Breast cancer (BC) is the second most common cancer in women. In the North Eastern Region (NER) of India, BC is emerging as an important concern as evidenced by the data available from population and hospital-based cancer registries. Studies on genetic susceptibility to BC are important to
BACKGROUND
Disparities of biomarkers' expression in breast cancer across different races and ethnicities have been well documented. Proline, glutamic acid, and leucine-rich protein 1 (PELP1), a novel ER coregulator, has been considered as a promising biomarker of breast cancer prognosis; however,
Proline analogue of melphalan (Mel-pro) was synthesized as a prodrug susceptible to the action of ubiquitously distributed, cytosolic imidodipeptidase-prolidase [E.C.3.4.13.9]. Conjugation of melphalan (Mel) with proline (Pro) through imido-bond resulted in formation of a good substrate for
In situ estrogen synthesis is implicated in tumor cell proliferation through autocrine or paracrine mechanisms especially in postmenopausal women. Several recent studies demonstrated activity of aromatase, an enzyme that plays a critical role in estrogen synthesis in breast tumors. Proline-,
Although prolidase [E.C.3.4.13.9] is found in normal cells, substantially increased levels are found in some neoplastic tissues. Prolidase evokes the ability to hydrolyse the imido-bond of various low molecular weight compounds coupled to L-proline. The synthesis of three proline analogues of
A number of novel proline-linked nitrosoureas (1-4) were synthesized and examined for cytotoxicity and influence on DNA and collagen biosynthesis in MDA-MB-231 and MCF-7 human breast cancer cells. Evaluation of the cytotoxicity of these compounds employing a MTT assay and inhibition of
BACKGROUND
Triple-negative breast cancer (TNBC) is associated with an aggressive clinical course due to the lack of therapeutic targets. Therefore, identifying reliable prognostic biomarkers and novel therapeutic targets for patients with TNBC is required. Proline, glutamic acid, leucine rich
Early cancer cell migration and invasion of neighboring tissues are mediated by multiple events, including activation of focal adhesion signaling. Key regulators include the focal adhesion kinase (FAK) and FAK-related proline-rich tyrosine kinase 2 (Pyk2), whose distinct functions in cancer
Invasive potentials of carcinomas greatly contribute to their metastasis, which is a major threat in most cancers. We have recently shown that Arf6 plays a pivotal role in breast cancer invasive activities and identified AMAP1 as an effector of GTP-Arf6 in invasion. Expression of AMAP1 correlates
Prolidase [E.C.3.4.13.9] is ubiquitously distributed cytosolic egzopeptidase that is known to cleave imido-bond of some low molecular weight compounds coupled to L-proline. Previously we have found that conjugation of antineoplastic drug--melphalan (Mel) with proline (pro) through imido-bond
Although prolidase [EC 3.4.13.9] is found in normal cells, substantially increased levels are found in some neoplastic tissues. Because prolidase possesses the ability to hydrolyse imido bonds of various low molecular weight compounds coupled to L-proline, we hypothesized that coupling of L-proline
A series of proline analogues of anthraquinone-2-carboxylic acid (1-3) were synthesized and evaluated for cytotoxic activity in the cultured breast cancer MCF-7 cells. The concentrations of 1, 2 and 3 needed to inhibit [3H]thymidine incorporation into DNA by 50% (IC50) were found to be 107 +/- 6
Current treatments are generally ineffective once breast cancer has metastasized; median survival is reduced to 2-3 yr. Previous research studies demonstrating potent synergistic antitumor activity of lysine, proline, ascorbic acid, and epigallocatechin gallate prompted us to investigate the in vivo
OBJECTIVE
The arginine to proline substitution at codon 72 represents a common aminoacidic polymorphism of the p53 protein. Recent data suggest that p53 codon 72 may modulate the response to cancer therapy. The aim of this study was to test the hypothesis that the p53 codon 72 genotype, evaluated in
Breast cancer cell proliferation is promoted by a variety of mitogenic signals. Classically estrogen is considered as most predominant mitogenic signal in hormone-dependent breast cancer and progesterone is primarily considered to have protective effect. However, it is suggested that some
