[PMID: 36831488 PMCID: PMC9953800 DOI: 10.3390/cancers15041145] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 02/06/2023] [Accepted: 02/07/2023] [Indexed: 02/17/2023] Open
Abstract
This study is focused on the selective delivery and release of the plant-based anticancer compound eugenol (EUG) in colorectal cancer cells (CRC). EUG is an apoptotic and anti-growth compound in diverse malignant tumors, including CRC. However, EUG's rapid metabolization, excretion, and side effects on normal cells at higher dosages are major limitations of its therapeutic potential. To address this problem, we developed a "smart" enzyme-responsive nanoparticle (eNP) loaded with EUG that exposes tumors to a high level of the drug while keeping its concentration low among healthy cells. We demonstrated that EUG induces apoptosis in CRC cells irrespective of their grades in a dose- and time-dependent manner. EUG significantly decreases cancer cell migration, invasion, and the population of colon cancer stem cells, which are key players in tumor metastasis and drug resistance. The "smart" eNPs-EUG show a high affinity to cancer cells with rapid internalization with no affinity toward normal colon epithelial cells. NPs-EUG enhanced the therapeutic efficacy of EUG measured by a cell viability assay and showed no toxicity effect on normal cells. The development of eNPs-EUG is a promising strategy for innovative anti-metastatic therapeutics.

Abstract
Colorectal cancer (CRC) is one of the most widely diagnosed cancers worldwide. Despite notable improvements in therapeutic strategies available to CRC patients, late stages of CRC have a higher incidence rate of drug resistance, which is associated with a higher mortality rate. The development of therapeutic strategies that use nanoparticles as a drug delivery system has become one of the most promising potential approaches for cancer therapy. Previous studies have shown that a natural plant alkaloid, veratridine (VTD), suppresses colon cancer cell migration and invasion, two essential factors in tumor metastasis, through activation of the gene that encodes the tumor-suppressor protein UBXN2A. The goal of this study is to develop a nanoassembly to selectively deliver VTD to cancer cells and release it on demand while leaving normal cells intact. We packaged the targeted therapy anticancer molecule VTD inside mesoporous silica nanoparticles (MSNs) impermeable to the blood-brain barrier (BBB) and with selective affinity to CRC cells and sealed the VTD-loaded nanoparticles with an enzymatically cleavable protein. The particles will deliver and release VTD only at the targeted colorectal tumor sites. Since the enzyme MMP-7 protease is dominantly secreted by CRC cells, the release triggered by the enzymes will increase VTD concentration at tumor cells, enhancing the efficiency of the new therapy. We have proven the selective affinity of two types of VTD-carrying particles to CRC cells and enzyme- or acid-triggered VTD release. Negatively surface-charged MSNs showed significant affinity toward positively charged cancer cells but not negatively charged normal fibroblast colon cells, making VTD-MSNs a promising anticancer drug with minimal side effects.

Abstract
Besides cytotoxic DNA damage irradiation of tumor cells triggers multiple intra- and intercellular signaling processes, that are part of a multilayered, treatment-induced stress response at the unicellular and tumor pathophysiological level. These processes are intertwined with intrinsic and acquired resistance mechanisms to the toxic effects of ionizing radiation and thereby co-determine the tumor response to radiotherapy. Proteolysis of structural elements and bioactive signaling moieties represents a major class of posttranslational modifications regulating intra- and intercellular communication. Plasma membrane-located and secreted metalloproteinases comprise a family of metal-, usually zinc-, dependent endopeptidases and sheddases with a broad variety of substrates including components of the extracellular matrix, cyto- and chemokines, growth and pro-angiogenic factors. Thereby, metalloproteinases play an important role in matrix remodeling and auto- and paracrine intercellular communication regulating tumor growth, angiogenesis, immune cell infiltration, tumor cell dissemination, and subsequently the response to cancer treatment. While metalloproteinases have long been identified as promising target structures for anti-cancer agents, previous pharmaceutical approaches mostly failed due to unwanted side effects related to the structural similarities among the multiple family members. Nevertheless, targeting of metalloproteinases still represents an interesting rationale alone and in combination with other treatment modalities. Here, we will give an overview on the role of metalloproteinases in the irradiated tumor microenvironment and discuss the therapeutic potential of using more specific metalloproteinase inhibitors in combination with radiotherapy.

