Comparative Studies on X-autosome Translocations
nine X-autosome translocations observed in the mouse possess distinctive T y f t u r e s that give each certain advantages and certain disadvantages in studies of gene action connected with X-chromosome inactivation. Thus, for T (X; ?) 16H, the translocation reported by SEARLE (1962), both genetic (LYON, SEARLE, FORD and OHNO 1964) and cytological ( OHNO and LYON 1965) evidence indicates that X...
متن کاملMuscular dystrophy in girls with X;autosome translocations.
Twenty known cases of X;autosome translocations with breakpoints at Xp21 associated with Duchenne or Becker muscular dystrophy in girls are reviewed. The variable severity described for different persons may reflect differences in X inactivation or in the nature of the genomic target disrupted. High resolution cytogenetic studies on 12 cases indicate breakpoints on the X chromosome at Xp21.1 or...
متن کاملHypomelanosis of Ito and X;autosome translocations: a unifying hypothesis.
Hypomelanosis of Ito is a sporadic multisystem disorder known to be associated in many cases with chromosomal mosaicism. While no particular pattern is generally evident for the specific chromosomes involved in such patients, a subgroup of female patients exists in whom the common factor is the presence of a balanced, constitutional X;autosome translocation, with a cytogenetic breakpoint in the...
متن کاملCharacterization of the testicular regeneration potential in premature cockerels
Previous studies have shown that grafted neonatal chicken testicular tissue can develop and produce functional sperm; however, it was unclear whether regenerative processes or proportional growth caused the re-appearance of spermatogenic tissue. We dissociated testicular tissues, performed subcutaneous auto-transplantation of the re-aggregated cells to castrated cockerels, and monitored the pos...
متن کاملMicrodissection testicular sperm extraction
Microdissection testicular sperm extraction (microTESE) is considered the gold standard method for surgical sperm retrieval among patients with non-obstructive azoospermia (NOA). In this review, we will discuss the optimal evaluation of NOA patients and strategies to medically optimize NOA patients prior to microTESE. In addition, we will also discuss technical principles and pearls to maximize...
