Original Source: Repeated freeze-thaw cycles reduce the survival rate of osteocytes in bone-tendon constructs without affecting the mechanical properties of tendons.

Frozen bone-patellar tendon bone allografts are useful in anterior cruciate ligament reconstruction as the freezing procedure kills tissue cells, thereby reducing immunogenicity of the grafts. However, a small portion of cells in human femoral heads treated by standard bone-bank freezing procedures survive, thus limiting the effectiveness of allografts. Here, we characterized the survival rates and mechanisms of cells isolated from rat bones and tendons that were subjected to freeze-thaw treatments, and eva...

Huntington's Disease

Huntington's disease is a hereditary disease caused by a defect in a single gene on Chromosome 4 that is inherited in an autosomal dominant fashion. The defect causes a part of DNA, called a CAG...

Checkpoint kinase 1 CHK 1

Progression through the cell cycle is monitored by surveillance mechanisms known as cell cycle checkpoints. Dysfunction in cell cycle checkpoints leads to genomic instability and contributes to tumo...

Polo like kinase Plk 1

Polo-like kinase (Plk) is an important cell cycle regulatory kinase that has been implicated in a multitude of cell cycle events. Plks form a family of four different proteins that regulates many as...

Novel Mitotic Kinase Inhibitors

Mitosis, a central event in tumor growth, is highly regulated to ensure accurate and equal segregation of genetic materials from parent cells to daughter cells. Main effectors of this process are mi...
