In epithelial ovarian cancer cells, platinum favours binding and phosphorylation of FOXO3 by the CDK6/cyclin D3 complex. FOXO3 is thus stabilized and binds the ATR promoter thereby inducing its transcription and preventing platinum‐induced cell death.
Synopsis
In epithelial ovarian cancer cells, platinum favours binding and phosphorylation of FOXO3 by the CDK6/cyclin D3 complex. FOXO3 is thus stabilized and binds the ATR promoter thereby inducing its transcription and preventing platinum‐induced cell death.
CDK6 in complex with cyclin D3 participates in the control of DNA damage response.
CDK6 binds and phosphorylates FOXO3 on serine 325 to control ATR expression.
High CDK6 expression predicts poor survival of EOC patients.
A combination of platinum‐based chemotherapy with pharmacological CDK6 inhibition might be a new therapeutic option for EOC patients.

The hypothesis is discussed that prostate cancer marker lncRNA PCA3 was introduced into the human genome by an oncogenic virus, and that viral infection‐related mechanisms might underlie its overexpression and prostate cancer initiation and/or progression.

SPINK2, a serine protease inhibitor, is believed to target the acrosin, the main sperm acrosomal protease. This study confirms SPINK2 in that role and finds it essential for spermiogenesis as SPINK2 deficiency induces a post meiotic block at the round spermatid stage leading to azoospermia in mice and men.
Synopsis
SPINK2, a serine protease inhibitor, is believed to target the acrosin, the main sperm acrosomal protease. This study confirms SPINK2 in that role and finds it essential for spermiogenesis as SPINK2 deficiency induces a post meiotic block at the round spermatid stage leading to azoospermia in mice and men.
In round spermatids, SPINK2 is necessary to inactivate the acrosin during its transit through the endoplasmic reticulum and the Golgi apparatus.
In the absence of SPINK2, acrosin can auto‐activate, disorganize the Golgi apparatus, prevent the production of the acrosome and induce a block at the round spermatid stage.
A reduced amount of SPINK2 in heterozygotes is also deleterious, inducing a milder phenotype of oligozoospermia and/or teratozoospermia without a systematic infertility.

Vaccinia virus (VACV) mutated to render it incapable of synthesizing deoxynucleoside triphosphates (dNTPs) is a safe, highly selective, and potentially superior oncolytic agent in animal models for bladder cancer.
Synopsis
Vaccinia virus (VACV) mutated to render it incapable of synthesizing deoxynucleoside triphosphates (dNTPs) is a safe, highly selective, and potentially superior oncolytic agent in animal models for bladder cancer.
F4L‐deleted VACVs are highly attenuated in normal tissues and selectively replicate in, and kill bladder cancer cells that express elevated RRM2 levels.
F4L‐deleted VACVs replicate selectively in immune‐competent rat AY‐27 and xenografted human RT112‐luc orthotopic bladder cancer models, causing significant tumor regression or complete ablation with no toxicity.
Rats cured of AY‐27 tumors by VACV treatment developed long‐lasting anti‐tumor immunity.
F4L‐deleted VACVs replicate in primary human bladder cancer explants and BCG‐resistant cell lines.

Angiomyolipoma (AML) research is hampered by the lack of an animal model. In a novel in vivo human AML model, PPARG inhibition is identified as a potential therapy and the AML cell of origin as a resident MSC/pericyte skewed toward adipogenic differentiation.
Synopsis
Angiomyolipoma (AML) research is hampered by the lack of an animal model. In a novel in vivo human AML model, PPARG inhibition is identified as a potential therapy and the AML cell of origin as a resident MSC/pericyte skewed toward adipogenic differentiation.
An AML xenograft (Xn) model, exhibiting the classic histology, immunophenotype, and gene expression pattern of human AML, was established by injection of human AML cells in mice.
AML Xn propagation in vivo is accompanied by robust activation of the PPARG pathway, and human AML tumors strongly express PPARG.
PPARG is expressed across all tumor compartments, indicating that rather than accompanying adipocytic differentiation, PPARG activation drives AML growth, and with the presence of fat in the tumor being its by‐product.
PPARG antagonism, via small molecules and shRNA, results in strong growth inhibition of AML, as well as abrogation of tumor initiation in mice.
Human AML cells exhibit striking similarity to human MSCs, in terms of gene expression, surface marker expression, and potential.

