Cinnamaldehyde is an important compound of the cinnamon essential oil, and it is responsible for the most of the health benefits of cinnamon. Enriching foods such as milk with cinnamaldehyde can lead to greater utilization of cinnamaldehyde properties. In this study, we investigated the interaction of cinnamaldehyde with bovine alpha-lactalbumin. Analyzing the spectrum of alpha-lactalbumin in t...

Protein aggregation and precipitation is associated with many debilitating diseases including Alzheimer's, Parkinson's, and light-chain amyloidosis. β-Casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. Hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

The absorption of macromolecules was analysed by measuring serum concentrations of human alpha-lactalbumin after feeding human milk, using a competitive radioimmunoassay. The control group consisted of 78 children fed by cows' milk formula; concentrations of alpha-lactalbumin in their serum were low. The median concentrations in the different age groups varied between 7-13 micrograms alpha-lact...

The breast-specific antigen alpha-lactalbumin is expressed in >60% of breast cancer tissues. To evaluate the effect of gene therapy for breast cancer by controlling adenovirus replication with human alpha-lactalbumin promoter, we investigated the activity of a 762-bp human alpha-lactalbumin promoter. Alpha-lactalbumin promoter showed significantly higher activity in MDA-MB-435S and T47D breast ...

The breast-specific antigen A-lactalbumin is expressed in >60% of breast cancer tissues. To evaluate the effect of gene therapy for breast cancer by controlling adenovirus replication with human A-lactalbumin promoter, we investigated the activity of a 762-bp human A-lactalbumin promoter. A-Lactalbumin promoter showed significantly higher activity in MDA-MB-435S and T47D breast cancer cells tha...

To determine whether lactalbumin production by normal and neoplastic human mammary tissue is under the same control, the effect of prolactin treatment was studied in organ culture. Of 9 premenopausal normal breast samples, 6 produced lactalbumin in culture, and all 6 responded to prolactin treatment over 4 days. One biopsy of pregnant breast tested also responded to prolactin treatment, produci...

We describe the cloning of double-stranded cDNA synthesized from lactating human mammary gland total poly(A)-containing RNA, into the EcoRI site of the plasmid pAT153. Nine recombinants were shown to contain alpha-lactalbumin cDNA sequences as determined by positive hybridisation translation of complementary RNA. Restriction enzyme maps were determined for six of these. Alignment of the restric...

cDNA for rat alpha-lactalbumin has been cloned in bacterial plasmid, and its sequence has been analyzed. The DNA sequence analysis shows that rat alpha-lactalbumin has 17 extra residues beyond the COOH terminus of the alpha-lactalbumin isolated and sequenced to date from other species. The predicted COOH-terminal sequence is hydrophobic and proline rich and bears some resemblance to beta-casein...

Consumption of α-lactalbumin as dietary protein offers a beneficial effect on breast cancer development. Breast cancer was developed by gavage administration of single dose of dimethylbenz(a)anthracene (DMBA) in female rats, maintained on AIN-76A diet with either 20% casein or α-lactalbumin (a component of whey protein). All tumors were detected by palpation. After approximately 130 days of DMB...
