To gain insight into the role of the CCN genes in human breast carcinomas, we quantified
connective tissue growth factor
(
CTGF
), WISP-1, CYR61, and human NOV (NOVH) mRNA expression levels in samples from 44 primary breast tumors and seven normal breasts using quantitative real-time PCR assay. Overexpression of
CTGF
, WISP-1, CYR61, and NOVH was found in 55 (24 of 44), 46 (20 of 44), 39 (17 of 44), and 11% (5 of 44) primary breast tumors, respectively. Statistical univariate analysis was performed to explore the links between expression of the CCN genes and clinical and pathological parameters. Interestingly, significant associations were found between
CTGF
expression versus stage, tumor size, lymph node status, and age at diagnosis; WISP-1 mRNA levels versus stage, tumor size, lymph node, and
HER-2/neu
overexpression; and CYR61 expression with stage, tumor size, lymph node, age, and estrogen receptor expression. In contrast to
CTGF
, WISP-1, and CYR61, no significant correlation was found between NOVH expression and any of the clinical and pathological factors. Furthermore, multivariate classification tree model analysis showed that stage and lymph node involvement were important for predicting
CTGF
expression in breast cancers; the stage, age, and
HER-2/neu
status were key factors for WISP-1 expression; and the stage, age, and estrogen receptor were valuable predictors for CYR61 expression. In summary, these results suggest that
CTGF
, WISP-1, and CYR61 may play a role in the progression of breast cancer and might serve as a valuable tool for monitoring tumor status of breast cancer patients.

One of the defining features of pancreatic ductal adenocarcinoma (PDAC) is the presence of extensive desmoplasia. The desmoplastic stroma consists of proliferating fibroblasts and pancreatic stellate cells that produce and deposit fibronectin and collagens, inflammatory cells and macrophages that produce chemokines and cytokines, nerve fibers that release nerve growth factors, and marrow-derived stem cells. Stroma production is facilitated by the abundance of growth factors, including fibroblast growth factors (FGFs),
epidermal growth factor (EGF) receptor
ligands, transforming growth factor-beta (TGF-beta) isoforms, and
connective tissue growth factor
. Due to its location in the pancreas, stromal cells and pancreatic cancer cells are also exposed to high insulin levels. The stromal compartment stores and synthesizes multiple growth factors and the heparan sulfate proteoglycans glypican-1 and syndecan-1. This unique microenvironment harbors and nourishes the cancer cells, facilitating their invasive and metastatic potential. Targeting the stroma may thus provide novel therapeutic options in this deadly malignancy.

Connective tissue growth factor (CTGF/
CCN2
) is a cysteine-rich matricellular protein that belongs to the CCN (CYR61, CTGF, NOV) protein family. It is highly expressed by human rhabdomyosarcoma cells and sustains their survival. In this study we investigated
CCN2
expression in a mouse model of spontaneous rhabdomyosarcomagenesis that combines
HER-2/neu
oncogene activation and p53 oncosuppressor gene inactivation (BALB-p53neu mice). Murine rhabdomyosarcoma cells showed a 4-26 fold increase in
CCN2
mRNA expression regarding to normal thigh muscle. Moreover, they expressed
CCN2
protein at levels comparable to human rhabdomyosarcoma cells. Therefore BALBp53neu mice might be useful for the evaluation of the role played by
CCN2
in rhabdomyosarcoma in vivo.