VEGFA is not only a key mediator of angiogenesis during tumor progression, but can also act to expand the population of ovarian cancer‐initiating cells with stem‐like properties.
Synopsis
VEGFA is not only a key mediator of angiogenesis during tumor progression, but can also act to expand the population of ovarian cancer‐initiating cells with stem‐like properties.
VEGFA increases sphere formation and ALDH1 activity of ovarian cancer cells in vitro and stimulates ovarian tumor‐initiating cells in vivo.
VEGFA rapidly activates VEGFR2 and Src to upregulate DNMT3 expression.
DNMT3A plays a pro‐oncogenic role to methylate miR‐128‐2 leading to Bmi1 and OVCA stem‐like cell upregulation.
High VEGFA and decreased miR‐128‐2 associate with poor ovarian cancer outcome.

CLU silencing sensitizes prostate cancer cells to taxane by inducing a constitutive activation of Cdc25C leading to a delay in exit from mitosis. In response, cells up‐regulate protective mechanisms through Wee1 kinase.
Synopsis
CLU silencing sensitizes prostate cancer cells to taxane by inducing a constitutive activation of Cdc25C leading to a delay in exit from mitosis. In response, cells up‐regulate protective mechanisms through Wee1 kinase.
CLU expression and Cdc25C expression are negatively correlated in prostate cancer cell lines, mice xenografts, and human biopsies.
CLU silencing induces accumulation of Cdc25C‐T48 phosphorylation.
Constitutive activation of Cdc25C by CLU silencing is compensated by Wee1 up‐regulation.
CLU silencing sensitizes PC3 cells to cabazitaxel, and inhibition of Wee1 improves synergistic responses to combination of taxanes and CLU inhibitors.

Self‐limited delayed puberty (DP) has strong familial inheritance, but the underlying genetic determinants are unknown. IGSF10 deficiency is found to affect embryonic GnRH neuronal migration and results in DP in humans.
Synopsis
Self‐limited delayed puberty (DP) has strong familial inheritance, but the underlying genetic determinants are unknown. IGSF10 deficiency is found to affect embryonic GnRH neuronal migration and results in DP in humans.
Pathogenic mutations in IGSF10 are found in patients with self‐limited delayed puberty.
IGSF10 is a gene of previously unclear function with no known human mutations.
IGSF10 is expressed within the nasal mesenchyme during fetal development, in a pattern similar to known chemokines that direct migrational GnRH neurons to the hypothalamus.
Knockdown of IGSF10 led to a reduced migration of GnRH neurons in vitro and in a transgenic zebrafish model.
IGSF10 loss‐of‐function mutations were also identified in patients with hypothalamic amenorrhea, suggesting an overlapping genetic and mechanistic basis between different types of functional hypogonadotropic hypogonadism, including DP and hypothalamic amenorrhea.

To maximise in vitro fertilization success rate, the embryo prioritized for transfer must be the most capable within the cohort of embryos generated by the patient. The blastocentesis procedure described here could be a way to get there.
Synopsis
To maximise in vitro fertilization success rate, the embryo prioritized for transfer must be the most capable within the cohort of embryos generated by the patient. The blastocentesis procedure described here could be a way to get there.
Blastocentesis is a novel micromanipulation technique used to collect a 4 nL sample of blastocoelic fluid from living human embryos.
A catalogue of 182 proteins secreted by the human blastocyst and validated by microarray gene expression analysis of whole human embryo is provided.
Targeted mass spectrometry approach enables the measurement of nine proteins of interest from single human blastocoels.
Blastocentesis has no long‐term impact on embryo overall architecture, suggesting its potential application in a clinical setting.