Abstract
BACKGROUND/AIM Matrix metalloproteinase 7 (MMP7) expression is highly associated with colorectal cancer and modulates tumour growth and invasion. Radiation injury induces inflammation with increases in MMP7 and in transforming growth factor beta (TGFβ). The aim of this study was to investigate the effect on MMP7 and TGFβ. expression in patients with rectal cancer undergoing different regimens of neoadjuvant radiotherapy (RT). PATIENTS AND METHODS We studied 53 patients in three RT treatment groups receiving RT of 25 Gy, long-term RT 50 Gy and controls receiving no RT. Three biopsies were obtained from each patient during the treatments: before RT, after RT and after surgery. Tissue samples were formalin fixed, paraffin embedded and tissue microarrays were constructed and stained for MMP7 and TGFβ. Mann-Whitney U-tests and Wilcoxon Z-tests were used to determine differences between patients before and after RT, and after surgery, as well as between the RT groups. RESULTS In all three patient groups, increases of MMP7 and TGFβ expression were observed after surgery. MMP7 expression was significantly increased in patients receiving short-term RT but TGFβ expression was not affected by RT. CONCLUSION 50 Gy Irradiation of rectal cancer gives less tumour activation of MMP7, whilst it is up-regulated by 25 Gy and surgery regardless of RT.

Abstract
Objective We sought to apply Shannon’s entropy to determine colorectal cancer genes in a microarray dataset.
Materials and Methods In the retrospective study, 36 samples were analysed, 18 colorectal carcinoma and 18 paired normal
tissue samples. After identification of the gene fold-changes, we used the entropy theory to identify an effective gene set.
These genes were subsequently categorised into homogenous clusters.
Results We assessed 36 tissue samples. The entropy theory was used to select a set of 29 genes from 3128 genes
that had fold-changes greater than one, which provided the most information on colorectal cancer. This study shows
that all genes fall into a cluster, except for the R08183 gene.
Conclusion This study has identified several genes associated with colon cancer using the entropy method, which
were not detected by custom methods. Therefore, we suggest that the entropy theory should be used to identify genes
associated with cancers in a microarray dataset.

Abstract
With the development of radiotherapeutic oncology, computer technology and medical imaging technology, radiation therapy has made great progress. Research on the impact and the specific mechanism of radiation on tumors has become a central topic in cancer therapy. According to the traditional view, radiation can directly affect the structure of the DNA double helix, which in turn activates DNA damage sensors to induce apoptosis, necrosis, and aging or affects normal mitosis events and ultimately rewires various biological characteristics of neoplasm cells. In addition, irradiation damages subcellular structures, such as the cytoplasmic membrane, endoplasmic reticulum, ribosome, mitochondria, and lysosome of cancer cells to regulate various biological activities of tumor cells. Recent studies have shown that radiation can also change the tumor cell phenotype, immunogenicity and microenvironment, thereby globally altering the biological behavior of cancer cells. In this review, we focus on the effects of therapeutic radiation on the biological features of tumor cells to provide a theoretical basis for combinational therapy and inaugurate a new era in oncology.

Abstract
Radiotherapy remains one of the corner stones in the treatment of various malignancies and often leads to an improvement in overall survival. Nonetheless, pre-clinical evidence indicates that radiation can entail pro-metastatic effects via multiple pathways. Via direct actions on cancer cells and indirect actions on the tumor microenvironment, radiation has the potential to enhance epithelial-to-mesenchymal transition, invasion, migration, angiogenesis and metastasis. However, the data remains ambiguous and clinical observations that unequivocally prove these findings are lacking. In this review we discuss the pre-clinical and clinical data on the local and systemic effect of irradiation on the metastatic process with an emphasis on the molecular pathways involved.

