H-Ile-Lys-Val-Ala-Val-OH trifluoroacetate salt

H-Ile-Lys-Val-Ala-Val-OH is one of the most potent active sites of laminin-1. H-Ile-Lys-Val-Ala-Val-OH promotes cell adhesion, neurite outgrowth, and tumor growth. H-Ile-Lys-Val-Ala-Val-OH stimulates BMMSC population growth and proliferation by activating MAPK/ERK1/2 and PI3K/Akt signalling pathways[1][2].

H-Ile-Lys-Val-Ala-Val-OH (0-2.5 mM, 0-48 h) 诱导骨髓间充质干细胞(BMMSC)增殖和增殖细胞核抗原(PCNA)合成[2]。 H-Ile-Lys-Val-Ala-Val-OH (5 mM, 24 h) 诱导 BMMSC 细胞周期，使细胞从 G0/G1 进入 S 期并阻止它们进入 G2/M 期[2]。 H-Ile-Lys-Val-Ala-Val-OH (0-2.5 mM, 0-48 h) 通过增强 BMMSCs 中 ERK1/2 和 Akt 的磷酸化水平激活 MAPK/ERK 和 PI3K/Akt 信号通路[2]。 Cell Proliferation Assay[2] Cell Line: BMMSC Concentration: 0, 0.004, 0.02, 0.1, 0.5 and 2.5 mM Incubation Time: 0, 12, 24, 36, 48 h Result: Stimulated proliferating cell nuclear antigen (PCNA) synthesis and induced proliferation of bone marrow mesenchymal stem cell (BMMSC) in a dose- and time-dependent manner. Cell Cycle Analysis[2] Cell Line: BMMSC Concentration: 5 mM Incubation Time: 24 h Result: Induced the BMMSC cell cycle for cells to enter S phase from G0/G1 and arrested them from entering G2/M phase; the increased proportion of S phase in cell cycle was considered to be a sign of BMMSC proliferation. Western Blot Analysis[2] Cell Line: BMMSC Concentration: 0, 0.004, 0.02, 0.1, 0.5 and 2.5 mM Incubation Time: 0, 12, 24, 36, 48 h Result: Increased significantly the levels of p-ERK1/2 and p-Akt in a dose- and time-dependent manner.
