Title: Role of kallistatin in pediatric patients with pulmonary arterial hypertension.
Low expression of kallistatin was associated with unfavourable prognosis and platinum resistance in high-grade serous (HGSOC). Overexpression of kallistatin significantly inhibited proliferation and metastasis, and enhanced platinum sensitivity and apoptosis in ovarian cancer cells. These findings demonstrate that kallistatin serves as a prognostic predictor and provide a potential therapeutic target for HGSOC

patients with less severe excretory pancreatic insufficiency and lipid profile disorders had higher kallistatin level than the control group

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_001275962.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) has an alternate splice site in the 5' region, which results in translation initiation at a downstream AUG codon, compared to variant 1. The resulting isoform (2) has a shorter N-terminus, compared to isoform 1. Both variants 2 and 3 encode the same isoform 2.
