Figure Legend Snippet: PA provokes hypothalamic leptin resistance and ER stress. Notes: ( A ) mHypoE cells were treated with PA at indicated doses for 24 hours prior to leptin treatment. After 45 minutes, cells were prepared for Western blot analysis. Representative Western blots show levels of phospho-JAK2 (pJAK2), phospho-STAT3 (pSTAT3), total-STAT3, and β-Actin levels. ( B , C ) Quantification of pJAK2 and pSTAT3 normalized to β-Actin and total-STAT3, respectively. ( D ) mHypoE cells were treated with PA at indicated doses for 24 hours and subjected to Western blot analysis. The results show the levels of phosphor-PERK (pPERK), total PERK, CHOP, and β-Actin. ( E , F ) Quantification of pPERK and CHOP normalized to total-PERK and β-Actin, respectively. Results were expressed as mean ± SEM of three independent experiments at least. ** P <0.01, *** P <0.001 compared with control groups. Abbreviations: ER, endoplasmic reticulum; JAK2, Janus-activated kinase 2; STAT3, signal transducer and activator of transcription 3.
Techniques Used: Western Blot

Journal: BioMed Research International
doi: 10.1155/2019/3480569

Figure Legend Snippet: Expression of BiP, PERK, p-eIF2 α , ATF4, and IRE1 α after EGCG treatment. GAPDH was used as the loading control. The densitometry results are from three independent experiments and are expressed as mean ± SEM ( n =3) normalized to GAPDH, ∗ P < 0.05, ∗∗ P < 0.01, and ∗∗∗ P < 0.001, relative to their respective controls at each incubation time.
Techniques Used: Expressing, Incubation

Figure Legend Snippet: Mechanism of action of EGCG in colorectal cancer (CRC). ER stress is induced by EGCG and activates UPR proteins, PERK (with its downstream targets eIF2 α and ATF4), and IRE1 α . Caspase 3/7 activity is also enhanced, indicating apoptosis occurrence in the colorectal cancer cells.
Techniques Used: Activity Assay

doi: 10.1155/2021/5570796

Figure Legend Snippet: Curcumin treatment significantly inhibits the PERK-eIF2 α -ATF4-CHOP signaling pathway and the cleavage of caspase-12. After curcumin treatment (10 μ M) for 48 h, (a) the mRNA levels of GRP78 and CHOP were detected by qRT-PCR, and (b) Western blot was performed to determine the protein levels of GRP78, PERK, p-eIF2 α , eIF2 α , ATF4, CHOP, and cleaved caspase-12. (c) Protein bands of GRP78, PERK, ATF4, CHOP, and cleaved caspase-12 were quantified by densitometry, and relative protein levels were normalized to GAPDH. (d) Protein bands of p-eIF2 α were quantified by densitometry, and relative protein expression of p-eIF2 α was normalized to eIF2 α . Data are shown as the mean ± SD. ∗ P < 0.05, ∗∗ P < 0.01, and ∗∗∗ P < 0.001. GRP78: glucose-regulated protein 78; CHOP: C/EBP homologous protein; PERK: protein kinase-like endoplasmic reticulum kinase; eIF2 α : eukaryotic translation initiation factor 2 α ; ATF4: activating transcription factor 4; qRT-PCR: quantitative real-time polymerase chain reaction.
Techniques Used: Quantitative RT-PCR, Western Blot, Expressing, Real-time Polymerase Chain Reaction