Abstract
BACKGROUND Matrix metalloproteases (MMPs) are key players in the progression and metastasis of cancer. MMPs cleave extracellular matrix components and in this way promote tumor growth, invasion and vascularization. MMPs also affect tumor progression by regulating availability and activity of growth factors, inflammatory cytokines and chemokines. Accordingly, several MMPs have been found to serve as prognostic indicators in solid tumors. Usually the increased levels of MMPs in patients' tumor tissue or serum/plasma are associated with poor outcome. Interestingly, recent results show that certain MMPs also serve as tumor suppressors. OBJECTIVE This review discusses the latest view on MMPs as diagnostic and prognostic indicators in cancer patients. METHODS Studies with clinical samples of 70 or more patients are included in particular. In addition, the possible roles of MMPs in future molecular diagnostics and in the evaluation of therapeutic responses are discussed. CONCLUSION MMP-9 in particular has shown prognostic value in various types of tumor, and its measurement in circulation, urine or tumor tissue might help in clinical surveillance of otherwise problematic patient cases. There is upcoming new knowledge on MMPs in therapy response evaluation, in which MMPs might be useful together with CT scans and other clinically more established prognostic factors. Certain MMPs have a dual role in terms of cancer-modulating properties and thus it is essential to evaluate their expression and function in tumor cells and host environment to select validated therapy targets but spare MMP antitargets.

Abstract
Background Medulloblastoma is a highly invasive cancer of central nervous system diagnosed mainly in children. Matrix metalloproteinase-9 (MMP-9) and urokinase plasminogen activator receptor (uPAR) are over expressed in several cancers and well established for their roles in tumor progression. The present study is aimed to determine the consequences of targeting these molecules on medulloblastoma progression. Methodology/Principal Findings Radiation is one of the foremost methods applied for treating cancer and considerable evidence showed that radiation elevated uPAR and MMP-9 expression in medulloblastoma cell. Therefore efforts are made to target these molecules in non-irradiated and irradiated medulloblastoma cells. Our results showed that siRNA-mediated knockdown of uPAR and MMP-9, either alone or in combination with radiation modulated a series of events leading to apoptosis. Down regulation of uPAR and MMP-9 inhibited the expression of anti-apoptotic molecules like Bcl-2, Bcl-xL, survivin, XIAP and cIAPI; activated BID cleavage, enhanced the expression of Bak and translocated cyctochrome C to cytosol. Capsase-3 and -9 activities were also increased in uPAR- and MMP-9-downregulated cells. The apoptosis induced by targeting MMP-9 and uPAR was initiated by inhibiting epidermal growth factor receptor (EGFR) mediated activation of STAT3 and NF-κB related signaling molecules. Silencing uPAR and MMP-9 inhibited DNA binding activity of STAT3 and also reduced the recruitment of STAT3 protein at the promoter region of Bcl-2 and survivin genes. Our results suggest that inhibiting uPAR and MMP-9 reduced the expression of anti-apoptotic molecules by inactivating the transcriptional activity of STAT3. In addition, treating pre-established medulloblastoma with siRNAs against uPAR and MMP-9 both alone or in combination with radiation suppressed uPAR, MMP-9, EGFR, STAT3 expression and induced Bak activation leading to apoptosis. Conclusion/Significance Taken together, our results illustrated that RNAi mediated targeting of uPAR and MMP-9 might have therapeutic potential against medulloblastoma.

