Increased plasma proteasome chymotrypsin-like activity in patients with advanced solid tumors.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The chymotrypsin-like (ChT-L) activity is one of the key regulators of intracellular protein degradation. Elevated proteasome ChT-L activity has recently been reported in plasma of patients with leukemia and myelodysplastic syndrome and suggested to have a prognostic significance. The aim of the

Differential sensitivity of breast cancer and melanoma cells to proteasome inhibitor Velcade.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Velcade (also known as PS-341 or Bortezomib) is a highly selective and reversible inhibitor of the 26S proteasome and is approved for the treatment of patients with advanced multiple myeloma. Here we investigated the anti-proliferative effect of Velcade on 4T1 breast cancer and B16F10 melanoma cells

A novel serine phosphorylation site detected in the N-terminal domain of estrogen receptor isolated from human breast cancer cells.

Ingia / Ingia

Activated estrogen receptor (ERalpha) plays a critical role in breast cancer development and is a major target for drug treatment. Serine phosphorylation within the N-terminal domain (NTD) contributes to ERalpha activation and may also cause drug resistance. Previous biochemical identification of

Wedelolactone Acts as Proteasome Inhibitor in Breast Cancer Cells.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Wedelolactone is a multi-target natural plant coumestan exhibiting cytotoxicity towards cancer cells. Although several molecular targets of wedelolactone have been recognized, the molecular mechanism of its cytotoxicity has not yet been elucidated. In this study, we show that wedelolactone acts as

Estradiol increases the production of alpha 1-antichymotrypsin in MCF7 and T47D human breast cancer cell lines.

Ingia / Ingia

alpha 1-Antichymotrypsin (Achy) is an antiprotease of the acute inflammation phase, which is also released by MCF7 human breast cancer cells in culture. Using a fluorimetric assay with the synthetic substrate L-Seryl-L-Tyrosyl-2-N-naphthylamide, we have shown that a medium conditioned by MCF7 cells

Changes in the Activity of Proteasomes and Calpains in Metastases of Human Lung Cancer and Breast Cancer.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

In patients with breast cancer and lung cancer, chymotrypsin-like and caspase-like activities of proteasomes and total activity of calpains in the primary tumor nodes and lymphogenic metastasis are elevated in comparison with the corresponding normal tissues. The development of lymphogenic

Curcumin inhibits proteasome activity in triple-negative breast cancer cells through regulating p300/miR-142-3p/PSMB5 axis

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Background: Curcumin functions as a proteasome inhibitor. However, the molecular mechanisms behind this action need more detailed explanations. Purpose: This study aimed to

Granzyme h serum levels variations with both reproductive hormone receptors, and related hormone receptors in breast cancer patients.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

BACKGROUND Breast Cancer (BC) is the most common cancer in Iranian women, meanwhile the Iranian patients are relatively young. Granzyme H (GZMH) is a functional cytotoxic serine protease of NK cell granules, which expands the cell death-inducing repertoire of innate immune system. GZMH is

SerpinI2 (pancpin) is an inhibitory serpin targeting pancreatic elastase and chymotrypsin.

Ingia / Ingia

SerpinI2/Pancpin/MEPI is a 46kDa member of the serpin (serine protease inhibitor) superfamily. It is downregulated in pancreatic and breast cancer, and associated with acinar cell apoptosis and pancreatic insufficiency when absent in mice. However, the target protease and protein properties of

Regulation of antitrypsin and antichymotrypsin synthesis by MCF-7 breast cancer cell sublines.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We have examined the synthesis of the protease inhibitors alpha 1-antitrypsin (alpha 1-AT) and alpha 1-antichymotrypsin (alpha 1-ACHY) by variants of the MCF-7 human breast cancer cell line. Spent medium from MCF-7 203P cells, grown in the absence of serum, was found to contain immunoreactive alpha

Tissue-type plasminogen activator in breast cancer: relationship with estradiol and progesterone receptors.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Plasminogen activator (PA) is an estradiol-inducible enzyme and therefore a potential marker for a functional estradiol receptor (ER) in human breast carcinomas. In this investigation tissue-type PA (t-PA) correlated significantly with both ER and progesterone receptors (PR) in human breast

Alpha 1-antitrypsin blocks the release of transforming growth factor-alpha from MCF-7 human breast cancer cells.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Human breast cancer cells synthesize and release a variety of growth-modulating substances in response to estrogen stimulation, and it is generally accepted that the growth-promoting effects of estrogens are due at least in part to this autocrine/paracrine mechanism. Several of these

Prostate-specific antigen may serve as a pathological predictor in breast cancer.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

PSA (prostate-specific antigen), a serine protease with chymotrypsin-like activity is the most useful tumor marker for prostate cancer screening, diagnosis, prognosis and monitoring. The identification of PSA in normal and tumoral mammary gland was regarded as a curiosity, but the confirmation of

Proteasome inhibition represses ERalpha gene expression in ER+ cells: a new link between proteasome activity and estrogen signaling in breast cancer.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Estrogen receptor-alpha (ERalpha) is a major therapeutic target of hormonal therapies in breast cancer, and its expression in tumors is predictive of clinical response. Protein levels of ERalpha are tightly controlled by the 26S proteasome; yet, how the clinical proteasome inhibitor, bortezomib,

Trypsin-chymotrypsin inhibitors from Vigna mungo seeds.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Three trypsin-chymotrypsin inhibitors were isolated from seeds of the black gram (Vigna mungo) with a procedure that entailed cation exchange chromatography on SP-Sepharose, anion exchange chromatography on Q-Sepharose, ion exchange chromatography by fast protein liquid chromatography (FPLC) on Mono
