Penn Researchers Throw Light on the Structure Of Smallpox Virus Protein

...ds that normally occurs during DNA replication and transcription of the viral genes. Upon initial infection, the poxviruses come already equipped with some proteins, including topoisomerases, to kick-start replication. The structure was determined in a collaborative effort between the Bushman lab and the lab of...

Research Identifies Osteoporosis Controlling Protein

...nown as WWP1; together, the pair degrades Runx2, a transcription factor that is the master regulator of osteoblast differentiation, which activates key bone formation genes. By removing Shn3 or WWP1, Runx2 doesnt degrade, which leads to increased bone mass. The authors believe that targeting Shn3 and WWP1 for dr...

Importance of Gene in Eye Development

... a member of class of master genes that encode for transcription factors. Transcription factors are proteins that bind to DNA and regulate the expression of other genes. The investigators discovered that, in mice, disruption of the SOX2 gene in neural retinal stem cells leads to a kind of abnormal development of t...

Researchers Purify Protein That Could Regulate Male Hormones

...hing is that H3K9 demethylation has been linked to transcription silencing, turning genes off. So that led us to pay attention to this protein's role in reversing whatever function K9 methylation might have," Zhang said. In their experiments, the researchers learned that consistent with reversing a marker of gen...

Novel method conceived, to achieve genome-wide gene silencing.

... SUMO holds on to the histones and acts to repress transcription of genes, and it does so at many different sites across the genome. While several other histone-related mechanisms have been identified for activating genes in yeast, this is the first one recognized as repressing gene transcription. The finding a...

Mystery behind the Formation of Vertebral Precursors Unraveled

Snail belongs to the extensively studied family of transcription factors. The Snail factors are known to control the transition of the epithelium to a mesenchyme state in cancer. //They are thought to play a role in controlling tumor invasion. Jacqueline Kim Dale, Ph.D., formerly a Senior Research Associate at t...

Non-Coding RNA Vital For Gene Activation And Protein Expression

...he function of cells can be modified by transgenic transcription of non-coding TRE RNA. Non-coding RNAs have been regarded to be inert, having a limited role in inducing expression or activation of genes followed by protein expression. The present research has highlighted that non-coding RNAs can have a wide ran...

Hepatitis C Occurs Even After Liver Transplantation

...ter the transplant operation utilizing the reverse transcription polymerase chain reaction assay, and linear regression was used to analyze the results. It was seen that the HCV RNA levels fell in the case of most patients during the course of the transplantation operation, which rose subsequently afterwards, u...

Scientists breaking theory of cortex formation

...erebral Cortex," Sur and Rubenstein point out that transcription factors are key. A transcription factor is a protein that binds DNA at a specific site where it regulates transcription, or the proce...

Biopsies Of Human Skin And Bone Marrow Support T Cell Development

...ve selection. Skin cell cultures expressed three transcription factors and a panel of autoantigens. The authors conclude that skin and bone marrow biopsies can thus be used to generate de novo functional and diverse T cell populations for potential therapeutic use in immunosuppressed patients. ...

Forensic Phonetics – Scientific Solution for Legal Problem

...identification, language or accent identification, transcription and authentication services are some of the broad avenues where the modality can be of help. Phonetic analysis is however very time consuming, requires the painstaking preparation of speech samples and close observation of their acoustic and other ch...

Role Of Estrogen In Breast-Cancer

Molecule responsible for muscle repair identified

...resulted in increase in proteins like the myogenic transcription factor MyoD that had led to faster muscle regeneration and repair after injury. Muscle regeneration after injury is important and when this does not happen due to disease or age, it may lead to muscles not being able to recover from damage due to e...

The researchers had collected saliva and blood from 32 patients suffering from oral squamous cell carcinoma and 40 patients with breast cancer. The mRNA from the samples was matched with those of healthy subject...