Abstract
BACKGROUND Matrilysin (MMP-7) elevation after radiotherapy is shown in humans. Matrilysin regulates certain cytokines and the production of bactericidal proteins when the mucosa is exposed to bacterial antigens. We investigate the effect of irradiation on matrilysin and microflora in murine bowel, after modulation with antibiotics. METHODS Animals were divided into two different groups a radiation group (72 animals) and sham radiation group (36 animals). Animals were divided into smaller groups of six according to radiation dose (19 or 38 Gy or sham). Seven days before radiotherapy ampicillin 500 mg/kg/d was administered intramuscularly, in the antibiotic groups. An exteriorized segment of ileum was subjected to single high dose radiation (19 or 38 Gy). Samples were collected 2, 24, and 48 h and analyzed for microflora, MIP-2, TGF-β, and MMP-7. RESULTS The combination of antibiotics and irradiation leads to an early significant reduction of bacteria, down-regulates MIP-2, up-regulates TGF-β and elevation of MMP-7 to levels achieved by antibiotics or irradiation alone. Lactobacilli were reduced to non-existent levels after antibiotics. CONCLUSIONS Pretreatment with Ampicillin before irradiation and laparotomy in a murine model leads to Matrilysin over-expression as achieved by radiotherapy alone. Microfloral regulation does not affect MMP-7 stimulation after surgical or radiological trauma. Radiotherapy overrides the effect of antibiotics leading to an up-regulation of MMP-7, TGF-β and MIP-2 expression between 24 h and 48 h.

Abstract
Our previous work and that of other investigators strongly suggest a relationship between the upregulation of metalloproteinase-9 (MMP-9) and urokinase-type plasminogen activator receptor (uPAR) in tumor angiogenesis and metastasis. In this study, we evaluated the role of MMP-9 and uPAR in medulloblastoma cancer cell resistance to ionizing irradiation (IR) and tested the antitumor efficacy of siRNA (short interfering RNA) against MMP-9 [plasmid siRNA vector for MMP-9 (pM)] and uPAR [plasmid vector for uPAR (pU)] either alone or in combination [plasmid siRNA vector for both uPAR and MMP-9 (pUM)]. Cell proliferation (BrdU assay), apoptosis (in situ TUNEL for DNA fragmentation), and cell-cycle (FACS) analyses were carried out to determine the effect of siRNA either alone or in combination with IR on G2/M cell-cycle arrest in medulloblastoma cells. IR upregulated MMP-9 and uPAR expression in medulloblastoma cells; pM, pU, and pUM in combination with IR effectively reduced both MMP-9 and uPAR expression, thereby leading to increased radiosensitivity of medulloblastoma cells. siRNA treatments (pM, pU, and pUM) also promoted IR-induced apoptosis and enhanced IR-induced G2/M arrest during cell-cycle progression. While IR induces G2/M cell-cycle arrest through inhibition of the pCdc2- and cyclin B-regulated signaling pathways involving p53, p21/WAF1, and Chk2 gene expression, siRNA (pM, pU, and pUM) alone or in combination with IR induced G2/M arrest mediated through inhibition of the pCdc2- and cyclin B1-regulated signaling pathways involving Chk1 and Cdc25A gene expression. Taken together, our data suggest that downregulation of MMP-9 and uPAR induces Chk1-mediated G2/M cell-cycle arrest, whereas the disruption caused by IR alone is dependent on p53- and Chk2-mediated G2/M cell-cycle arrest.

Abstract
A metaloproteinase-1 (MMP-1) e a metaloproteinase-7 (MMP-7) são proteinases da matriz extracelular (MEC), zinco-dependentes, envolvidas no processo inicial da carcinogênese por permitirem a invasão tumoral na célula e promover o processo de metastatização. O polimorfismo dessas proteinases tem sido estudado recentemente com o objetivo de validar susa expressão e/ou atividade como marcador prognóstico. Evidências cumulativas revelam importante papel das MMP's 1 e 7 em diferentes fases da carcinogênese. A MMP-1 tem ação direta sobre a principal proteína da MEC, que é o colágeno do tecido intersticial conectivo. Sua expressão aumentada neste tecido pode indicar alto potencial de disseminação tumoral em diferentes tipos de câncer, incluindo o colorretal. A associação deste aumento da expressão também parece ser verdadeira para a MMP-7.

