Summary: The endogenous L-carnitine and its derivative acetyl-L-carnitine play a role in antidepressant effects and may serve as potential biomarkers for diagnosing MDD. The levels of serum LC and ALC are significantly reduced in patients with MDD, with potential diagnostic value. Furthermore, changes in LC and ALC concentrations could differentiate between effective and ineffective treatment of depression, indicating their potential as novel biomarkers.

Summary: The study found that l-carnitine can reduce body mass in type 2 diabetes mellitus patients, while no significant effects were observed with acetyl-l-carnitine or propionyl-l-carnitine. To achieve 80% of the maximal effect, a minimum of 2 grams of l-carnitine daily for at least 2 weeks was required.

Summary: Mitochondrial oxidative phosphorylation (OXPHOS) is sensitive to various biological factors and dysregulation of OXPHOS is observed in the development of many pathological conditions. Acetyl-l-carnitine (ALCAR) is an endogenous source of acetyl-coenzyme A (CoA) and can be used to assess OXPHOS. In this study, hyperpolarized (HP) [1-C-13]ALCAR was developed as a noninvasive probe for investigating cardiac tricarboxylic acid (TCA) cycle activity in vivo. This study demonstrates the first use of HP methods with [1-C-13]ALCAR to analyze mitochondrial function and TCA cycle activity in the heart.

Summary: Cataract is a major cause of blindness for 17 million people worldwide, accounting for about 47.9% of vision loss cases. The formation of cataracts is related to the generation of reactive oxygen species (ROS) and the decrease of endogenous antioxidants. Natural antioxidant compounds found in plants can be effective preventatives and inhibitors for cataracts. Further research can explore the use of natural antioxidant extracts for cataract therapy.

Summary: This study found that patients with major depressive episodes have lower levels of peripheral acetyl-l-carnitine (ALC) and higher levels of l-carnitine compared to healthy controls. After antidepressant treatment, these imbalances are restored, and the severity of mitochondrial dysfunction may predict the response to treatment.

Summary: Growth differentiation factor 15 or macrophage inhibitory cytokine-1 (GDF15/MIC-1) is a divergent member of the transforming growth factor beta superfamily and has diverse pathophysiological roles in cancers, cardiometabolic disorders, and other diseases. Its role in cancer development and progression is complicated and depends on the specific cancer type and stage, and its mechanisms are related to its receptor GFRAL.

Summary: Cyclic nucleotide phosphodiesterases (PDEs) are a superfamily of enzymes that regulate the spatial and temporal relationship of second messenger signaling in the cellular system. The PDE1 sub-family consists of three subtypes with different affinities for cAMP and cGMP, and their catalytic activity is stimulated by binding to Ca2+/calmodulin, playing a critical role in various diseases.

Summary: Despite advancements in cancer diagnosis and treatment, high burden of cancer still remains a significant cause of morbidity and mortality. Cancer cell secretory factors, such as macrophage inhibitory cytokine-1 (MIC-1), play a crucial role in modulating the tumor microenvironment and supporting tumor growth. Understanding the molecular regulation and downstream signaling of MIC-1 in cancer is important for developing effective therapeutic approaches.

Summary: This study aimed to identify the molecular mechanism of liver metastasis in pancreatic ductal adenocarcinoma (PDAC) mediated by MUC16. The expression of MUC16 was significantly high in PDAC tissues, PDAC organoids, and metastatic liver tissues, while no expression was observed in normal pancreatic tissues. MUC16 knockdown decreased the colony formation, migration, and endothelial/p-selectin binding in PDAC cells, while ectopic overexpression of MUC16-Cter increased colony formation and motility in pancreatic cancer cells. MUC16 promoted cell survival and colonization in the liver and enhanced liver metastasis in a mouse model. The integrated analyses suggested that MUC16 regulates NRP2 and induces metastasis in PDAC via the JAK2/STAT1 signaling pathway.

Summary: Muc16 plays an oncogenic role in pancreatic ductal adenocarcinoma (PDAC). Deletion of Muc16 can decrease tumor progression and improve overall survival in mice models. Muc16 knockout reduces tumor microenvironment factors and incidence of liver and lung metastasis. Further research shows that Muc16 alters the expression of Actg2, Myh11, and Pdlim3 genes, affecting pancreatic cancer progression and metastasis.

Summary: We identified SNARE Sec22b as a critical regulator of plasma cell maintenance and function. In the absence of Sec22b, plasma cells were hardly detectable and serum antibody titers were dramatically reduced, leading to a failure in mounting a protective immune response. Mechanistically, Sec22b contributes to efficient antibody secretion and is involved in regulating plasma cell transcriptional identity, as well as the morphology of the endoplasmic reticulum and mitochondria.

This study assessed the effects of Pax6-haploinsufficiency on retinal morphology and vision in Pax6Sey mice. The results showed elevated intraocular pressure and declining visual acuity in Pax6Sey mice, along with local retinal damage and a possible neuroinflammatory response.

Summary: The sodium iodate (NaIO3) model is a valuable tool in studying dry AMD and evaluating the retinal structure. Through extensive research, it has been found that the death of RPE cells caused by NaIO3 injection is closely related to vision loss in patients with dry AMD. Therefore, studying NaIO3 can provide insights into the mechanisms of RPE and photoreceptor cell death and contribute to understanding RPE degeneration in AMD.

Summary: We present a new experimental model for inducing retinal ganglion cell (RGC) dysfunction and degeneration in mice. This model allows for the reliable induction of RGC dysfunction and loss, with the resilience of the optic nerve being dependent on the age of the animal. The time-defined nature of the functional and structural changes observed in this model will facilitate the study of glial responses and the evaluation of neuroprotective treatments after intraocular pressure (IOP) injury.
