Apple Polyphenol Phloretin Inhibits Colorectal Cancer Cell Growth via Inhibition of the Type 2 Glucose Transporter and Activation of p53-Mediated Signaling
Glucose transporters
(GLUTs) are required for glucose uptake in
malignant cells, and they can be used as molecular targets for cancer
therapy. An RT-PCR analysis was performed to investigate the mRNA
levels of 14 subtypes of GLUTs in human colorectal cancer (COLO 205
and HT-29) and normal (FHC) cells. RT-PCR (<i>n</i> = 27)
was used to assess the differences in paired tissue samples (tumor
vs normal) isolated from colorectal cancer patients. GLUT2 was detected
in all tested cells. The average GLUT2 mRNA level in 12 of 27 (44.4%)
cases was 2.4-fold higher in tumor compared to normal tissues (*, <i>p</i> = 0.027). Higher GLUT2 mRNA expression was preferentially
detected in advanced-stage tumors (stage 0 vs 3 = 16.38-fold, 95%
CI = 9.22–26.54-fold; *, <i>p</i> = 0.029). The apple
polyphenol phloretin (Ph) and siRNA methods were used to inhibit GLUT2
protein expression. Ph (0–100 μM, for 24 h) induced COLO
205 cell growth cycle arrest in a p53-dependent manner, which was
confirmed by pretreatment of the cells with a p53-specific dominant
negative expression vector. Hepatocyte nuclear factor 6 (HNF6), which
was previously reported to be a transcription factor that activates
GLUT2 and p53, was also induced by Ph (0–100 μM, for
24 h). The antitumor effect of Ph (25 mg/kg or DMSO twice a week for
6 weeks) was demonstrated in vivo using BALB/c nude mice bearing COLO
205 tumor xenografts. In conclusion, targeting GLUT2 could potentially
suppress colorectal tumor cell invasiveness
Pu-erh Tea Extract Attenuates Nicotine-Induced Foam Cell Formation in Primary Cultured Monocytes: An in Vitro Mechanistic Study
In
this study, the mechanisms by which pu-erh tea extract (PETE)
attenuates nicotine-induced foam cell formation were investigated.
Monocytes were purified from healthy individuals using commercial
antibodies coated with magnetic beads. We found that the nicotine-induced
(1–10 μM) expression of oxidized low-density lipoprotein
receptors (ox-LDLRs) and α9-nAchRs in monocytes was significantly
attenuated by 24 h of PETE (10 μg/mL; ∗, <i>p</i> < 0.05) cotreatment. Nicotine (1 μM for 24 h) significantly
induced the expression of the surface adhesion molecule ICAM-1 and
the monocyte integrin adhesion molecule (CD11b) by human umbilical
vein endothelial cells (HUVECs) and triggered monocytes to differentiate
into macrophages via interactions with the endothelium. After treatment
with nicotine (0.1–10 μM for 24 h), the HUVECs released
chemotactic factors (IL-8) to attract monocytes into the tunica intima
of the artery, and the monocytes then transformed into foam cells.
We demonstrated that PETE treatment (>1 μg/mL for 24 h; ∗, <i>p</i> < 0.05) significantly attenuates nicotine-induced (1
μM) monocyte migration toward HUVECs and foam cell formation.
This study suggests that tea components effectively attenuate the
initial step (foam cell formation) of nicotine-induced atherosclerosis
in circulating monocytes
