[Genetic diversity and genetic structure of Sorex isodon in Northeast China].

A total of 64 haplotypes were obtained from the complete Cytochrome b gene (Cyt b) of 77 Sorex isodon collected from three populations (Daxing'anling, Xiaoxing'anling, and Changbai Mountains) in Northeast China. The haplotype diversity was 0.9920 and the nucleotide diversity was 0.

miR-125a Promotes the Progression of Giant Cell Tumors of Bone by Stimulating IL-17A and β-Catenin Expression.

Giant cell tumors of bone (GCTBs) exhibit high recurrence and aggressive bone lytic behavior; but, the mechanism of GCTB progression is largely unknown. In GCTB, we detected abundant levels of miR-125a, which were associated with tumor extension, grade, and recurrence. miR-125a stimulates stromal cell tumorigenicity and growth in vivo by promoting the expression of interleukin-17A (IL-17A) and β-catenin.

Sequencing and analysis of the complete mitochondrial genome of the taiga shrew () from China.

The complete mitogenome sequence of the taiga shrew () was determined using long PCR. The genome was 17,008 bp in length and contained 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, one origin of L strand replication and one control region. The overall base composition of the heavy strand is A (32.

A high risk of osteosarcoma in individuals who are homozygous for the p.D104N in endostatin.

The D104N polymorphism (p.D104N) in endostatin has been previously identified in many types of cancer, and this polymorphism is believed to be a phenotypic modulator in some tumors. However, it is unknown whether endostatin p.

[Proliferation of tissue-engineered cartilage cells under compressive stress].

Objective: To investigate the proliferation of tissue-engineered cartilage cells stimulated by different intensities of compressive stress.

Methods: Human embryonic cartilage cells were seeded into type II collagen sponge scaffold. The cells of the pressure groups were stimulated by different compression rate (0-5%, 0-10%, and 0-20%) at a cyclical frequency of 0.
