I'm willing to listen if you want to share your knowledge. I may not have anything to contribute. I understand that telomeres are one of the latest hot topics in health care. But don't know much more. |

Let's start with this cosmindustry piece, although a bit fluffy.
New research highlights importance of telomere activity in aging
A focus on telomere activity has been playing an increasingly important role in high-tech anti-aging skin care solutions, and new research may point to further developments for the application of this technology.
Researchers at the National Institutes of Health (NIH) say they have identified a new pathway that sets the clock for programmed aging in normal skin and body cells, in a study that was published the Journal of Clinical Investigation.
Previous scientific research has already documented how telomeres wear away during cell division, which leads to degradation and eventually the death of the cell. Ultimately this leads to age-related cell damage, which in the case of skin, manifests itself in fine lines and wrinkles. Specifically the study has focused on the interaction between a toxic protein called progerin and telomeres, identifying how this toxin caps the ends of the telomeres. Progerin acts as a toxin and shortens telomeres. Progerin is a mutated version of a normal cellular protein called lamin A, which is encoded by the normal LMNA gene, the researchers point out. Lamin A helps to maintain the normal structure of a cell's nucleus, the cellular repository of genetic information.
Scientific studies have previously documented that the shorter or damaged telomeres tend to stimulate or activate production of progerin, which is the trigger for the cell damage. The more the telomere shortens, the higher the rate of progerin production.‘Our sense from the start was that progeria had a lot to teach us about the normal aging process and clues about more general biochemical and molecular mechanisms," NIH Director Dr. Francis Collins, M.D., Ph.D., and a senior author of the current paper.
Another study shows that the mutation that causes progeria – a rare disease that leads to premature aging in children - strongly activates the splicing of lamin A to produce the toxic progerin protein, leading to all of the features of premature aging suffered by children with the disease.
Interestingly, the researchers also observed that modifications in the splicing of LMNA are at play in the presence of the normal gene, a process known as RNA, and one that alters how a normal cell processes genetic information when turning into a protein.
The researchers have documented that this alteration in RNA splicing affects the processing of the LMNA messenger RNA, leading to an accumulation of the toxic progerin protein, the shortening of the telomeres, and cell degradation.
Telomere shortening is key "Telomere shortening during cellular senescence plays a causative role in activating progerin production and leads to extensive change in alternative splicing in multiple other genes," said lead author Kan Cao, Ph.D., an assistant professor of cell biology and molecular genetics at the University of Maryland, College Park.
Telomere Biology has become a hot topic in anti-aging skin care research. In a study released on November 28th 2010, in the online journal Nature, a team of researchers at Harvard Medical School reported on the first reversal of the aging process in a mammal.
By reactivating telomerase, they rejuvenated worn out organs in mice that were the equivalent biological age to 80 year old humans.
Notice how the Nature study gets woven in. The study had nothing to do with skin, but the industry is into wild extrapolations.
So, reactions? |

Whenever I read on this topic, I can't get images of Aubrey de Gray out of my head...his TED speeches are entertaining...and well, his persona.

OK, now having tantalized, I am going to share what I consider to be a really good paper. The full text pdf is available, so we can read it together and get a little deeper into the topic. Bottom line is that I think there are some research pathways worth following.
Here is the full text link: http://onlinelibrary.wiley.com/doi/10.1111/j.1600-0625.2010.01242.x/pdf
Here is the abstract only:
Buckingham EM, & Klingelhutz AJ.The role of telomeres in the ageing of human skin.Exp Dermatol. 2011 Apr;20(4):297-302
Department of Microbiology, University of Iowa, Iowa City, IA 52242, USA.
Abstract
Skin is a self-renewing tissue that is required to go through extensive proliferation throughout the lifespan of an organism. Telomere shortening acts as a mitotic clock that prevents aberrant proliferation such as cancer. A consequence of this protection is cellular senescence and ageing. The telomerase enzyme complex maintains telomere length in germline cells and in cancer cells. Telomerase is also active in certain somatic cells such as those in the epidermis but is almost undetectable in the dermis. Increasing evidence indicates that telomerase plays a significant role in maintenance of skin function and proliferation. Mutations in telomerase component genes in the disease dyskeratosis congenita result in numerous epidermal abnormalities. Studies also indicate that telomerase activity in epidermal stem cells might have roles that go beyond telomere elongation. Telomeres in skin cells may be particularly susceptible to accelerated shortening because of both proliferation and DNA-damaging agents such as reactive oxygen species. Skin might present an accessible tissue for manipulation of telomerase activity and telomere length with the potential of ameliorating skin diseases associated with ageing. |

Good write up.

The apple stem cell malarkey shot the blog into the nether regions.
Personally, I would not want my work posted next to that, as it lends credence to the bunk. Unfortunately. |

You will be glad to know that Nikki was confronted and willingly capitulated on that topic. She didn't write that piece (it was a guest blog, by a non-scientist) but she also didn't independently verify the facts, she admits. Note that she didn't edit out the strongly refutational comments. No cover up here. Her willingness to allow debate, be challenged, and to expand her knowledge base rather than defend a shaky position convinced me that she is one of the good guys. Because our mission is to support these sorts of efforts, I have agreed to help out in my area of expertise. So let's give Nikki credit for how she handled that. Stark contrast with that other site we won't mention that would rather die on the junk science trash heap than admit they don't know something. |

What do we know about colostrum (bovine?) as an active skincare topical? (or oral?)
Thanks, BFG |

Abstract
Mammals supply their newborn before birth, at birth or shortly after birth with antibodies, immunocytes and humoral constituents. This "borrowed immunity" is a form of passive immunization to protect the newborn against environmental pathogens until it establishes its own pathogen recognition and disposal systems. In cows, goats, horses and some other animal species, most immunoglobulins are obtained from the colostrum, the first milk after birth, via the gut but in humans the majority of immunoglobulins, and those of the IgG-class in particular, are acquired from the mother by placental transport in the weeks prior to parturition. It has long been known that the consumption of bovine colostrum by humans has therapeutic effects e.g. in gastrointestinal infections, but only since the second half of the last century has it been possible to prepare stable, standardized preparations of colostrum. These biologics are administered to patients in combination with standard therapies as so-called balanced supportive diets. Investigations with standardized colostrum preparations in animal models of human disease and estimates of bovine IgG activity in the human GI-tract, described in this review, have provided preclinical data supporting the use of bovine colostrum in human diseases. On the other hand, the number of bovine colostrum products with a sufficiently large and reliable database is limited and the precise nature of the therapeutic targets is still being evaluated.

It really is not funny, I would pass on bovine (or any animals) colostrum!  |

Epicuren makes a nice colostrum serum. It's used by lots of the "Hollywood celebrities." |

There are several smaller brands of colostrum cream, but the big names don't seem too interested.
Easy to DIY too, though you can only do small amounts because it's perishable like any dairy product.
Considering the good stuff in colostrum it could very well be the ideal ingredient for ageing skin or skin with inflammatory problems like rosacea or eczema

Something like a 'poor man's cytokine and growth factor serum'? |