Abstract
PURPOSE Novel strategies are needed to prevent the high mortality rates of several types of cancer. These high rates stem from tumor resistance to radiation therapy, which is thought to result from the induction of matrix metalloproteinases (MMP) and plasminogen activators. In the present study, we show that the modulation of MMP-9 expression, using adenoviral-mediated transfer of the antisense MMP-9 gene (MMP-9 adenoviral construct, Ad-MMP-9), affects breast cancer sensitivity to radiation. EXPERIMENTAL DESIGN In the present study, we used antisense Ad-MMP-9 to down-regulate the expression of MMP-9 in MDA MB 231 breast cancer cell lines in vitro before irradiation and subsequently incubated cells in hypoxic condition. In vivo studies were done with orthotopic breast tumors, and radiosensitivity was evaluated both in vitro and in vivo. RESULTS Ad-MMP-9 infection resulted in down-regulation of radiation-induced levels of hypoxia-inducible factor 1 alpha and MMP-9 under hypoxic conditions in MDA MB 231 breast cancer cells. In addition, Ad-MMP-9, in combination with radiation, decreased levels of the transcription factors nuclear factor-kappaB and activator protein 1, both of which contribute to the radioresistance of breast tumors. Finally, the triggering of the Fas-Fas ligand apoptotic cascade, which resulted in the cleavage of PARP-1 and caspase-10, caspase-3, and caspase-7, signifies the efficiency of combined treatment of Ad-MMP-9 and radiation. Treatment with Ad-MMP-9 plus radiation completely regressed tumor growth in orthotopic breast cancer model. CONCLUSIONS In summary, integrating gene therapy (adenovirus-mediated inhibition of MMP-9) with radiotherapy could have a synergistic effect, thereby improving the survival of patients with breast cancer.

Abstract
OBJECTIVE The matrix-metalloproteinases (MMPs) are thought to be critically involved in tumor invasion and metastasis. This retrospective study was aimed both to examine the gelatinase expression status in patients with rectal cancer and to investigate their prognostic value on survival. METHODS Sixty patients who underwent postoperative adjuvant chemoradiotherapy for Stage II and III rectal carcinoma were included. Expressions of MMP-2, MMP-9, and tissue inhibitors of MMP (TIMP-1 and TIMP-2) were analyzed by immunohistochemistry in paraffin-embedded primary rectal cancers and graded for the intensity and the percentage of cells stained. The relation between the expression of the markers studied and clinicopathologic features were evaluated for the primary study endpoint. The data were also analyzed using a multivariate Cox proportional hazards model for prognosis as a secondary endpoint. RESULTS Positive MMP-9 expression was observed in 70% of the tumors. The ratio of tumors with positive MMP-9 expression was increased according to N stage (P = 0.005), AJCC stage (P = 0.005), and tumor differentiation (P = 0.017). Overall survival was reduced in poorly differentiated tumors and tumors with positive MMP-9 expression (P = 0.002). Disease-free survival was lower in patients with positive MMP-9 expression (P = 0.007). Multivariate analysis indicated that positive MMP-9 expression was an independent predictor of reduced overall survival (P = 0.0103) and reduced disease-free survival (P = 0.0360). The other markers studied were associated with neither any clinicopathologic feature nor any survival parameter. CONCLUSION MMP-9 expression was observed in the tumors of patients with Stage II and III rectal carcinoma in comparable values and was characterized by poor overall survival and disease-free survival.

