Figure Lengend Snippet: Figure 6. MEK2 overexpression causes autistic-like behaviors in mice, and its inhibition can rescue premature differentiation in ASD organoids. A) Schematic of AAV2/9 vectors for expressing MEK2-EGFP. B) Immunostaining images displaying GFP expressed in the hippocampus, including the dentate gyrus (DG) and CA, colabeled with the DG granule cell marker Prox1. Scale bar: 200 μm (left), 50 μm (right). C) Schematic of the open field test (Left) and histograms (Right) presenting the center zoneduration time (AAV-NC: n = 14 mice, AAV-MEK2: n = 15 mice, ns p = 0.86) and center zone entries (AAV-NC: n = 14 mice, AAV-MEK2: n = 15 mice, ns p = 0.31) of the mice in the AAV-NC and AAV-MEK2 groups. D) Schematic of the 3-chambered

Article Title: MAP kinase pathway gene copy alterations in NRAS/BRAF wild-type advanced melanoma.

doi: 10.1002/ijc.29970

Figure Lengend Snippet: Figure 1. NRAS/BRAF/cKIT wild-type melanoma metastases can show activation of the MAP kinase (MAPK) signaling pathway. (a) BRAFV600E, MEK1/2, MEK2, phosphorylated MEK (p-MEK), ERK1/2, ERK2 and phosphorylated ERK (p-ERK) expression levels in a representative NRASwild-type/ BRAFwild-type/cKitwild-type metastatic melanoma specimen. 1003 and 4003 magnifications are shown for each of the immunohistochemical (IHC) stainings. (b) IHC analyses of members of the MAPK signaling pathway in NRAS mutant (NRAS), BRAFV600E mutant (BRAF) and NRASwild-type/ BRAFwild-type/cKitwild-type (WT) melanoma subgroups. Y-axis shows the overall IHC score (0–12) calculated based on the quantity and intensity of the staining. Asterisks show p-values <0.05.

Article Snippet: 4 mm sections of formalin-fixed paraffin-embedded melanoma metastases were stained with antibodies against BRAFV600E (Spring Bioscience, Cat. No. E19290), total MEK (MEK1/2, Cell Signaling, Cat. No. 4694), MEK2 (Abcamab32517), phosphorylated MEK (Phospho-MEK1/2 [Ser221], Cell Signaling, Cat. No. 2338), total ERK (p44/42 MAPK [Erk1/2], Cell Signaling, Cat. No. 4695), ERK2 (Abcamab32081) and phosphorylated ERK (Phospho-p44/42 MAPK [Erk1/2][Thr202/Tyr204], Cell Signaling, Cat. No. 4376) using standard protocols.
