A gene for human proliferating cell nucleolar protein p120 has been isolated from a human genomic library using p120 cDNA as a probe. The gene spanned 12 kilobase pairs and was composed of 15 exons and 14 introns. Unusual splice junction sequences, (AT) and (AC), instead of (GT) and (AG), respectively, were located at the splice sites for intron F. The 5' flanking region was analyzed for putative cis-acting factor binding sites. The region contained a TATA-like sequence and the CCAAT box. CAT assays indicated that the region -2532 /+ 102 was necessary for transcription. Two specific areas at -1444/-1224 and -537/-278 were shown to be important for transcription. Two "GC" boxes and two "GC"-rich sequences were observed Other sites upstream of these sites were analyzed for homology to other gene control regions.

Exosomes are nanoscale extracellular vesicles with various biological activities that can accelerate wound healing by regulating inflammatory responses, promoting cell proliferation and angiogenesis, and other mechanisms. Among them, plant and animal exosomes have demonstrated unique advantages due to their biological characteristics. Plant exosomes have gradually become a research hotspot due to their wide source, high biosafety, and low production cost, demonstrating significant pro-healing potential.

Despite being designated as "noncarcinogenic" human papillomavirus (HPV) types, mono-infection with HPV6 or HPV11 has been found in squamous cell carcinomas (SCCs) at specific sites, including the larynx, penis, anus, and rarely, the lower female genital tract. The association between clinicopathologic features, viral status, and the carcinogenic mechanisms related to these low-risk HPVs remains unclear. The current study characterizes a series of low-risk HPV6 and HPV11-associated SCCs of the uterine cervix (6 cases) and vulva (2 cases).

The purpose of this study is to evaluate the optimum frequency of oscillatory fluid flow (OFF) for increasing osteogenesis in human dental pulp cells (DPCs) in an incubating rocking shaker. DPCs from 3 donors were cultured in an osteogenic induction medium (OIM) and mechanical stimulation was applied using an incubating rocking shaker at frequencies of 0 (control), 10, 20, 30, and 40 round per minute (RPM) for 1 h/day, 5 days/week. Cell proliferation was measured using total protein quantification, and osteogenic activity was measured by alkaline phosphatase (ALP) activity, calcium deposition, and collagen production on days 7, 14, and 21 of culture.

They consist of arteriovenous shunts, without cellular hyperplasia or proliferation, which develop in the surrounding tissues (cutaneous, subcutaneous, muscular, bone). Although benign, they are among the most severe of superficial malformations.

Background: Drug resistance constitutes one of the principal causes of poor prognosis in breast cancer patients. Although cancer cells can maintain viability independently of mitochondrial energy metabolism, they remain reliant on mitochondrial functions for the synthesis of new DNA strands. This dependency underscores a potential link between mitochondrial energy metabolism and drug resistance.
