glutamic/breast neoplasms

BACKGROUND This study investigated the use of serum amino acids and organic acids profiles as the novel metabolites for screening breast cancer (BC) patients. METHODS A total of 116 subjects as training set were divided into the following three groups: BC patients (n= 34), benign (BE) patients (n=

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,

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-,

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

Cisplatin (cis-diaminodichloroplatinum, CDDP) loaded methoxy poly (ethylene glycol)-block-poly (glutamic acid-co-phenyl alanine) [mPEG-b-P (Glu10 -co-Phe10 ) (PGlu10 ) and mPEG-b-P (Glu20 -co-Phe10 ) (PGlu20 )] nanoparticles with two different formulations (CDDP/PGlu10 and CDDP/PGlu20 ) are

Vascular disrupting agents (VDAs) have great potential for cancer treatment. Poly(l-glutamic acid)-combretastatin A4 conjugate (PLG-CA4) is a novel class of VDAs. Though it has notable antitumor activity, it can induce host immune responses that promote tumor growth. Here, PLG-CA4 induces the

The advantage of polymeric drug carriers lies in the uptake of the polymer nanoparticles by cancer cells before they release the drug, thereby reducing its toxic effects on healthy cells. A poly(gamma-glutamic acid)-b-poly(epsilon-caprolactone)-b-poly(gamma-glutamic acid) block copolymer was

The new anticancer agent poly(L-glutamic acid)-paclitaxel (PG-TXL) is a conjugate of paclitaxel and the water-soluble polyglutamate carrier. The observation that PG-TXL appears to possess antitumor activity superior to free paclitaxel in preclinical studies suggests that PG-TXL might possess

The intrinsic characteristics of the tumor microenvironment (TME), including acidic pH and overexpression of hydrolytic enzymes, offer an exciting opportunity for the rational design of TME-drug delivery systems (DDS). We developed and characterized a pH-responsive biodegradable poly-L-glutamic acid

This paper reports on a sensitive and selective method for the detection of Michigan Cancer Foundation-7 (MCF-7) human breast cancer cells and MUC1 biomarker by using an aptamer-based sandwich assay. A biocompatible nanocomposite consisting of multiwall carbon nanotubes (MWCNT) and poly(glutamic

In recent years, researchers were attracted to nanomaterials components for their potential role in cancer treatment. This study aimed to develop a novel and biocompatible cobalt hydroxide (Co(OH)₂) nano-flakes that is functionalized by glutamic acid (Glu) and conjugated to

Increased glutamine metabolism is a hallmark of cancer. Mitochondrial glutamic pyruvate transaminase (GPT2) catalyzes the reversible transamination between alanine and α-ketoglutarate (α-KG), also known as 2-oxoglutarate, to generate pyruvate and glutamate during cellular glutamine catabolism.

Bone is the most common organ affected by metastatic breast cancer. Targeting delivery of drugs to bone may not only enhance the treatment efficacy, but also reduce the quantity of drug administered. In order to increase the distribution of paclitaxel (PTX) in bone, herein, a novel bone

An easily administered cis-dichlorodiammineplatinum (II) (CDDP) formulation with less toxicity and greater antitumor effect would be extremely valuable. We describe PGA-CDDP, a water-soluble CDDP derivative. The hydrolyzed gamma-PGA has a molecular weight between 45 and 60 kDa, and is a
