Amphiregulin
Amphiregulin
Amphiregulin is a member of the epidermal growth factor (EGF) family of proteins.
It is involved in cell proliferation, differentiation, and survival.
Amphiregulin binds to and activates the EGF receptor, triggering intracellular signaling cascades that regulate various cellular processes.
It plays a role in the development and homeostasis of multiple tissues, including the skin, intestine, and mammary gland.
Dysregulation of Amphiregulin has been implicated in the pathogenesis of certain cancers and inflammatory disorders.
Researchers studying Amphiregulin can optimize their work using PubCompare.ai, an AI-powered platform that enhances reproducibility and accuarcy by helping locate the best protocols from literature, preprints, and patents, and discover the most reliable methods and products to advance their Amphiregulin research with ease.

Plasmids encoding AP-tagged EGFR ligands were constructed by inserting partial cDNAs for human TGFα, amphiregulin, epiregulin, EGF, betacellulin, and HB-EGF into the 3′ end of human placental AP cDNA on a pRc/CMV-based expression vector pAlPh. pAlPh contains an NH2-terminally located HB-EGF signal sequence. In all cases, the junction between AP and the EGFR ligand was placed next to the membrane-proximal EGF repeat. Release of the AP module into the culture supernatant thus requires cleavage at the COOH-terminal cleavage site. It should be noted that the results obtained with AP-tagged EGFR ligands corroborate previous results that TGFα, HB-EGF, and amphiregulin are cleaved by ADAM17 (Peschon et al., 1998 (link); Merlos-Suarez et al., 2001 (link); Sunnarborg et al., 2002 (link); Jackson et al., 2003 (link)). This validates the use of AP tags to measure ectodomain shedding for these substrates. In addition, the use of an AP tag has been independently validated using the TNF family members TNFα and TRANCE/OPGL (Zheng et al., 2002 (link); Chesneau et al., 2003 (link)). This strongly suggests that an AP tag, which provides a sensitive and quantitative means of measuring ectodomain shedding, should not interfere with the shedding properties of the other EGFR ligands tested here.

CD271low/MUC1high primary luminal epithelial cells were seeded at 6000 cells/cm2 on confluent fibroblast feeders of CD105high/CD26low and CD105low/CD26high cells, respectively, in modified breastoid base medium without HEPES [9 (link)] (DMEM/F-12, 1:1), 1 μg/ml hydrocortisone (Sigma-Aldrich), 9 μg/ml insulin (Sigma-Aldrich), 5 μg/ml transferrin (Sigma-Aldrich), 5.2 ng/ml Na-Selenite (BD Industries), 100 μM ethanolamine (Sigma-Aldrich), 20 ng/ml basic fibroblast growth factor (PeproTech), 5 nM amphiregulin (R&D Systems), with the addition of 10 μM Y-27632 (Axon Medchem), 1.8 × 10−4 M adenine (Sigma Aldrich) and the serum replacement B27 (20 μl/ml, Life Technologies) [6 (link)]. hMSC feeders cultured under similar conditions were used for comparison.
To determine whether luminal progenitors and differentiated cells responded differently to co-culture, FACS-sorted CD166 (ALCAM)high/laminin receptor 67LRhigh (EpCAMhigh/CD166high/LNR67high) or CD166high (EpCAMhigh/CD90low/CD166high) differentiated luminal cells versus 67LRlow (EpCAMhigh/CD166low/LNR67low) or CD166low (EpCAMhigh/CD90low/CD166low) progenitors [6 (link)] were confronted with either CD105high/CD26low or CD105low/CD26high cells under similar conditions. Epithelial structure formation was observed for up to three weeks by phase contrast microscopy and photographed (Leica DM IL).

RNA from GCM was extracted using TRIzol (Invitrogen) and purified with PureLink RNA columns (Life Technologies). RNA samples were treated with DNase I, and reverse transcription was performed with High-Capacity cDNA Reverse Transcription Kit (Life Technologies). Real-time PCR was performed using the TaqMan Gene expression assay (Applied Biosystems) following the manufacturer’s instructions, on cDNA specimens in triplicate, using 1× Universal PCR Master Mix (Life Technologies) and 1× mix containing specific receptors probes (Life Technologies).

IL-9, EGFR, AREG, and HIF-1α levels were measured by commercial enzyme-linked immunosorbent assay (ELISA) kits purchased from R&D Systems (Minneapolis, MN, USA), including Human IL-9 DuoSet ELISA (Catalog Number: DY209-05), Human EGFR DuoSet ELISA (Catalog Number: DY231), Human Amphiregulin DuoSet ELISA (Catalog Number: DY262), and Human/Mouse Total HIF-1 alpha/HIF1A DuoSet IC ELISA (Catalog Number: DYC1935-2). Briefly, 100 µL of samples or standards were added to the wells of plates and incubated for 2 h at room temperature. The plates were washed five times. One hundred microliters of the detection antibodies were added to each well and incubated for 2 h at room temperature. The plates were washed five times. One hundred microliters of streptavidin-horseradish peroxidases were added to each well and incubated at room temperature for 20 min. The plates were washed five times. One hundred microliters of substrate solutions were added to each well and incubated at room temperature for 20 min. Fifty microliters of stop solutions were added to each well. The optical density of each well was determined using a microplate reader set to 450 nm.

Oocytes still enclosed in the cumulus cells (CEOs) were injected with 12.5 ng/μl Il7-RL, Thumpd1-RL, or Tpx2-RL and 12.5 ng/µl of polyadenylated FL using a FemtoJet Express programmable microinjector with an Automated Upright Microscope System (Leica, DM4000B). Injected CEOs were pre-incubated for 3 h in culture medium supplemented with 2 μM milrinone, and then cultured in milrinone-free medium supplemented with 100 nM amphiregulin. After 16 h, the CEOs were denuded, collected in lysis buffer and frozen. Luciferase activities in the oocyte extracts were measured using a dual-luciferase reporter assay kit (Promega), and luminescence was detected with a SpectraMax L luminometer (Molecular Devices). Data are reported as ratios of RL and FL.

After the treatment period, treated cells or rat lung tissues were subjected to RNA isolation using RNAiso plus as described earlier (Andugulapati et al. 2020 (link)). Briefly, RNA was isolated using the TRIzol–chloroform method and total RNA was quantified using nano-drop. Isolated RNA (1 μg) was subjected to cDNA synthesis using a prime script cDNA synthesis kit as per the manufacturer’s instructions. Specified primers [IL-6, IL-1β, TNF-α, IL-8, CCL2, CCL3, CCL7, CXCL1, alveolar pulmonary stretch (amphiregulin), CC16, vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule (ICAM-1), and reference markers (GAPDH, β2M, and β-actin)] were designed using Primer-3 software and the respective sequences are shown in Table S1. RT-qPCR was carried out using SYBR green mix and the differences in mRNA expression of the specified genes were calculated as the fold change using the formula 2-ΔΔct and data were expressed as mean ± SEM.
