to 2D cell culture, 6,771 differentially expressed genes (2,896 up, 3,875 down) were found; enriched gene sets within the downregulated genes, identified through Gene Set Enrichment Analysis and Ingenuity pathway analysis, were involved in the initiation of DNA replication which implied downregulation of fibroblast proliferation in 3D. Observation of cells for 72 hours in 2D and 3D environments confirmed the reduced progression through the cell cycle in 3D. A focused analysis examining the Hippo pathway and ECM-associated genes, showed differential patterns of gene expression in the 3D versus 2D culture. Altogether, the transcriptional response of fibroblasts cultured in 3D indicated inhibition of proliferation, and alterations in Hippo and ECM pathways indicating a complete switch from proliferation to ECM remodeling.