Abstract
We intend to analyse retrospectively whether the time interval ("gap duration" = GD) between preoperative radiotherapy and surgery in locally advanced rectal cancer (LARC) has an impact on overall survival (OS), cancer specific survival (CSS), disease free survival (DFS) and local control (LC). Two hundred seventy nine patients with LARC were entered in Trial 93-01 (hyperfractionated accelerated radiotherapy 41.6 Gy/26 Fx BID) shortly followed by surgery. From these 250 patients are fully assessable. The median GD of 5 days was used as a discriminator. The median follow-up for all patients was 39 months. GD > 5 days was a significant discriminator for actuarial 5-years OS (69% vs 47%, p = 0.002), CSS (82% vs 57%, p = 0.0007), DFS (62% vs 41%, p = 0.0003) but not for LC (93% vs 90%, p = non-significant). In multivariate analysis, the following factors independently predict outcome; for OS: age, GD, circumferential margin (CM) and nodal stage (ypN); for CSS: GD, ypN and vascular invasion (VI); for DFS: CEA, distance to anal verge, GD, ypN and VI; for LC: CM only. Gap duration predicts survival outcome but not local control. The patients submitted to surgery after a median delay of more than 5 days had a significantly better outcome.

Matrix metalloproteinase-9 expression correlated with tumor response in patients with locally advanced rectal cancer undergoing preoperative chemoradiotherapy. Int J Radiat Oncol Biol Phys 2007; 67:196-203.

Abstract
PURPOSE To analyze whether the expression of matrix metalloproteinases (MMPs) and their tissue inhibitors are associated with tumor response to preoperative chemoradiotherapy in rectal cancer patients. METHODS AND MATERIALS Forty-four patients who had undergone preoperative chemoradiotherapy were evaluated retrospectively. Treatment consisted of pelvic radiotherapy and two cycles of 5-fluorouracil plus leucovorin. Surgery was performed 6-8 weeks later. MMP-2, MMP-9, and tissue inhibitors of metalloproteinase-1 and -2 expression was analyzed by immunohistochemistry of the preradiation biopsy and surgical specimens. The intensity and extent of staining were evaluated separately, and a final score was calculated by multiplying the two scores. The primary endpoint was the correlation of expression with tumor response, with the secondary endpoint the effect of chemoradiotherapy on the expression. RESULTS Preoperative treatment resulted in downstaging in 20 patients (45%) and no clinical response in 24 (55%). The pathologic tumor response was complete in 11 patients (25%), partial in 23 (52%), and none in 10 (23%). Positive MMP-9 staining was observed in 20 tumors (45%) and was associated with the clinical nodal stage (p = 0.035) and the pathologic and clinical response (p < 0.0001). The staining status of the other markers was associated with neither stage nor response. The overall pathologic response rate was 25% in MMP-9-positive patients vs. 52% in MMP-9-negative patients (p = 0.001). None of the 11 patients with pathologic complete remission was MMP-9 positive. CONCLUSIONS Matrix metalloproteinase-9 expression correlated with a poor tumor response to preoperative chemoradiotherapy in rectal carcinoma patients.

Abstract
OBJECTIVE There is increasing evidence to indicate that MMP-7 plays a more important role in tumor progression than other MMPs. The aim of this study was to detect MMP-7 expression in human rectal cancer and normal rectal tissue and to determine whether it is correlated with invasion and metastasis of human rectal cancer. METHODS Eighty-six paired samples of rectal cancer and distant normal rectal tissue obtained from 100 inpatients were allocated into two groups (cancer group and control group). MMP-7 mRNA was detected by relative quantitative real-time RT-PCR and MMP-7 protein was examined by immunohistochemical staining and computerized image analysis. RESULTS MMP-7 mRNA expression in cancer group was higher than that in control group (P = 0.006), the expression ratios of 31 samples (37.35%) were <1 and 52 (62.65%) were >1. The mRNA expression level was correlated with Dukes Staging, histological differentiation grade and CEA level. The MMP-7 protein expression was in accordance with mRNA expression level. The positive degree of immunohistochemical staining in cancer group (1.82 +/- 0.03) was different from that in control group (1.17 +/- 0.13, P = 0.002). Moreover, in cancer group the positive staining degree in high-level mRNA cancers (2.04 +/- 0.18, n = 52) was higher than that in low-level mRNA ones (1.58 +/- 0.23, n = 31, P = 0.008). CONCLUSIONS Our results suggest that MMP-7 plays an important role in the progression of human rectal cancer. MMP-7 may be selected as a clinical diagnosis and prognosis index in rectal cancer.

