OBFC1, 0.25 mg. CST complex subunit STN1, also known as OBFC1, is a component of the CST complex, a complex that binds to single-stranded DNA and is required to protect telomeres from DNA degradation.
Our study revealed that depletion of ataxin‐3 increases the levels of ubiquitylated MDC1, while at the same time reducing its residence time at DNA breaks, consistent with the idea that ubiquitylation of MDC1 is the primary signal that regulates its release from chromatin. Additionally, our findings reveal that ubiquitylation of MDC1 is regulated by ataxin‐3 in a manner that requires its catalytic activity. Notably, whereas ataxin‐3 depletion had a strong effect on the MDC1 exchange at sites of DNA damage, the net effect on the steady‐state accumulation of MDC1 at DSBs was subtle, similar to what has been found for RNF4 depletion (Galanty et al, 2012). This suggests that the rapid dissociation of MDC1 in the absence of ataxin‐3 is likely to be compensated by the instant recruitment of new MDC1 molecules, resulting in a dynamic cycle in which the residence time of individual molecules is severely reduced and insufficient to properly activate the response to DSBs. Consistent with this ...
Sample is very successful tethering wise, lot of tethers, but most of them broke during the beginning of overstretching after a good FTC. Very very few tethers overstretched; 11 good tethers out of 75 attempts (15% efficiency). I selected some of the beast segments; force goes from 59 to 66pN at 1750nm LDNA at which the DNA starts overstretching but the data is good within the error range of stiffness. This data is analyzed under quick conversion, because we have not got the geometry going so the data might change. Some tethers overstretched multiple times, i noticed every time the same tethers is overstretched the overstretching force depletes, but that is not case. I looked many many multiple overstretches and they looked very alike. ...

Some of the first things you will notice after a yoga class is increased flexibility however this may be short lived. The next day practitioners often wake up stiff and sore dues to inflammation. This is due to tissue damage from overstretching. If you feel really sore for a day or two after class listen to your body and push less during your stretches.". ...

Calf strain or tear is caused by overstretching or tearing of either of the 2 calf muscles. It usually starts with sudden pain in the back of the leg.
To the best of our knowledge, the present study is the first to investigate the frequency and prognostic value of ALDH1 expression in IBTR tissues. The cut-off level for the classification of positive ALDH1 expression was set at ,1% in the current study, as there is no standardized cut-off level or method currently available. The ALDH1 positive cells were counted in hot spots, and positive ALDH1 expression was detected in 20% of the primary tumor samples and 23% of the IBTR tissue samples. The frequency of patients with ALDH1-expressing primary breast cancer (20%) in the current study was similar to that observed in previous studies (19, 17.5%) (10,11); however, the ALDH1 expression the in IBTR group (23%) was higher. It was hypothesized that this variation was due to the dissimilarities between the IBTR and primary tumors. IBTRs included new primary tumors and true recurrences following adjuvant therapy. Therefore, ALDH1-positive cancer stem cells within true recurrence were able to survive ...

The Stowers Institutes Baumann Lab has demonstrated how human cells protect chromosome ends from misguided repairs that can lead to cancer. The work, published in The EMBO Journal, a publication of the European Molecular Biology Organization, follows the teams 2007 in vitro demonstration of the role of the hRAP1 protein in preventing chromosome ends from being fused to new DNA breaks.. Chromosomes are linear. Their ends (called telomeres) should look like DNA breaks to the proteins that repair them. But somehow, cells are able to distinguish chromosome ends from DNA breaks. In this work, the team demonstrated that the human RAP1 protein plays a key role in preventing chromosome ends from being fused to new DNA breaks. Chromosome end fusions result in genomic instability, which can cause cancer. These findings suggest that RAP1 plays a critical role in cancer prevention in humans.. "Protecting naturally occurring chromosome ends from erosion and fusions may increase longevity and reduce cancer ...
