Evidence of Chromosomal Instability in Prostate Cancer Determined by Spectral Karyotyping (SKY) and Interphase FISH Analysis

Neoplasia: An International Journal for Oncology Research, 2001
The way in which cytogenetic aberrations develop in prostate cancer (Cap) is poorly understood. Spectral karyotype (SKY) analysis of Cap cell lines has shown that they have unstable karyotypes and also have features associated with chromosomal ...

Efficient haploid production on 'Wilking' mandarin by induced gynogenesis [PDF]

, 2015
Seedlessness is a major criterion for the citrus fresh fruit market. Therefore, triploid breeding appears very promising for the selection of new citrus cultivars.

Hybridization, polyploidy, and evolutionary transitions between monoecy and dioecy in Bryonia (Cucurbitaceae) [PDF]

, 2008
Correns’s 1903 (Berichte der Deutschen Botanischen Gesellschaft 21: 133 – 147) crosses between a monoecious and a dioecious species of Bryonia revealed the simple Mendelian inheritance of dioecy and provided the first instance of an XY sex determination ...

A Rare Hematopoietic Stem Cell‐Derived Megakaryocyte Progenitor Accumulates via Enhanced Survival and Contributes to Exacerbated Thrombopoiesis Upon Aging

Aging Cell, EarlyView.
Manso et al. developed strategies for isolating and testing the functional mechanisms regulating age‐specific megakaryocyte progenitors derived from hematopoietic stem cells. ABSTRACT Distinct routes of cellular production from hematopoietic stem cells (HSCs) have defined our current view of hematopoiesis.

Fluconazole-Induced Ploidy Change in Cryptococcus neoformans Results from the Uncoupling of Cell Growth and Nuclear Division

mSphere, 2017
Cryptococcus neoformans is a pathogenic yeast that causes lethal cryptococcal meningitis in immunocompromised patients. One of the challenges in treating cryptococcosis is the development of resistance to azole antifungals.

The Effect of Assisted Reproductive Technologies on Human Sex Ratios

Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.

Sexual conflict as a constraint on asexual reproduction: an empirical review

Biological Reviews, EarlyView.
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Effects of ploidy level on leaf morphology, stomata, and anatomical structure of Hibiscus syriacus L.

BMC Plant Biology
Background Hibiscus syriacus L. is a deciduous shrub with a strong environmental resistance and wide application prospects. The genetic background and ploidy levels of Hibiscus cultivars are complex, and polyploid breeding has long been an important ...
