SCARA5 and lung carcinoma: Although all five SCARA family members were significantly downregulated in lung cancer tissues compared to those in normal lung tissues, only SCARA3 expression level in lung cancer tissues showed statistically significant relation with patient survival (SCARA1, p = 0.4195; SCARA2, p = 0.9921; SCARA3, p < 0.02224; SCARA4, p = 0.8694; SCARA5, p < 0.6959) (Supplementary Fig. S1).
