We originally purchased SW620, HT29 cell lines of human colon cancer and MC38 murine colon cancer cell line, which will be utilized in following experiments, from the American Type Culture Collection (Manassas, VA), and the cells were cultivated in DMEM medium according to the Defense Technical Information Center recommendation (DTIC) in addition of 10% fetal bovine serum (FBS, Gibico, Life Technology, Austria), 1% penicillin/streptomycin (PS) in a humidified 5% (v/v) atmosphere of CO2 at 37 °C.

Corn oil (Mazola, ACH Food Companies Inc., Memphis, TN) was purchased from a local market. β-carotene (synthetic, ≥93% (UV), powder) was sourced from Sigma-Aldrich (Ireland).
Lecithin was obtained from Alfa Aesar (Karlsruhe, Germany). Sodium caseinate (NaCas) (≥92% purity) was from Acros Organics (Geel, Belgium). The Caco-2 cell line was purchased from the European Collection of Cell Cultures (ECACC 86010202) and the human monocyte THP-1 (ATCCTIB-202) and the human colon adenocarcinoma HT-29 cell lines (ATCCHTB-38) were purchased from American Type Culture Collection. This latter cell line was differentiated to HT-29-MTX following the protocol described by Guri et al. (2013) . Tissue culture plastics were sourced from Sarstedt Ltd. (Wexford, Ireland). CellTiter 96 AQueus One Solution reagent was purchased from Promega (MyBio, Kilkenny, Ireland). Milli-Q water was used to prepare all nanoemulsions. All other chemicals were sourced from Sigma-Aldrich (Ireland) unless specified otherwise.

HT-29 Cell Culture Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
The HT-29 cell lines used in this work were obtained from the American Type Culture Collection (Rockville, MD) and were cultured at 37°C under 5% CO2 in RPMI 1640 medium supplemented with antibiotics (100 U/ml of penicillin and 100μg/ml of streptomycin) and 10% heat-inactivated fetal bovine serum. After the cells had grown to confluence, they were replated onto 12-mm round coverslips (Warner Instruments Inc., Hamden, CT) and incubated for at least 24 h before use for cytosolic Ca2+ concentration([Ca2+]cyt).

Curcumin Modulates Transcriptional Profiles

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human hepatocellular carcinoma HepG2 and human colorectal cancer HT29 cell lines (American Type Culture Collection [ATCC], Rockville, MD, USA) were treated in triplicate with 20 μM of curcumin dissolved in dimethyl sulfoxide. These samples were then submitted to Genometry, Inc. (Cambridge, MA, USA) for L1000 microarray profiling. The microarray gene expression profiling results were classified according to the up- and down-regulated gene signatures, which were subsequently used to query the C-Map [3 (link)] and CLUE [4 (link)] databases for analysis of the gene expression of curcumin. Additional details are listed in Supplementary materials.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
