Abstract
BACKGROUND: During the occurring and developing of tumor, tumor-educated platelets mRNA profiles were altered. Since platelets are anuclear, the level of mRNAs is probably post-transcriptional regulated by the splicing maturation of pre-mRNA and alternative splicing. Apoptotic chromatin condensation inducer 1 (ACIN1) has been shown to be a component of a splicing-dependent multiprotein exon junction complex (EJC) and was involved in mRNA metabolism associated with splicing. This study analyzed the expression of ACIN1 mRNA in platelets, and explored its potential as a biomarker of lung cancer.Entities:

1自然沉降时血浆高倍镜下(瑞氏染色,100×)观察到血小板和白细胞(左),低速离心时血浆高倍镜下(瑞氏染色,100×)观察到血小板富集而无白细胞(右)。
Platelets and leukocytes were observed in plasma which was obtained by natural sedimentation (left, Wright's stain, 100×); enriched-platelets without leukocytes were observed in plasma which was obtained by low-speed centrifugation (right, Wright's stain, 100×).
