Role of SYT11 in human pan-cancer using comprehensive approaches.

Background: Synaptotagmin 11 (SYT11) plays a pivotal role in neuronal vesicular trafficking and exocytosis. However, no independent prognostic studies have focused on various cancers. In this study, we aimed to summarize the clinical significance and molecular landscape of SYT11 in various tumor types.

In vitro Fertilization Outcomes of Frozen-thawed Embryo Transfer with Hatched Blastocysts versus with Hatching Blastocysts.

This study aimed to elucidate the effect of hatching status on in vitro fertilization (IVF) outcomes in frozen-thawed blastocyst transfer cycles. Frozen-thawed embryo transfer (FET) cycles performed at a single fertility center between 2016 and 2021 were retrospectively assessed. Analyses were restricted to 6,821 frozen-thawed blastocyst transfers in women aged 24-47 years.

The LKB1-TSSK1B axis controls YAP phosphorylation to regulate the Hippo-YAP pathway.

The Hippo pathway's main effector, Yes-associated protein (YAP), plays a crucial role in tumorigenesis as a transcriptional coactivator. YAP's phosphorylation by core upstream components of the Hippo pathway, such as mammalian Ste20 kinase 1/2 (MST1/2), mitogen-activated protein kinase kinase kinase kinases (MAP4Ks), and their substrate, large tumor suppressor 1/2 (LATS1/2), influences YAP's subcellular localization, stability, and transcriptional activity. However, recent research suggests the existence of alternative pathways that phosphorylate YAP, independent of these core upstream Hippo pathway components, raising questions about additional means to inactivate YAP.

Ubiquitin E3 ligases in cancer: somatic mutation and amplification.

Defects in DNA double-strand break (DSB) repair signaling permit cancer cells to accumulate genomic alterations that confer their aggressive phenotype. Nevertheless, tumors depend on residual DNA repair abilities to survive the DNA damage induced by genotoxic stress. This is why only isolated DNA repair signaling is inactivated in cancer cells.

Effect of different ceramic materials and substructure designs on fracture resistance in anterior restorations.

Statement Of Problem: Materials have been developed to reduce the chipping of ceramic veneer and improve the esthetics of anterior ceramic veneered restorations. However, studies of the effects of material and substructure design on fracture resistance are sparse.

Purpose: The purpose of this in vitro study was to investigate the fracture resistance of metal-ceramic (MC), zirconia-feldspathic porcelain (ZC), and zirconia-lithium disilicate (ZL) anterior restorations and evaluate the effect of material and substructure design.

A comparison of surgical outcomes between robot and laparoscopy-assisted adenomyomectomy.

We aimed to investigate the feasibility of robotic adenomyomectomy and compared surgical outcomes between laparoscopic and robotic approaches for adenomyomectomy.We retrospectively reviewed the data of women who were diagnosed with adenomyosis and underwent adenomyomectomy through a minimally invasive approach between January 2014 and March 2018 at the CHA Gangnam Medical Center, Seoul, Republic of Korea. Patient demographics and operation-related outcomes were compared between the robotic and laparoscopic surgery groups.

Effect of liners and primers on tensile bond strength between zirconia and resin-based luting agent.

Purpose: The effect of silica-based glass-ceramic liners on the tensile bond strength between zirconia and resin-based luting agent was evaluated and compared with the effect of 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-containing primers.

Materials And Methods: Titanium abutments and zirconia crowns (n = 60) were fabricated, and the adhesive surfaces of the specimens were treated by airborne-particle abrasion. The specimens were divided into 5 groups based on surface treatment: a control group, 2 primer groups (MP: Monobond Plus; ZP: Z Prime Plus), and 2 liner groups (PL: P-containing Liner; PFL: P-free Liner).

LRRK2 functions as a scaffolding kinase of ASK1-mediated neuronal cell death.

Leucine-rich repeat kinase 2 (LRRK2), a multi-domain protein, is a key causative factor in Parkinson's disease (PD). Identification of novel substrates and the molecular mechanisms underlying the effects of LRRK2 are essential for understanding the pathogenesis of PD. In this study, we showed that LRRK2 played an important role in neuronal cell death by directly phosphorylating and activating apoptosis signal-regulating kinase 1 (ASK1).

