Chemicals including cholesteryl oleate, glyceryl trioleate, and simvastatin were purchased from Sigma-Aldrich. Avasimibe used in vitro and in vivo studies were purchased from Selleckchem.com. Human low-density lipoprotein (LDL) was purchased from Creative Laboratory Products (Indianapolis, IN) and conjugated with DiI by the authors. Lipoprotein-deficient Serum (LPDS) was purchased from Biomedical Technologies (Ward Hill, MA).
Aspc 1
The AsPC-1 is a laboratory equipment product. It is a cell line derived from a human pancreatic adenocarcinoma. The core function of the AsPC-1 is to serve as a model system for cancer research and related applications.

Pancreatic Cell Line Cultivation and Lipid Assay
Pancreatic Cancer Cell Line Characterization
The two PDAC lines, PANC1 and AsPC1, both resemble the majority genotype of pancreatic cancers in having activated KRAS and mutant p53 [56 (link)]. Moreover, CDKN2A is epigenetically down-regulated in both cell lines [57 (link), 58 (link)]. The CPI-613-resistant member of this pair, AsPC1, was isolated from a post-treatment metastasis [59 (link)]; whereas, CPI-613-sensitive PANC1 was isolated from an untreated primary tumor [56 (link), 60 (link)]. AsPC1 displays SMAD4 loss, as do the majority of clinical PDACs (whereas PANC1 retains SMAD4 expression) [61 (link)]. Collectively, these features are consistent with AsPC1 being a useful model for difficult-to-treat clinical PDAC cases more generally.
Culturing Human Pancreatic Cell Lines
Pancreatic Cancer Cell Line Manipulation
PANC-1 and AsPC-1 cells were used to silence or overexpress ITGBL1. For ITGBL1 downregulation, PANC-1 and AsPC-1 cells were transfected with short hairpin RNAs (shRNAs) specifically targeting ITGBL1 or the negative control (NC) for 48 h. For ITGBL1 overexpression, PANC-1 and AsPC-1 cells were transfected with ITGBL1 overexpression vector or empty vector for 48 h. For co-transfection, PANC-1 cells were co-transfected with ITGBL1 overexpression vector and JDP2 overexpression vector for 24 h. The transfections were mediated by Lipofectamine 3000 (Invitrogen, USA), according to the manufacturer's instruction.
Pancreatic Cancer Tissue and Cell Line Characterization
Aspc-1, Bxpc-3, Panc-1, and SW1990 cells were purchased from the American Type Culture Collection (Manassas, VA, USA), and the normal human pancreatic duct epithelial cells (hTERT-HPNE) were obtained from the Cell Bank Type Culture Collection of the Chinese Academy of Sciences (Shanghai, China). hTERT-HPNE, as well as Aspc-1, Bxpc-3 and SW1990 cells were grown in RPMI-1640 medium (Invitrogen, CA, USA) containing 10% fetal bovine serum (Gibco, Grand Island, NY, USA). Panc-1 cells were cultured in Dulbecco's modified Eagle's medium (Invitrogen, Grand Island, NY, USA) containing 10% FBS.

Modulating SNHG7 and miR-146b-5p in PC cells
Short hairpin RNA (shRNA) targeting SNHG7 (sh-SNHG7) and its negative control (sh-control), miR-146b-5p mimics (miR-146b-5p: 5'-UGAGAACUGAAUUCCAUAGGCU-3') and its control (miR-control: 5'-UUCUCCGAACGUGUCACGUTT-3'), miR-146b-5p inhibitor (5'-AGCCUAUGGAAUUCAGUUCUCA-3') and its control (inhibitor-control: 5'-CAGUACUUUUGUGUAGUACAA-3') were obtained from Shanghai GenePharma Co., Ltd. The sequences of SNHG7 (Accession: NR_024543.1) and Robo1 (Accession: GBYX01104758.1) were inserted into pcDNA vectors (Invitrogen; Thermo Fisher Scientific, Inc.) to construct overexpression plasmids, referred to as pcDNA-SNHG7 and Robo1, respectively. SW1990 and AsPC-1 cells were transfected with the constructed vectors or miRs (final concentration 50 µM) by using Lipofectamine® 2000 (Invitrogen; Thermo Fisher Scientific, Inc.) according to the manufacturer's instructions 48 h after transfection, the cells were used for further assays.

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.
