Association of serum annexin A1 with treatment response and prognosis in patients with esophageal squamous cell carcinoma.

Objective: Annexin A1 (ANXA1), a calcium-dependent phospholipid binding protein, is known to be regulated by microRNA-196a (miR-196a) in esophageal adenocarcinoma, and its high expression in tumor tissue is correlated with the poor prognosis of esophageal squamous cell carcinoma (ESCC). However, the role of ANXA1 in the serum of patients with ESCC remains unclear.

Materials And Methods: In this study, we used enzyme-linked immunosorbent assay to evaluate the levels of ANXA1 and real-time polymerase chain reaction to detect the expression of miR-196a in the serum of ESCC patients (healthy donors as controls) and evaluated the relationship between ANXA1 and clinical outcomes.

Expression of PPARγ and PTEN in human colorectal cancer: An immunohistochemical study using tissue microarray methodology.

Although aberrations of peroxisome proliferator-activated receptor γ (PPARγ) and phosphatase and tensin homolog (PTEN) expression have been identified in several other cancer types, certain previous studies have revealed that PPARγ is abundant in normal and malignant tissue in the colon. The question of whether aberrant PTEN is involved in the initial stage or is a later event during colorectal carcinogenesis remains controversial. Relatively few studies have focused on the correlation of expression of PPARγ and PTEN in various tissues.
