In basal serum-containing growth medium, few cells developed neurites.

Furthermore, basal serum FT3, TSH and tumor volume in the patients with mutations were not significantly different from the group without mutations.

However, basal serum IgA levels are also elevated, suggesting that the pathology in these mice may be more complex than initially appreciated.

Only 21% of patients had basal serum cortisols collected at 8 a.m. Agreement between 8 a.m. baseline cortisol and LDCT was fair.
