Figure Lengend Snippet: Figure 1 Elevated expression of erbB3 via stable transfection induces Akt activation and attenuates paclitaxel cyototoxicity in erbB2-overexpressing breast cancer cells. (a) MDA-MB-231 and SKBR3 cells were transfected with either pDsRed-Monimer-N1 or pDsRed-erbB3. After a 2-month selection with Geneticin, the stable clones of vector control (neo.1) or human erbB3 compli- mentary DNA (cDNA; B3.pool, B3.1, B3.2) were established, and the total cell lysates were subjected to western blot analyses with specific antibodies directed against erbB3, erbB2, epidermal growth factor receptor (EGFR), P-Akt, Akt, P- mitogen-activated protein kinase (P-MAPK), MAPK or b-actin. (b, c) The series of stable transfectants derived from MDA-MB-231 or SKBR3 cells were plated onto 96-well plates with complete culture medium (Dulbecco’s modified Eagle medium (DMEM)/F12, 10% fetal bovine serum (FBS)). After 24 h, the medium was replaced with control medium (fresh DMEM/F12, 0.5% FBS) or same medium containing indicated concentrations of paclitaxel for another 72-h incubation. The percentages of surviving cells from each cell line relative to controls, defined as 100% survival, were determined by reduction of MTS ((3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxy- methoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium,inner salt)). Data shows the representative of at least three independent experiments. Bars represent s.d. values.

doi: 10.1038/s41598-017-02029-z

Figure Lengend Snippet: NRG1 treatment increases ERBB4 activation in gastrocnemius muscle. C57BL/6JRJ (C57) control and db/db (Db) male mice were treated with vehicle (VHL; 0.9% NaCl solution; n = 8/each condition), or with NRG1 (50 μg . kg −1 ; n = 8/each condition), three days per week for eight weeks. Western blot analysis ( A ) cropped images) was used to quantify in gastrocnemius muscle samples the abundance of full length (115 kDa) ( B ) and cleaved (42 kDa) ( C ) NRG1 and the NRG1 cleavage index (the ratio between cleaved and full length NRG1) ( D ) as well as the abundance ( E ) and phosphorylation ratios ( F ) of ERBB2, ERBB3 and ERBB4. Results are the mean ± SEM (n = 8 per group) relative to the level in untreated healthy mice (C57-VHL, white bars). Diabetes (healthy vs db/db mice) and NRG1 (saline vs NRG1) effects were investigated with a 2 × 2 ANOVA. When a significant interaction was found, the Tuckey’s test was used for post-hoc multiple comparisons. *p < 0.05, **p < 0.01, ***p < 0.001, NS: not significant.

Article Title: Neuregulin 1 improves complex 2-mediated mitochondrial respiration in skeletal muscle of healthy and diabetic mice

doi: 10.1038/s41598-017-02029-z

Figure Lengend Snippet: Summary of the main effects of diabetes and NRG1 treatment in gastrocnemius muscle. The abundance of ERBB receptors is increased in diabetic db/db mice. This is associated with increased phosphorylation ratio of ERBB2 and decreased phosphorylation ratios of ERBB3 and ERBB4. Similarly, phosphorylation (activation) of the metabolic regulators AMPK, ACC and ACL is reduced in diabetic mice as well as Pparb and Tfam mRNA expression level. However, mitochondrial respiration in permeabilised fibres is similar in diabetic and control healthy mice. Chronic NRG1 treatment increases ERBB4 phosphorylation and tends to decrease ERBB3 phosphorylation. Among the regulators of the mitochondrial biogenesis pathway, only Pparb mRNA expression is slightly increased by NRG1. However, in NRG1-treated mice, complex 2-mediated mitochondrial respiration and complex 2 subunit abundance are increased. Effect of diabetes: red arrows. Effect of NRG1: green arrows.

Article Title: Function-blocking ERBB3 antibody inhibits the adaptive response to RAF inhibitor

doi: 10.1158/0008-5472.CAN-14-0464

Figure Lengend Snippet: Vemurafenib treatment relieves a negative feedback on ERBB3 transcription resulting in an increase of ERBB3 at the membrane. In the presence of its ligand, NRG1, ERBB3 heterodimerizes with ERBB2 to become active. Active ERBB3 recruits PI3K, which signals to the AKT pathway promoting survival of mutant BRAF melanoma cells treated with vemurafenib. Treatment with the anti-ERBB3 monoclonal antibody huHER3-8 outcompetes NRG1 and prevents the activation of ERBB3 and AKT signaling and enhances the efficacy of vemurafenib treatment.
