However, only limited information is available in UIP regarding the expression of other molecules involved in cell migration, such as LAM5γ2, fascin, and heat-shock protein-27 (HSP27), a multifunctional stress-inducible molecule involved in the modulation of actin microfilament dynamics and cell migration [23-25]. Here, FSCN1 is linked to idiopathic pulmonary fibrosis.
