(A) Expression of TUB. Northern blot analysis of adult human tissues shows a ≈7–7.5-kb transcript with strong expression in heart, brain, testis, ovary, thyroid, and spinal cord after 48-hr exposure. TUB is also detected in skeletal muscle, prostate, small intestine, trachea, and adrenal gland. High expression of a 2.4-kb transcript is observed in liver and thyroid. (B) Expression of the TULP1 gene. No bands were observed on the same Northern blots when hybridized with a TULP1 probe after seven days of exposure. (C) Expression of the TULP2 gene. A ≈1.8-kb transcript is observed in testis. (D) Actin control.
