Other chromosomes furiously exchange genetic information with each other. (bioedonline.org)
However, an important challenge still facing breeders now is the ability to routinely perform DNA-introgression, a process by which distantly related chromosomes exchange genetic information that is passed onto progeny. (nature.com)

Mosaicism for a cell line with the der(8) and a normal cell line was also detected in a maternal half-cousin. (elsevierpure.com)
The der(8) was inherited from the maternal grandmother who had four abnormal cell lines containing the der(8), in addition to a normal cell line. (elsevierpure.com)

In the recent analysis, Tyler-Smith and his colleagues in Britain and China examined the Y chromosome of about 1,000 men in eastern Asia. (bioedonline.org)

Firstly, the overexpression of miRNA‑375 significantly suppressed cell proliferation, increased lactate dehydrogenase activity and induced apoptosis in HPV‑18(+) cervical cancer cells. (spandidos-publications.com)
However, the regulatory mechanisms of HPV infection and consequent immune escape reaction, persistent infection and cell proliferation and the regulatory mechanisms of vascular proliferation are poorly understood and require additional investigation ( 4 ). (spandidos-publications.com)
It affects cell proliferation, differentiation and inhibits apoptosis, and its role in tumor development has received attention ( 9 ). (spandidos-publications.com)
Overexpression of IGF-1 in serum and tissue alters the growth of normal cells and causes uncontrolled proliferation, inhibits differentiation and reduces apoptosis, resulting in the incidence and development of malignant tumors ( 10 ). (spandidos-publications.com)

segments of these chromosomes have translocated so that part of chromosome 2 is attached to 3, and 3 to 2. (lu.se)

it contains instructions for making all the protein molecules for all the different kinds of cells of the human body - neurons in the brain, red blood cells, bone tissue, liver cells, etc. (sciencedaily.com)
The overexpression of miRNA‑375 significantly increased caspase‑3 and caspase‑9 activities, induced B‑cell lymphoma 2 (Bcl‑2)/Bcl‑2‑associated X protein, tumor protein 53 and cyclin‑dependent kinase inhibitor 1 protein expression and suppressed cyclin D1 and survivin protein expression in HPV‑18(+) cervical cancer cells. (spandidos-publications.com)
The overexpression of miRNA‑375 significantly suppressed the levels of protein expression of ubiquitin‑protein ligase E3A (UBE3A) and Insulin‑like growth factor‑1 receptor (IGF‑1R) in HPV‑18(+) cervical cancer cells. (spandidos-publications.com)
UBE3A is associated with cervical cancer and may combine with the E6 proto-oncogene encoded by HPV16 within cervical cancer cells to form the E6/E6-AP protein complex through the ubiquitin proteasome pathway ( 4 ). (spandidos-publications.com)
[ 6 ] Cells deficient in the HPS5 protein maintain early-stage melanosome formation and Pmel-17 trafficking. (medscape.com)

By the 8-cell stage, remethylation becomes more pronounced than demethylation, resulting in an increase in global DNA methylation. (nature.com)
We therefore decided to investigate comprehensively the global and high-resolution DNA methylation dynamics during early development of a non-human primate (rhesus monkey, Macaca mulatta ). (nature.com)

Usually, this will make the cell initiate apoptosis leading to its own death, but sometimes mutations in the cell hamper this process and thus cause progression of cancer . (wikipedia.org)
To conclude, it was identified that the probable anti‑CA mechanism of miRNA‑375 modulates HPV through the UBE3A and IGF‑1R pathway in cervical cancer cells. (spandidos-publications.com)
Previous studies have identified that UBE3A exhibits abnormal expression in numerous tumor cells, including prostate, cervical and breast cancer ( 6 , 7 ). (spandidos-publications.com)
The term "oncotarget" encompasses all molecules, pathways, cellular functions, cell types, and even tissues that can be viewed as targets relevant to cancer as well as other diseases. (oncotarget.com)
Because tumor-derived, cell-free DNA (cfDNA) is often released from cancer cells and circulates in the bloodstream, we hypothesized that breast cancer development is associated with changes in the amount of telomeric cfDNA that can be detected in the plasma. (oncotarget.com)
The image shows chromosomes from a cancer patient. (lu.se)
He has spent over 30 years studying various aspects of the changes to chromosomes that lead a cell to change and develop into a cancer cell, with a particular focus on leukaemia. (lu.se)
almost all tumours have chromosome changes and some are typical of different types of cancer. (lu.se)

Wilhelm Roux suggested that each chromosome carries a different genetic configuration , and Boveri was able to test and confirm this hypothesis. (wikipedia.org)