Abstract
AIMS Matrix metalloproteinase (MMP) activity is increased after radiation. The aims of this study were to assess the time course of this increase and its effects on malignant cell invasion. METHODS Colorectal cancer (HCT 116, LoVo, C 170 HM 2, CaCO-2), fibroblast (46-BR.IGI, CCD-18 Co) and fibrosarcoma (HT1080) cell lines were irradiated at 4 gray (4 Gy) and matrix metalloproteinase gene and protein expression examined over a 96 h period by real time polymerase chain reaction and gelatin zymography. Invasion was assessed on Matrigel. Human rectal tumour MMP expression was compared before and after long course radiotherapy. RESULTS Radiation increased MMP gene expression of tumour cell lines, and resulted in increased MMP protein activity in the HT1080 line. HT1080 and HCT 116 in monoculture and LoVo in co-culture were more invasive after radiation at 48 h in vitro, but long course radiotherapy did not result in a consistent increase in MMP expression from human rectal tumour biopsies. CONCLUSIONS Radiation results in increased MMP expression for a limited time period. This results in an early increase in cell line invasion. Further clinical research is required to clarify if MMP inhibition given perioperatively following radiotherapy decreases local recurrence rates.

Abstract
Since the inception of staging for colorectal cancer (CRC), anatomic extent of disease has provided a solid foundation for predicting prognosis and guiding treatment in patients with CRC. However, the rapid advances in biologic and genetic technology have provided many new possibilities for enhancing the predictive power of the staging system. In this article, we will briefly discuss the history of CRC staging, identify the current parameters for American Joint Committee on Cancer staging including recent changes, and offer guidelines for future staging modifications. Although anatomic parameters have served us well for many years, their continued use as sole contributors to CRC staging is questionable. Staging in the future is likely to be a complicated combination of anatomic and biologic markers used together in mathematic modeling to group patients into prognostic risk groups, which can be used to guide tailored therapy.

Abstract
PURPOSE Radiotherapy is a very effective adjuvant treatment for rectal cancer with little side effects. Its killing effect on tumor cells seems to be more profound than the effect on normal tissue. The molecular events caused by irradiation are mainly analyzed in in vitro and animal models; investigations on human material are rare. In the current study, we analyzed the effects of irradiation on gene expression in normal and tumor tissue of rectal cancer patients. METHODS AND MATERIALS Normal and carcinoma tissue of patients from a randomized clinical trial of the benefits of preoperative radiotherapy were analyzed using the Affymetrix Human Cancer Gene Chip. Preoperative radiotherapy was given within 5 days prior to surgery. Results for normal tissue and tumor were compared to investigate the radiation-related differences between normal and tumor cells. We clustered the differentially expressed genes based on their functional annotation. Results were compared with immunohistochemical and literature data. RESULTS The majority of the investigated cancer-related genes remained unchanged by irradiation (92% in tumor tissue and 93% in normal tissue). The differentially expressed genes varied between tumor and normal tissue except for maspin and IL-8. Both in tumor and normal tissue, differentially expressed genes were present related to cell signaling and cycle control, apoptosis and cell survival and tissue response and repair. However, the spectrum of affected genes was totally different. CONCLUSION Pre-existing differences in gene expression between normal tissue and tumor tissue might explain the differences in their responses to radiation. This change in response may explain the clinical beneficial effect of radiotherapy on tumor cells (low local recurrence rate) and the less severe effects on normal tissue (minor side effects).
