actinomycin d/breast neoplasms

Between 1962 and 1973, regionally recurrent breast cancer was treated in 156 patients by irradiation alone or irradiation with concurrent actinomycin-D. Thirty-two patients were entered into a randomized trial, and 124 patients were retrospectively reviewed. Local control with irradiation alone was

One of the major hurdles in the treatment of breast cancers is the inability of anti-cancer drugs to eliminate the breast cancer stem cells (BCSCs) population, which leads to disease relapse. The dearth in anti-cancer drugs that target BCSCs can be attributed to the absence of in vitro screening

Increasing evidence indicates that the Golgi apparatus plays active roles in cancer, but a comprehensive understanding of its functions in the oncogenic transformation has not yet emerged. At the same time, the Golgi is becoming well recognized as a hub that integrates its functions of protein and

Actinomycin D is generally administered by serial low-dose injection over 5-10 days. Recent recognition of prolonged serum and tissue half-lives suggests that high-dose intermittent injecton should be equally effective and less toxic. An intermitten single dose schedule was selected for this phase

Metabolic changes following estrogen stimulation and the inhibition of these changes in the presence of actinomycin D and cycloheximide were monitored continuously in perfused human breast cancer T47D clone 11 cells with 31P and 13C NMR techniques. The experiments were performed by estrogen rescue

The tyrosine kinase inhibitor sunitinib was recently approved for use against gastrointestinal stromal tumors and advanced renal cell carcinoma. Yet, the protective effect of sunitinib against breast cancer has been poorly investigated. In this study, we investigated the antiproliferative and

The study aimed to evaluate immune-stimulating effects of a well-known Thai folkloric remedy when used for adjuvant therapy with conventional chemotherapeutics for treatment of breast cancer. Immunostimulating influence of the remedy (215 mg/kg body weight per day) on NK cell activity and TNF-α

Matrix Metalloproteinase-2 (MMP-2) is secreted as a zymogen, the activation of which has been associated with metastatic progression in human breast cancer (HBC). Concanavalin A (Con A) has been found to induce activation of MMP-2 in invasive HBC cell lines. Con A effects on the expression of mRNA

Fibulin-1 is an extracellular matrix protein overexpressed in epithelial ovarian and breast cancers. In estrogen receptor (ER)-positive ovarian and breast cancer cell lines, fibulin-1 mRNA levels are markedly increased by estrogens. Transfection experiments using fibulin-1 promoter constructs

BACKGROUND Between 10% and 35% of women with operable breast cancer will experience an isolated locoregional recurrence following their primary treatment. There is currently no good evidence that adjuvant systemic treatment is effective in this situation and there is no standard treatment for women

1alpha,25-Dihydroxyvitamin D3 [1,25(OH)2D3], the active metabolite of vitamin D, is a potent inhibitor of breast cancer cell growth. Because the estrogen receptor (ER) plays a key role in breast cancer progression, we have studied the effects of 1,25(OH)2D3 on the regulation of ER in the

Background: Breast cancer (BC) remains the most prevalent malignancy and the leading cause of cancer death. Circular RNAs (circRNAs) have been discovered to serve as crucial regulators in BC. In the current work, we aimed to study the

Antimitotic drugs are key components of combination chemotherapy protocols for hematological and solid tumors. The taxanes (e.g., paclitaxel) bind to the β subunit of the tubulin heterodimer and reduce microtubule dynamics, leading to cell cycle arrest in G2/M. The effectiveness of combination

Vascular endothelial growth factor (VEGF) is a major inducer of tumor angiogenesis and an important prognostic factor in breast cancer. Hypoxia is an important inducer of VEGF expression but less is known of the role of hormones in VEGF regulation. We have studied the regulation of VEGF, VEGF-B,

The prolactin receptor (PRLR) mediates the diverse effects of prolactin, which in the mammary gland include the development of lobuloalveolar structures and increased tumor cell proliferation. Treatment of mammary carcinoma cells with the differentiating agent sodium butyrate (NaB) is known to
