GLI1 and Lassa fever: It has been well demonstrated that the Hedgehog pathway modulates several important aspects of cell function, including cell proliferation, activation, and differentiation, and Hedgehog pathway targeting is a promising direction for fibrosis treatment.21 To further confirm the effect of Hedgehog-Gli1 signaling activation on LF cell viability, we analyzed the effect of Gli1 expression on the proliferation and apoptosis of LF cells.
