Tissue Microarrays stained for "Anti-Ki67 antibody [SP6]” using "ab16667" at 1/200 dilution (0.145 μg/ml) in immunohistochemical analysis. This table provides a detailed overview of positive (tick mark) and negative (cross mark) staining per sample type tested. Taking human colon tissue as an example, Ki67 is barely expressed or the expression level is very low in normal colon tissue, and the IHC test result is usually negative. While the expression of Ki67 can be upregulated in the proliferating cells of colon tissue, and the IHC test result could be positive. The sections were pre-treated using Heat mediated antigen retrieval using ab93678 (citrate buffer, pH 6.0). The sections were incubated with ab16667 at +4°C overnight followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP polymer) (ab214880). Hematoxylin was used as the counter stain.

In Western blot, ab16667 was shown to bind specifically to MKI67. A band was observed at 359 kDa in wild-type A549 cell lysates with no signal observed at this size in MKI67 knockout cell line. To generate this image, wild-type and MKI67 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

特異性

Ki67 is mainly expressed in proliferating cells. For normal tissue samples (e.g., liver, kidney), no staining may be typically observed due to low level of proliferation and little expression of Ki67. For malignant tissue samples (e.g., colon carcinoma, breast carcinoma), it is more easily to find Ki67 in the proliferating cells of these tissues (PMID: 6206131, 10653597, 34183782).

Ki-67 is a protein that serves as a marker for cell proliferation in oncology. It is widely used to assess the growth rate of cancer cells, helping to determine the aggressiveness of tumors and guide treatment decisions. High levels of Ki-67 are often associated with more aggressive cancers and poorer prognosis

補足情報

Ki67 is a nuclear protein often referred to as MKI67 with a molecular weight of approximately 345 kDa. This protein is strongly associated with cell proliferation. Scientists commonly use Ki67 staining techniques to identify and quantify proliferating cells in tissues. Ki67 is expressed in the nucleus during active cell cycle phases—G1 S G2 and M—but not in resting cells in G0 phase. It is detectable through methods such as Ki67 immunofluorescence and Ki67 flow cytometry which are important for analyzing cell division.
Biological function summary

The Ki67 protein plays an essential role in cellular proliferation processes. It does not form part of a stable complex but interacts transiently with other cell cycle-related proteins. Research indicates that Ki67 maintains the structure of the perichromosomal layer during mitosis impacting chromosome separation. It is particularly active in tissues with high cell turnover such as bone marrow and lymphoid organs.

Pathways

Ki67 influences several key cellular pathways that control cell proliferation and differentiation. The protein acts within the regulation of the cell cycle and the PI3K/AKT signaling pathway important for cell growth and survival. Within these pathways Ki67 interacts with proteins like cyclin-dependent kinases (CDKs) which regulate transitions between different phases of the cell cycle.

Ki67 has significant implications in oncology and can be used as a biomarker for cancer prognosis. Its expression levels help determine the aggressiveness of tumors especially in breast cancer and prostate cancer. High Ki67 levels correlate with poor prognosis as it indicates rapid cell division. In cancer Ki67 associates with p53 a protein that regulates the cell cycle and function as a tumor suppressor.

ターゲットの情報

The protein expressed by the MKI67 gene is required to maintain individual mitotic chromosomes dispersed in the cytoplasm following nuclear envelope disassembly and associates with the surface of the mitotic chromosome, specifically the perichromosomal layer, covering a significant portion of the chromosome surface (PubMed : 27362226). It prevents chromosomes from collapsing into a single chromatin mass by creating a steric and electrostatic charge barrier due to its high net electrical charge, acting as a surfactant that disperses chromosomes and enables their independent motility (PubMed : 27362226). The protein binds DNA, with a preference for supercoiled and AT-rich DNA (PubMed : 10878551), and may play a role in chromatin organization, though it is unclear if it directly influences chromatin organization or if this is an indirect result of its function in maintaining dispersed mitotic chromosomes (Probable, PubMed : 24867636).
