As shown in Figure 6, the mRNA levels of peripheral blood METTL3 and WTAP in SLE patients with alopecia was significantly decreased than that in SLE patients without alopecia (all P < 0.050); the mRNA level of peripheral blood ALKBH5 in SLE patients with rash and ulceration was significantly increased than that in SLE patients without rash and ulceration, respectively (all P < 0.050). Here, METTL3 is linked to alopecia.
