"You could only be guaranteed that a man is infertile if he has no sperm in his ejaculate... [Conversely] you could have perfectly normal looking sperm, number, shape, motility, and so on, but if they can't penetrate the egg, then you would still be infertile".
Like other organelles, lysosomes require a careful balance of plus-end- versus minus-end-directed motility, and so motor recruitment is likely to be complex and tightly regulated (Akhmanova and Hammer, 2010; Holzbaur and Goldman, 2010).
Tumors from other origins were generally difficult to palpate, so other fitness markers (weight loss, skin condition, motility, and so on) were used to decide when to sacrifice an animal.
The induction of EMT in cancer cells may enhance their cell motility and invasiveness so that to facilitate the development of metastasis [13], [36].
Are significant abnormalities of CatSper function present in IVF patients with normal sperm concentration and motility and if so what is their functional significance for fertilization success?
Loss of reservoir function of the stomach, dysphagia, dyspepsia, altered intestinal motility, malabsorption and so-called 'gastric dumping syndrome' have been offered as explanations for the weight loss.
Its inferred motility, and even more so its association with the centrosome and primary cilium also insinuate some utility.
While this appears to be a very large proportion of the genome differentially regulated, this is not unexpected as the HI growth phase includes growth, development, genome replication and cell division whilst the attack phase is a much more specialised, non-replicative phase of motility and prey location and so the genes required for these stages are likely to be very different.
Most commonly, the output domain comprises a DNA-binding and transcription regulator function, leading to phenotypic changes in motility, growth, morphology, metabolism and so on.
Phospholipase C- γ 1 PLC- γ1), a very important member of phospholipase C PLCC) families, is upregulated in many cancer tissues and cancer cell lines and has been found to participate in many physical processes such as cell proliferation, motility, differentiation, cytoskeleton rearrangement and so forth.
Thus, if flagella were important for colonization, and motility less so, a motAB mutant might not be affected in colonization.
