Summary: The study revealed that synthetic peptides derived from YPB and OPB domains disrupted the interaction between YY1 and EZH2, inhibiting the proliferation of breast cancer cells and reducing tumor growth. Additionally, these peptides interfered with H3K27 trimethylation and primarily targeted the PTENP1 gene, highlighting its importance in the anticancer activity of YPB and OPB peptides.

Summary: Natural cannabinoids have been used for medicinal purposes by humans for thousands of years, with their anti-inflammatory effects well-documented. The pharmacological effects of cannabinoids are mediated through modulation of CB1 and CB2 receptors, while miRNA expression plays a key role in the immune system's response to cannabinoids.

Summary: A two-tier approach was proposed for targeted combination therapy against metastatic breast cancer. It involves the development of a paclitaxel-loaded micellar system and the chemical anchoring of hyaluronic acid to achieve CD44 receptor mediated targeting. The combination of paclitaxel and betulinic acid showed significant synergy. The integrated system exhibited preferential CD44-mediated uptake and rapid release of drugs in response to higher glutathione concentrations. In vivo administration of targeted micelles resulted in improved pharmacokinetic parameters and significant tumor growth inhibition in mice.

Summary: In patients with Late-onset hypogonadism (LOH) and castrated mice, supplementation of testosterone led to upregulation of miR-125a-5p in plasma, which was positively associated with testosterone concentrations. Further analysis revealed LYPLA1 as a target gene of miR-125a-5p, and testosterone deficiency resulted in decreased global protein palmitoylation level. Our findings suggest that testosterone may regulate global palmitoylation level through the miR-125a-5p/LYPLA1 signaling pathway in LOH, potentially contributing to the molecular mechanism underlying LOH symptoms.

Summary: This study reveals the cardioprotective role of circ_0002612 against myocardial ischemia/reperfusion injury (MI/RI), and identifies its mechanistic actions. circ_0002612 competitively binds to miR-30a-5p to release the expression of its target gene Ppargc1a, promoting cardiomyocyte viability and suppressing apoptosis. Furthermore, circ_0002612 inhibits the expression of NLRP3, leading to enhanced cardiomyocyte proliferation and reduced apoptosis.

Summary: The water-extracted roots of Sanguisorba officinalis L. were found to reduce lactate dehydrogenase A (LDHA) activity and improve physical performance by enhancing AMPKα and PGC-1α levels, while suppressing glycolysis. This suggests that S. officinalis may be a candidate for enhancing physical performance through inhibiting LDHA and glycolysis.

Summary: This study found that the phenolic extract of beluga lentil (BLE) has protective effects against oxidative stress-induced hepatotoxicity. BLE can reduce intracellular reactive oxygen species (ROS) levels and enhance the expression of antioxidant genes. In animal experiments, pretreatment with BLE also significantly reduced liver injury markers and increased the activity of intracellular antioxidant enzymes. Therefore, BLE may be a potential source of nutraceuticals with hepatoprotective effects.

Summary: This study found that alantolactone (ALA) and Inula helenium (elecampane) root extract (IHE) simultaneously target AMPK alpha and Nur77, inhibiting adipogenic differentiation and reducing the expression of adipocyte markers. Further mechanistic studies revealed that IHE shares similar mechanisms of action with isoalantolactone (ISO), reducing mitotic clonal expansion during early adipogenic differentiation and decreasing expression of cell cycle regulators. These results suggest that IHE inhibits adipogenesis through co-regulation of AMPK alpha and Nur77, and may serve as a therapeutic option for obesity and related metabolic dysfunction.

Summary: Buprenorphine is the preferred treatment for opioid use disorder in pregnant women but can cause neonatal opioid withdrawal syndrome (NOWS). The metabolite Norbuprenorphine plays a key role in BUP-associated NOWS and has a greater impact on females. Therefore, reducing prenatal exposure to Norbuprenorphine may be more effective for females than males.

Summary: In this study, it was found that Protaetia brevitarsis larvae (PBL) protein hydrolysates, which have strong antioxidant activity, may protect liver cells from oxidative stress-induced injury. Among the hydrolysates prepared by different proteases, the PBL flavouryzme hydrolysate showed the highest protective effect against H2O2-induced cytotoxicity in liver cells. Mechanistic studies revealed that the protective effect of PFH was associated with its ability to reduce reactive oxygen species and induce antioxidant enzymes.

Summary: An active metabolite of buprenorphine called norbuprenorphine is implicated in neonatal opioid withdrawal syndrome when buprenorphine is taken during pregnancy. This study reports the synthesis and testing of deuterated buprenorphine (BUP-D2), which retains key pharmacodynamic properties of buprenorphine and resists metabolism to norbuprenorphine, making it a potential alternative to buprenorphine.

Summary: Ulcerative colitis is characterized by inflammation in the colon, and obesity is closely related to its occurrence and progression. The connection between obesity and colitis is primarily through excessive adipogenesis-related inflammatory responses that cause mucosal dysfunction. Several etiological mechanisms, including excessive adipogenesis, lipotoxicity, pro-inflammatory adipokines/cytokines, macrophage polarization, oxidative stress, endoplasmic reticulum stress, and gut microbiota, link obesity and colitis. The resulting low-grade enteric inflammations lead to mucosal layer damage, especially goblet cell dysfunction, ultimately resulting in colitis. Inhibiting the inflammatory response is the most effective approach for treating obesity-related colitis.
