For this and the following figures, lines on the top of the bars represent 1 SE. Full-lenght blots are shown in Supplementary Fig.

No differences were observed for 30 and 70 weeks of age. Different letters on the top of the bars denote statistical differences between ages.

And HES1 did not correlate with any Notch isoform.


The equation of linear regression and coefficient of Pearson are shown in each graph. Full size image Discussion The four Notch receptor paralogues were identified in the mammary gland of developing dairy heifers and their histological and subcellular localization described.

A complete Notch signaling pathway was identified during pre and post-puberty in heifers, including receptors, ligands and target genes. It is believed that individual receptors NOTCH1—4 may play distinct roles in regulating mammary gland development by their cell-type specific distribution.

For example, in humans a transcriptome analysis of cellular populations of the normal mammary gland showed that NOTCH1 and 3 were expressed mostly in luminal epithelial cells and NOTCH4 in myoepithelial cells 33 , In bovines, a recent transcriptomic analysis performed in pre-weaning heifers was able to detect activation of NOTCH1 in the mammary parenchyma 7.

In the present results, using immunohistochemistry, we identified specific patterns of Notch cellular and subcellular localization for each paralogue. Specific labeling for the four receptor paralogues in parenchymal cells epithelial and myoepithelial and stromal cells was evidenced with different intensities.

In particular, stromal cells have been proposed to encompass mesenchymal stem cells, which will give rise to the lineages that form the stroma 10 , or already differentiated cells, such as endothelial cells or fibroblasts The NOTCH4 paralogue showed the highest label in myoepithelial cells, in accordance to the NOTCH4 restriction to the basal compartment described in human mammary cells 36 , and which has been related to mammary stem cell population All receptors were found predominantly at membrane and cytoplasmic levels, except NOTCH4, which was predominantly nuclear suggesting differential activation of this paralogue during mammary pubertal development.

This is in accordance to suggested predominant role of NOTCH4 signaling in normal mammary gland development, participating in cell-fate determination When developmental patterns of the four paralogues were analyzed by Western blot, we observed some differences in the higher weight KDa band, which corresponds to the membrane receptor MD 37 , and in the lower weight 80 or 72 KDa band, which corresponds to the active NICD clivated domain, for NOTCH1, 3 and 4.

At this time, around the onset of puberty, mammary gland parenchyma undergoes active growth in response to high estrogen concentration 3 , 40 , coinciding with increasing estradiol receptor alpha expression in the mammary gland 39 , 41 , and increasing circulating estradiol and IGF1 levels 42 , To this respect, Notch signaling pattern has been related to estradiol receptor regulation in breast cancer 44 , 45 and in developmental studies in mouse Particularly, it has been proposed to control the differentiation of adipocytes and the development and remodeling of the vascular system, two critical components involved in the regulation of the development of the mammary gland With respect to NOTCH4, the proportion of its active form followed an opposite pattern during development, being maximal at 20 weeks of age prepubertally , and then minimal, during puberty and postpuberty, suggesting an earlier activation of this paralogue.

This may be in accordance to the current knowledge that NOTCH4 has a predominant role in stem cell maintenance and cell fate determination 35 , indicating a different role of this paralogue in mammary gland development.

Overexpression of NOTCH inhibits cell differentiation during embryogenesis 25 , and therefore the decrease in NOTCH4 during development may indicate its role in allowing a correct cell differentiation in this tissue. Different Notch receptors have partially different expression patterns in most tissues and at different stages of development. Moreover, specificity of the system within each tissue is reinforced by the diversity in the downstream targets activated by the NICD within each tissue.

It is therefore paramount to study receptors, ligands and target genes In the present work, the expression of HEY1 and HEY2 increased in the mammary glands between 30 and 40 weeks of age, while no modification was observed for HES1, the other target gene studied. No studies have been conducted yet in the prepubertal gland. However, the fact that Notch components were affected by castration 34 , suggested that estrogen, which strongly increases just before puberty, may modulate the pathway.

This is also coincident with the developmental increase in the mRNA expression of Notch ligands observed here.

Cross-talk between NOTCH and estrogen receptors had also been reported in breast cancer studies 50 , suggesting further interaction in this tissue.

Although the activation of the target genes may be the result of the activation of all the different Notch paralogues, the one-to-one regression studies points to the receptors with greatest participation in the activation of each gene in this tissue.

The Notch system during pubertal development of the bovine mammary gland

These results provide new evidence about the involvement of the Notch system in development of the bovine mammary gland. Importantly, the Notch system defines the context in which other pathways function to control proliferation, differentiation and cell survival, all processes which are critical for normal development and function of the mammary gland.

Understanding the complete system, membrane receptors and ligands, as well as target genes, will bring light to the fine tuning of this orchestrated process. At birth, female Holstein calves were placed in individual mobile pens, directly on the pastures for the first 60 days of life.

The pens were moved when the floor became dirty or humid. Ten heifers were randomly chosen from the herd to obtain serial mammary biopsies at different ages. Each heifer was biopsied at each age. Udders were cleaned with soap and water, then rinsed and disinfected with iodinated solution.

Each biopsy at 20, 30, 40, and 70 wk was obtained in a different place avoiding previous cicatrix. Only the samples with histologically verified mammary gland structure were used, and when the samples were not large enough, the portion destined to western blot processes was privileged. Samples were rinsed abundantly with tap water and PBS pH 7. Louis, MO.

They were then deparaffinized, rehydrated and washed in PBS.


Antigen retrieval was performed with sodium citrate 10 mM in microwave. Subsequently, slides were immersed in a 0. After brown color developed, the reaction was stopped by immersion in water, and sections were counterstained with hematoxylin, dehydrated, and coverslipped with DPX Sigma-Aldrich Inc. The pellet was discarded and an aliquot of supernatant was taken to quantify proteins by the Bradford method Fifty micrograms of proteins were mixed with 5X loading buffer.

Louis, MO , as internal control. It really looks like part of the camera until you peer closely.

Note that the mount only adjusts horizontally through the orientation of the suction cup. It takes great video, but GPS info is handy to document your location both during an accident, and on trips. At least the option would be nice. For traveling or other documentary purposes, it would be nice to have a front-only 30 fps option. The manual was actually found at www. I did exactly that in the office to investigate the user interface without sitting in the car.

Note that any of the streaking you see below is my fault—I tend to grab the cameras at the lens and smudge it up without noticing. The early evening capture below is included to show a driver who thought it would be clever to drive the wrong way up the one-way street I was coming down.

IDG This late evening video is a shout-out to the driver who was about to ignore the one-way sign on the street I was descending. Though there are streetlights around, this is still a rather dark area.

The streaking is largely my fault.

Sorry, Akaso. IDG In low-light situations, the Trace 1 still reveals a good amount of detail.Longman Top Notch is a dynamic communicative course. After puberty, the mammary gland undergoes repeated cycles of development and involution coordinated with pregnancy and lactation cycles.

Notch pathway activity has been associated with stem cells in many tissues, and therefore it has been used to trace lineages in some tissues like the intestine and the mammary gland 9 , 28 , Tax Student Book.

When developmental patterns of the four paralogues were analyzed by Western blot, we observed some differences in the higher weight KDa band, which corresponds to the membrane receptor MD 37 , and in the lower weight 80 or 72 KDa band, which corresponds to the active NICD clivated domain, for NOTCH1, 3 and 4. At 70 weeks it remained higher than at 20 weeks, but was not different from 30 and 40 weeks.
