OBJECTIVE Independent studies have previously demonstrated that both the HIPK2 and BRAF genes are amplified and rearranged, respectively, in pilocytic astrocytomas (PAs). The purpose of this study was to further investigate the frequency of BRAF and HIPK2 alterations in PAs, the concordance of these events, and their relationship to clinical phenotype. (More)
Although evidence has shown the regulating effect of n-3 poly-unsaturated fatty acid (n-3 PUFA) on cell signaling transduction, it remains unknown whether n-3 PUFA treatment modulates estrogen signaling. The current study showed that docosahexaenoic acid (DHA, C22:6), eicosapentaenoic acid (EPA, C20:5) shifted the pro-survival and proliferative effect of(More)
OBJECTIVES To investigate metastasis associated in colon cancer 1 (MACC1) and MET expression in colorectal adenoma, Tis, early-stage invasive (T1 and T2), and advanced adenocarcinoma with liver metastasis using immunohistochemistry. METHODS Ninety-three paraffin-embedded colorectal tumor specimens were immunohistochemically analyzed for MACC1 and MET(More)
Quantitative in vitro autoradiography was used to determine if regional sex differences in estrogen receptor (ER) content and/or estrogen responsiveness, as indicated by an increase in progestin receptor (PR), are present in the adult guinea pig brain. Adult male and female guinea pigs were gonadectomized 1 week before subcutaneous injection of 25(More)
Patients with mucinous colorectal cancer generally have worse prognoses than those with the nonmucinous variety. The reason for this disparity is unclear, but may result from a differential response to adjuvant chemotherapy. We examined known molecular markers for response to common chemotherapy in these two histological subtypes. In all, 21 patients with(More)
Pilocytic astrocytomas (PAs, WHO grade I) are the most common brain tumors in the pediatric and adolescent population, accounting for approximately one-fifth of central nervous system tumors. Because few consistent molecular alterations have been identified in PAs compared to higher grade gliomas, we performed array comparative genomic hybridization using(More)
Excision Repair Cross-Complementing Rodent Repair Group 2 (ERCC2) plays an important role in DNA repair by eliminating bulky DNA adducts produced by platinum agents during the nucleotide excision repair pathway. Several studies have associated polymorphisms in ERCC2 with response to platinum therapy, lung cancer risk, and DNA repair capacity. This study(More)
BACKGROUND Currently, there is a lack of ideal biomarkers for predicting nodal status in preoperative stage of oesophageal adenocarcinoma (EAC) to aid optimising therapeutic options. We studied the potential of applying subtype macrophages to predict lymph node metastasis and prognosis in EAC. MATERIAL AND METHODS Fifty-three EAC resection specimens were(More)
There is limited information about the clinical and biological significance of prostate specific G protein coupled receptor (PSGR) in prostate cancer (PCa) initiation and progression. Here, we evaluated the expression of PSGR protein, studied its diagnostic and prognostic value in PCa, and also explored its role in cancer cell growth and invasion. The(More)
Estrogen signaling, through estrogen receptor (ER)α, has been shown to cause hypertrophy in the prostate. Our recent report has shown that epithelial ERα knockout (KO) will not affect the normal prostate development or homeostasis. However, it remains unclear whether ERα in different types of stromal cells has distinct roles in prostate development. This(More)
