Human Oral Cancer Cell Interactions

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human oral squamous cell carcinoma cell lines Hep-2 and human lymphatic endothelial cells (hLECs) were obtained from BeNa Culture Collection (Hangzhou, Zhejiang, China). hLEC were cultured with 85% RPMI-1640 (Thermo Fisher Scientific, Waltham, MA, USA) and 15% FBS (Atlas Biologicals), and Hep-2 were maintained in RPMI-1640 (Thermo Fisher Scientific, Waltham, MA, USA) and 10% FBS at 37 °C in a humidified atmosphere containing 5% CO2.
The hLEC cells were plated in a six-well plate and treated with EBM-2 or Hep-2 conditioned medium for 48 h. Then the cells were collected and used to extract protein and RNA for correlation detection (western blot analysis and qRT-PCR).

Human laryngeal cancer cell lines TU177, Hep-2 were purchased from Bena Culture Collection (Beijing, China). All cells were cultured in Dulbecco’s Modified Eagle Medium (DMEM; Gibco, USA) with 10% Fetal Bovine Serum (FBS; Gibco, USA) at 37 °C and 5%CO2. The cells were transfected with prognosis related-lncRNA using Lipofectamine™ 3000 (Thermo Fisher Scientific, USA).

Establishment of Cisplatin-Resistant Hep-2 Cell Line

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human epithelial type 2 (Hep-2) was purchased from BeNa Culture Collection Co., Ltd. (Beijing, China), and the cells were cultured with Dulbecco's modified Eagle's medium (DMEM) including 10% fetal bovine serum (FBS) purchased from Procell Life Science&Technology Co., Ltd. (Wuhan, China). The cells were cultured at 37°C in a humidified incubator with 5% CO2. Trypsinase solution (0.25%) (HyClone Logan, State of Utah, USA) was used to obtain adherent cells. Hep-2 cells were cultured; the cells in the culture medium contained cisplatin to establish cisplatin-resistant cells. The concentration of cisplatin was gradually increased (0.5, 1, 1.5, and 2 μM). The cells were maintained in each concentration of cisplatin for a period of 3 months.

Comparative Analysis of LSCC Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Two LSCC cell lines (AMC-HN-8 and HEP-2) and the normal human bronchial epithelial cell (NHBEC) line were purchased from Bena Culture Collection. All the cell lines were cultured in Dulbecco's Modified Eagle Medium (DMEM) containing 10% fetal bovine serum. Twenty pairs of primary LSCC paraneoplastic and carcinoma tissues were pooled from Beijing Tiantan Hospital, Affiliated to Capital Medical University. All patients were pathologically confirmed, and fresh tissue was collected from them immediately after surgery and frozen in liquid nitrogen. Tissue collection was approved by the ethical review committee at Beijing Tiantan Hospital, Affiliated to Capital Medical University.

LSCC Cell Lines and Tissue Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Four LSCC cell lines (AMC-HN-8, HEP-2, TU-212 and TU-686) and the normal bronchial epithelial cell line NHBEC were purchased from Bena Culture Collection (Beijing, China). HEK293T cell line was purchased from American Type Culture Collection (ATCC) (Gaithersburg, MD, USA). All cell lines were cultured in DMEM medium (HyClone, Logan, Utah, USA) containing 10% fetal bovine serum (Biological Industries, Beit HaEmek, Israel) . Thirty pairs of primary LSCC paracancerous and cancerous tissues were collected from Chengde Central Hospital (Chengde, Hebei, China). All patients were pathologically confirmed, and the fresh tissues were immediately collected and frozen in liquid nitrogen after surgery. The collection of tissues was approved by the Review and Ethics committee of Chengde Central Hospital. Nuciferine (Purity, 99.49%) and other 49 natural products used in this study were all obtained from Selleck Chemicals (Houston, Texas, USA).

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.
