Summary: Inhibiting or deleting members of the P21-activated kinases (PAKs) family can impact cell metabolism, influencing mitochondrial respiration and aerobic glycolysis rates. Specifically, downregulation of PAK2 is linked to oxidative phosphorylation, while knockout of PAK1 results in increased glycolysis. Despite these changes, the overall metabolic capacity is not substantially reduced, possibly due to redundancy or compensatory mechanisms within the PAK1/PAK2 regulatory roles.

Summary: Ovarian cancer preferentially metastasizes in association with mesothelial cell-lined surfaces. The presence of mesothelial cells is required for ovarian cancer metastasis, and the interaction between mesothelial cells and ovarian cancer cells leads to alterations in gene expression and cytokine secretion. The secretion of ANGPTL4 by mesothelial cells promotes ovarian cancer metastasis through various mechanisms.

Summary: XIST and FOXP3 were upregulated, while miR-149-3p was downregulated in OC tissues and cells. High XIST expression indicated a poor prognosis for OC. Inhibition of XIST or elevation of miR-149-3p suppressed malignant behaviors of OC cells, such as proliferation, invasion, migration, and colony formation, and promoted apoptosis and cell cycle arrest. This study suggests that knockdown of XIST increases miR-149-3p expression to inhibit OC development.

Summary: In this study, quantitative phosphoproteomics characterization of ccRCC tumor and normal adjacent tissues revealed significant differential regulation of phosphoproteins between tumor and normal tissues. These differentially regulated phosphoproteins are associated with proliferative and migratory behavior of renal tumors. Furthermore, master kinases responsible for phosphorylation of substrates associated with cell proliferation, inflammation, and migration were identified.

Summary: This study reveals a new role for Pak1 in regulating cell shape through its association with the RNA-binding protein Sts5 and P bodies. Pak1 plays a key role in preventing Sts5 from associating with P bodies and promotes rapid dissolution of Sts5 during glucose addition by localizing to stress granules.

Summary: This study established an invasion-related multigene signature to predict the prognostic risk of ovarian cancer. A 6-gene prognostic risk model was constructed and shown to be independent of clinical features. This signature has the potential to evaluate the prognostic risk of ovarian cancer patients.

Summary: PDP1 is overexpressed in ovarian cancer tissues and is associated with poor prognosis and worse clinical parameters. In vitro experiments show that PDP1 promotes cell proliferation, invasion, and migration in ovarian cancer cells. GSEA analysis reveals that the IL6/JAK/STAT3 signaling pathway, interferon-alpha response, apoptosis, adipogenesis, KRAS signaling, and IL2/STAT5 signaling are activated in ovarian cancer patients with high PDP1 expression. Drug sensitivity analysis demonstrates a negative correlation between PDP1 expression and the IC50 of bleomycin and gemcitabine, indicating that high PDP1 expression may lead to increased sensitivity to these drugs and decreased sensitivity to cisplatin. PDP1 plays a role in ovarian cancer progression and is a potential biomarker for patient prognosis and chemosensitivity.

Summary: S1PR1 was found to be highly expressed in human ovarian cancer tissues and cells, and its deletion inhibited cancer cell proliferation and migration while promoting cell senescence and sensitivity to chemotherapy. S1P was shown to regulate ovarian cancer cell senescence by modulating the expression of PDK1, LATS1/2, and YAP. The study demonstrates the importance of the S1PR1-PDK1-LATS1/2-YAP signaling axis in the regulation of ovarian cancer cell senescence.

Summary: This study aimed to assess the association between PAK1 gene copy number and proliferation status, molecular subtype, and prognosis in breast cancer. The results showed that PAK1 copy number increase is associated with high proliferation and high histological grade, but not with prognosis. PAK1 copy number increase is most frequent in the HER2 type and Luminal B (HER2(-)) subtype and is associated with CCND1 copy number increase.

Summary: Salt-inducible kinase 2 (SIK2) is overexpressed in ovarian cancer and promotes cancer cell motility and metastasis through the regulation of myosin light chain kinase. Adipocytes induce the phosphorylation of SIK2 and myosin light chain kinase, enhancing the migration of ovarian cancer cells. The expression of SIK2 is positively correlated with MYLK-pS343 and is associated with reduced overall survival in ovarian cancer patients. SIK2 could be a potential candidate for ovarian cancer treatment.

Summary: This study found that cell fusion may be involved in the formation of ovarian PGCCs, and this process is promoted by paclitaxel and UPR activation. Modulating the UPR could be an interesting therapeutic strategy to prevent the formation of PGCCs and therefore limit cancer relapse and drug resistance.

Summary: In ovarian cancer patients, TMEM119 is overexpressed and associated with poor survival. Experimental results indicate TMEM119 promotes proliferation, invasion, and migration of ovarian cancer cells. Additionally, TMEM119 may exert oncogenic effects by regulating PDGFRB expression and activating the PI3K/AKT signaling pathway.

Summary: A retrospective review of tamoxifen use in patients with advanced or recurrent ovarian cancer showed a clinical benefit rate of 56% and a median progression-free survival of 5.3 months. Patients tolerated tamoxifen well, and hormone receptor status was not predictive of response. Tamoxifen may still have a role in the era of molecular target therapy for these patients.

Summary: Balanced chromosomal abnormalities (BCAs) are changes in chromosomal segments without genetic material gain or loss, occurring in 1 in 500 newborns and associated with increased risk of congenital anomalies and neurodevelopmental disorders. Using short read genome sequencing (GS) for diagnosing BCAs can provide more specific genetic diagnosis information, potentially improving genetic counseling and perinatal management.

Summary: The incidence of discordant fetal sex is estimated to be 1 in 1500-2000, requiring comprehensive evaluation. Chimera is identified as one of the possible causes of genotype-phenotype sex discordance, detectable prenatally through a combination of noninvasive prenatal screening and ultrasound. Genetic counseling for prospective parents on chimera may be complex, necessitating early support and information from experienced professionals.

Summary: Beckwith-Wiedemann Syndrome (BWS) is an imprinting disorder characterized by a range of prenatal features. Paternal uniparental disomy in chromosome 11p15 imprinting region is a common cause of BWS, while genome-wide paternal uniparental disomy (GWpUPD) is rare and typically results in prenatal lethality. We reported two prenatal cases initially presenting with BWS features, which were confirmed to have GWpUPD. SNP genotyping analysis revealed androgenetic biparental chimera as the underlying cause.

Summary: The study demonstrates the utility of whole-exome sequencing (WES) in prenatal diagnosis of fetal structural congenital abnormalities (SCAs) in Hong Kong. The highest diagnostic rate was found in fetuses with multiple SCAs, particularly involving the cardiac and musculoskeletal systems. The use of WES should be recommended in addition to conventional genetic workup.

Summary: Schuurs-Hoeijmakers syndrome (SHS) is a rare syndrome caused by a de novo variant in the PACS1 gene. It is characterized by typical facial features, developmental delay, intellectual disability, and multiple malformations, with distinct diagnostic features before and after birth. Use of exome sequencing has aided in diagnosing SHS and expanding the understanding of the clinical phenotype associated with pathogenic PACS1 variants.
