Figure 4. Effect of NBCe1 deletion on urinary ammonia and pH.
Top: effects on urine ammonia. Despite the metabolic acidosis associated with NBCe1 gene deletion, ammonia excretion decreased with heterozygous gene deletion and was suppressed significantly further with homozygous deletion. Bottom: effects on urine pH. Urine pH was significantly more acidic (lower) in mice with heterozygous NBCe1 deletion than in wild-type mice and was decreased significantly further by homozygous NBCe1 deletion.
