Expression profile of mammary genes coding for secreted proteases expressed during the tammar lactation cycle. (A) Gene expression profiles of proteases were examined by microarray analysis of mammary gland tissue collected from different phases of the tammar wallaby lactation cycle. Examples of some proteases (CTSC, TPSB1, CFD) are differentially expressed in different phases of lactation. (B, D, F). In contrast, the level of expression of some genes (CTSK, PRCP, GZMB) remained unchanged during lactation (C,E,G).
