The aim of the present study was to evaluate the potential association between expression of β-catenin and gelsolin, and their influence on the migration ability of colon adenocarcinoma LS180 cells.
The most important markers for discriminating between the groups were CEA (classical carcinoid versus all others), KRas mutation (present in all mucinous cystadeno (carcino)mas), beta-catenin (goblet cell carcinoid versus left sided colonic adenocarcinoma) and chromogranin (goblet cell carcinoid versus right sided colonic adenocarcinoma).
We report on a case with constitutional mismatch repair deficiency caused by a novel MSH6 mutation leading to a T-cell lymphoma and colonic adenocarcinoma at six and 13 years of age, respectively.
The patient's adenocarcinoma of the colon and IPMN of the pancreas showed identical immunohistochemical staining profiles with loss of expression of MSH2 and MSH6 proteins and high levels of microsatellite instability.
Stable recombinant colonic adenocarcinoma cell (Caco-2) systems transfected with ABCB1 wild-type allele and variant alleles (1236 T, 2677T and 3435T) were constructed.
CT scan of abdomen/pelvis showed obstructive mass which was found to be colon adenocarcinoma which on further molecular analysis tested positive for KRAS, NRAS and BRAF mutations.
The study was performed on ovarian cancer cell line (OvBH-1), colon adenocarcinoma metastasis to ovary (SW626) and on cells isolated from ascitic fluids from patients with ovarian cancer: with (p53+) or without (p53-) p53 nuclear protein accumulation. p53 protein, Ser15, Ser20, Bax, Noxa and PgP protein expression was evaluated by means of immunocytochemical staining before and after chemotherapy.
Among the patients positive for TP53 mutations diagnosed with colon adenocarcinoma, 50% also showed at least one mutation in pathogenic genes of which 14% were BRAF, 33% were KRAS, and 3% were NRAS.
Curcumin induces apoptosis and cell cycle arrest via the activation of reactive oxygen species-independent mitochondrial apoptotic pathway in Smad4 and p53 mutated colon adenocarcinoma HT29 cells.
Patients ≥ 18 years old with histologically or cytologically confirmed adenocarcinoma of the colon or rectum and known KRAS status who were refractory or intolerant to two or more prior chemotherapy regimens were enrolled.
The anticancer activity and mechanism of action of SYNAP was studied in two- and three-dimensional models of human colon adenocarcinoma HCT116 cells with wild-type p53 and corresponding p53-null isogenic derivative cells, alone and in combination with known chemotherapeutic agents.
The authors report a case of a 73-year-old woman who had a right hemicolectomy for an ascending colon adenocarcinoma and showed a persistent elevation in the CEA marker during follow-up.
Words used in radiology reports, which have direct implications on disease course, tumor burden, and therapy, appear with differing frequency in patients with KRAS mutations versus wild-type colon adenocarcinoma.
We report a case of seminal vesicle metastasis from a primary ascending colon adenocarcinoma in a 49-year-old man, with elevating carcinoembryonic antigen as the only clinical sign.
An ¹⁸F-FDG PET/CT in an asymptomatic 74-year-old woman with a thyroid cytology suggestive of malignancy but uncertain about the origin of the tumor revealed an stage IV colon adenocarcinoma with KRAS mutation and multiple metastasis (thyroid, lung, and liver).
As a result, we found that the pretreatment of human colon adenocarcinoma (Caco-2) cells with 10-mM PTC significantly decreased the intracellular accumulation of P-gp substrate rhodamine 123 (Rho123) compared with the control after 90-min incubation.
Correlate the expression of CD44 and CD166 markers in metastatic colon adenocarcinoma and KRAS mutation status (wild-type/mutated) with clinical pathological features and patients' outcome.
High S100P expression was correlated with metastasis, as demonstrated by clinically relevant data, and predicted poor survival more effectively than preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels in colon adenocarcinoma.
We used the carcinoembryonic antigen promoter (CEA) to direct E gene expression (pCEA-E) towards colon cancer cells. pCEA-E induced a high cell growth inhibition of human HTC-116 colon adenocarcinoma and mouse MC-38 colon cancer cells in comparison to normal human CCD18co colon cells, which have practically undetectable levels of CEA.
Their tumour growth-inhibitory effects were assessed on human colon adenocarcinoma HCT116 cell lines with wild-type p53 and its p53-null derivative, followed by analysis of cell cycle and apoptosis.