Parkin mediates neuroprotection through activation of Notch1 signaling.

Parkin, an E3 ubiquitin ligase, is the most frequently mutated gene in hereditary Parkinson's disease. Inactivation of Parkin leads to impairment of the ubiquitin-proteasome system, resulting in the accumulation of misfolded or aggregated proteins and ensuing neurodegeneration. In this study, we show that Parkin positively regulates the Notch1 signaling pathway.

Autophagy negatively regulates tumor cell proliferation through phosphorylation dependent degradation of the Notch1 intracellular domain.

Autophagy is a highly conserved mechanism that degrades long-lived proteins and dysfunctional organelles, and contributes to cell fate. In this study, autophagy attenuates Notch1 signaling by degrading the Notch1 intracellular domain (Notch1-IC). Nutrient-deprivation promotes Notch1-IC phosphorylation by MEKK1 and phosphorylated Notch1-IC is recognized by Fbw7 E3 ligase.

NOTCH1 intracellular domain negatively regulates PAK1 signaling pathway through direct interaction.

p21-Activated kinase 1 (PAK1) is a serine/threonine protein kinase implicated in cytoskeletal remodeling and cell motility. Recent studies have shown that it also promotes cell proliferation, regulates apoptosis, and increases cell transformation and invasion. In this study, we showed that NOTCH1 intracellular domain (NOTCH1-IC) negatively regulated PAK1 signaling pathway.

Fe65 negatively regulates Jagged1 signaling by decreasing Jagged1 protein stability through the E3 ligase Neuralized-like 1.

Fe65 is a highly conserved adaptor protein that interacts with several binding partners. Fe65 binds proteins to mediate various cellular processes. But the interacting partner and the regulatory mechanisms controlled by Fe65 are largely unknown.

Alpha-synuclein negatively regulates Notch1 intracellular domain protein stability through promoting interaction with Fbw7.

Notch signaling pathway is well known that it is involved in regulating cell fate, proliferation and homeostasis. In this study, we show a novel function of alpha-synuclein (SNCA) to promote degradation of Notch1 intracellular domain (Notch1-IC) through Fbw7, ubiquitin E3 ligase. We identified that SNCA inhibits Notch1 transcription activity and diminishes the interaction between Notch1-IC and RBP-Jk.

Akt1 phosphorylates Nicastrin to regulate its protein stability and activity.

The gamma-secretase is a multiprotein complex that cleaves many type-I membrane proteins, such as the Notch receptor and the amyloid precursor protein. Nicastrin (NCT) is an essential component of the multimeric gamma-secretase complex and functions as a receptor for gamma-secretase substrates. In this study, we found that Akt1 markedly regulated the protein stability of NCT.

Efficacy of sulforaphane is mediated by p38 MAP kinase and caspase-7 activations in ER-positive and COX-2-expressed human breast cancer cells.

Sulforaphane is an antioxidant and a potent stimulator of natural detoxifying enzyme and associated with lowered risk of cancer that is associated with the consumption of cruciferous vegetables. The chemopreventive effects of SFN was investigated using the MCF-7 human breast cancer cells and the M13SV1-immortalized human breast luminal epithelial cells. Sulforaphane reduced proliferation in MCF-7 cells and inhibited cyclooxygenase-2 expression in M13SV1 cells treated with 12-O-tetradecanoylphorbol-13-acetate (TPA).

Induction of apoptosis in MCF-7 and MDA-MB-231 breast cancer cells by Oligonol is mediated by Bcl-2 family regulation and MEK/ERK signaling.

Oligonol is a novel catechin-rich biotechnology product. The role of oligonol in modulating intracellular signaling mechanisms was investigated with the view of demonstrating its potential chemopreventive effect and the ability to inhibit cell proliferation using the estrogen-responsive MCF-7 and the estrogen-unresponsive MDA-MB-231 human breast cancer cell lines. Cell survival assay indicated that Oligonol was cytotoxic to both cells.
