A nose-only inhalation toxicity chamber capable of testing inhalation toxicity at four different exposure concentrations was designed and validated for flow field uniformity and cross-contamination between the exposure ports for each concentration. Here, we present a protocol to confirm that the designed chamber is effective for inhalation toxicity testing.

2013
The in ovo chorioallantoic membrane (CAM) is grafted with fresh sarcoma-derived tumor tissues, their single cell suspensions, and permanent and transient fluorescently labeled established sarcoma cell lines. The model is used to study graft- (viability, Ki67 proliferation index, necrosis, infiltration) and host (fibroblast infiltration, vascular ingrowth) behavior.

Studying RNA Interactors of Protein Kinase RNA-Activated during the Mammalian Cell Cycle

We present experimental approaches for studying RNA-interactors of double-stranded RNA binding protein kinase RNA-activated (PKR) during the mammalian cell cycle using HeLa cells. This method utilizes formaldehyde to crosslink RNA-PKR complexes and immunoprecipitation to enrich PKR-bound RNAs. These RNAs can be further analyzed through high-throughput sequencing or qRT-PCR.
FAQs
CKAP2 reflects a cytoskeleton-associated role in mitotic spindle organization and chromosome segregation, linking it to specific events during cell division. Ki-67 provides a broader indication of active cell-cycle participation because it is expressed during active phases but largely absent from resting cells. Examining both markers can therefore distinguish overall cycling activity from mitosis-related cellular behavior.
The two markers capture complementary aspects of proliferation rather than relying on a single cellular feature. Ki-67 indicates the presence of actively cycling cells, while CKAP2 relates to mitotic organization and chromosome segregation. Their combined assessment can support investigation of cell-cycle regulation and help researchers examine whether proliferative activity is associated with tumor growth characteristics.
Ki-67 is expressed during active phases of the cell cycle and is largely absent from resting cells. This contrast allows tissue analyses to estimate the proportion of cells participating in proliferation rather than simply counting cells present in a tumor. In cancer research, that distinction supports comparisons of proliferative activity among tumor samples or experimental groups.
A typical evaluation uses immunohistochemical analysis of tumor tissue to detect CKAP2 and Ki-67. The resulting staining patterns or marker measurements are then interpreted as indicators of proliferative activity and considered alongside pathological assessment. Measuring both markers in comparable tissue samples enables researchers to examine differences among tumors, cancer types, or treatment groups.
Marker measurements can support comparisons of proliferative activity across different tumor types or between treatment groups. Researchers may use the results to characterize how actively tumor cells are dividing and to examine whether groups differ in patterns associated with tumor growth. These comparisons complement pathological assessment rather than replacing the broader evaluation of tumor tissue.
CKAP2 and Ki-67 measurements can be incorporated into studies of tumor aggressiveness and potential prognostic relationships. Higher or lower proliferative patterns may be examined alongside pathological findings to identify associations with tumor growth characteristics. Such analyses are investigative: the markers help researchers evaluate relationships between cell-cycle activity and clinical or pathological features without independently establishing a prognosis.
