SLC3A2 and angioimmunoblastic T-cell lymphoma: IHC analysis of primary AITL samples from our center showed that SSRP1 protein levels were higher in AITL tissues than in normal tissues and were significantly correlated with SLC3A2 protein levels (p < 0.0001, R = 0.732) (Figure 6M and Figure S6O–Q, Supporting Information).
