Objectives: This study aimed to investigate the potential function of miR-214 in the apoptosis induction by targeting p53 in human colorectal cancer cells (CRC) in combination with doxorubicin (DOX). Methods: miR-214 mimics were transfected to HT-29 CRC cells. Following that, the transfected cells were treated with DOX. Cell viability, apoptosis, and migration were evaluated by MTT, flow cytometry, and scratch-wound motility assays, respectively. Furthermore, the expression level of miR-214 and p53 was evaluated by qRT-PCR. Results: miR-214 transfection significantly inhibited the cell proliferation rate (P<0.05), induced apoptosis (P<0.05), and harnessed migration (P<0.05) in the HT-29 cells after 48 h. Furthermore, more effectiveness was observed in combination with DOX. Additionally, miR-214 transfection led to a reduction in p53 expression offering that it might be a potential target for miR-214. Conclusion: In conclusion, miR-214 sensitizes HT-29 cells to doxorubicin by targeting p53 indicating the significant role of this miRNA in colorectal cancer chemotherapy.

The transient receptor potential vanilloid member 4 (TRPV4) is a non-selective calcium (Ca2+)-permeable channel which is widely expressed in different types of tissues including the lungs, liver, kidneys and salivary gland. TRPV4 has been shown to serve as a cellular sensor where it is involved in processes such as osmoregulation, cell volume regulation and thermoregulation. Emerging evidence suggests that TRPV4 also plays important roles in several aspects of cancer progression. Despite the reported roles of TRPV4 in several forms of cancers, the role of TRPV4 in human colorectal cancer remains largely unexplored. In the present study, we sought to establish the potential role of TRPV4 in colorectal cancer by assessing TRPV4 expression levels and investigating whether TRPV4 pharmacological modulation may alter cell proliferation, cell cycle and cell death in colorectal cancer cells. Quantitative real-time PCR analysis revealed that TRPV4 mRNA levels were significantly lower in HT-29 cells than normal colon CCD-18Co cells. However, TRPV4 mRNA was absent in HCT-116 cells. Pharmacological activation of TRPV4 with GSK1016790A significantly enhanced the proliferation of HT-29 cells while TRPV4 inhibition using RN 1734 decreased their proliferation. Increased proliferation in GSK1016790A-treated HT-29 cells was attenuated by co-treatment with RN 1734. Pharmacological modulation of TRPV4 had no effect on the cell cycle progression but promoted cell death in HT-29 cells. Taken together, these findings suggest differential TRPV4 expression levels in human colorectal cancer cells and that pharmacological modulation of TRPV4 produces distinct effects on the proliferation and induces cell death in HT-29 cells.

Abstract Background: To better explore the underlying mechanism of liver metastatic formation by placenta-specific protein 1 (PLAC1) in human colorectal cancer, we investigated the proliferation, invasion and angiogenic capabilities of human colorectal cancer cell lines with different liver metastatic potentials as well as the mechanism of action of PLAC1 in the metastatic process. Methods: The expression of PLAC1 was detected by reverse transcriptase PCR, western blot and real-time PCR. The effect of PLAC1 on metastatic potential was determined by proliferation, invasion, and angiogenesis assays, including an in vitro coculture system consisting of cancer cells and vascular endothelial cells that were used to detect the relationship between cancer cells and angiogenesis. In addition, we also determined PLAC1 downstream targets that preferentially contribute to the metastatic process. Results: PLAC1 was expressed in HT-29, WiDr and CaCo-2 colorectal cancer cells but not in Colo320 colorectal cancer cells. PLAC1 could not only significantly enhance the proliferation of CoLo320 and human umbilical vein endothelial cells (HUVECs) but could also promote the invasion of CoLo320 cells. The angiogenesis of HUVECs was enhanced by PLAC1 in a dose-dependent manner. In cocultured systems, angiogenesis was significantly increased by coculture with HT-29 cells. In addition, PLAC1 could promote angiogenesis in coculture with HT-29 cells. Furthermore, PLAC1-enhanced metastatic potential of colorectal cancer cells was dependent on activation of the PI3K/Akt/NF-κB pathway. Conclusions: The activation of PI3K/Akt/NF-κB signaling by PLAC1 may be critical for the metastasis of colorectal cancer cells. According to our results, we suggest that modification of PLAC1 function might be a promising new therapeutic approach to inhibit the aggressive spread of colorectal cancer.

Colorectal cancer (CRC) is one of the most common malignancies and most frequent cause of cancer death worldwide. The activation of both NF-κB and STAT3 signaling and the crosstalk between them play an important role in colorectal tumor.Helicteres angustifoliaL. is a type of commonly used Chinese medicinal herb and possesses a wide variety of biological activities. In the present study, we investigate the effects of three triterpenes fromH. angustifolia(HT) such as helicteric acid (HA), oleanic acid (OA), and betulinic acid (BA), on inhibiting CRC progression. Our results showed that HT extracts could decrease proliferation and induce apoptosis in HT-29 colorectal cancer cells. Moreover, HT extracts could suppress LPS-triggered phosphorylation of IKK, IκB, and NF-κB, attenuate IL-6-induced phosphorylation of JAK2 and STAT3, and suppress the expression of c-Myc, cyclin-D1, and BCL-xL, the downstream gene targets of NF-κB and STAT3. Therefore, HT extracts showed potent therapeutic and antitumor effects on CRC via inhibiting NF-κB and STAT3 signaling.
