The Golgi body, a core organelle in eukaryotic cells, plays a critical role in protein modification, sorting, vesicular transport, and serves as a key site for lipid synthesis and glycosylation. Glucose and lipid metabolism are central processes for cellular energy maintenance and biosynthesis, and are closely linked to Golgi function. Recent studies have revealed the extensive involvement of the Golgi body in regulating glucose and lipid metabolism, where maintaining its structural and functional homeostasis is crucial for normal physiological activity. Under various stress conditions such as acidosis, hypoxia, and nutrient deficiency, the Golgi body undergoes structural and functional disruption, leading to Golgi stress. This in turn activates specific signaling pathways, such as those mediated by the cAMP-responsive element binding protein 3 (CREB3) and proteoglycans, to alleviate Golgi stress and enhance Golgi function. Golgi stress contributes to glucose and lipid metabolic disorders by affecting the activity of insulin receptors, glucose transporters, and lipid metabolism-related enzymes. For example, Golgi stress triggers the cleavage and release of the active fragment of CREB3, which enters the nucleus and upregulates the transcription of ADP-ribosylation factor 4 (ARF4) and key gluconeogenic enzymes, including phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase). ARF4 promotes vesicle retrograde transport between the Golgi and endoplasmic reticulum, maintains secretory capacity, and enhances hepatic glucose output. This pathway is particularly active under high-fat or lipotoxic stress, leading to fasting hyperglycemia. When damaged Golgi components accumulate beyond a tolerable threshold, the cell initiates an autophagic response, selectively encapsulating the damaged Golgi into autophagosomes, which then fuse with lysosomes to form autolysosomes, leading to Golgiphagy. This process results in the degradation and clearance of damaged Golgi, thereby regulating Golgi quantity, quality, and function. Golgiphagy also plays a significant role in regulating glucose and lipid metabolism. For instance, under high-glucose conditions, autophagic flux may be suppressed, impairing the timely clearance and renewal of damaged Golgi, compromising its normal function, and further exacerbating glucose metabolism disorders. Additionally, Golgiphagy may participate in lipid degradation and influence lipid synthesis and transport. Research indicates that Golgi stress and Golgiphagy play important roles in glucose and lipid metabolism-related diseases. For example, the leucine zipper protein (LZIP) under Golgi stress conditions can promote hepatic steatosis. In mouse primary cells and human tissues, LZIP induces the expression of apolipoprotein A-IV (APOA4), which increases peripheral free fatty acid uptake, resulting in lipid accumulation in the liver and contributing to the development of fatty liver disease. This review systematically outlines the structure and function of the Golgi apparatus, the molecular regulatory mechanisms of Golgi stress and Golgiphagy, and their synergistic roles. It further elaborates on how Golgi stress and Golgiphagy participate in the regulation of glucose and lipid metabolism, discusses their clinical significance in related diseases such as diabetes, fatty liver disease, and obesity, and highlights potential novel therapeutic strategies from the perspective of Golgi-targeted medicine

OBJECTIVE:
Poxviruses are zoonotic pathogens that infect humans, mammals, vertebrates, and arthropods. However, the specific role of ticks in transmission and evolution of these viruses remains unclear.
METHODS:
Transcriptomic and metatranscriptomic raw data from 329 sampling pools of seven tick species across five continents were mined to assess the diversity and abundance of poxviruses. Chordopoxviral sequences were assembled and subjected to phylogenetic analysis to trace the origins of the unblasted fragments within these sequences.
RESULTS:
Fifty-eight poxvirus species, representing two subfamilies and 20 genera, were identified, with 212 poxviral sequences assembled. A substantial proportion of AT-rich fragments were detected in the assembled poxviral genomes. These genomic sequences contained fragments originating from rodents, archaea, and arthropods.
CONCLUSION
Our findings indicate that ticks play a significant role in the transmission and evolution of poxviruses. These viruses demonstrate the capacity to modulate virulence and adaptability through horizontal gene transfer, gene recombination, and gene mutations, thereby promoting co-existence and co-evolution with their hosts. This study advances understanding of the ecological dynamics of poxvirus transmission and evolution and highlights the potential role of ticks as vectors and vessels in these processes.

Objective:To investigate the preoperative risk features of skip metastasis in medullary thyroid carcinoma(MTC),and analyze the rule and the causes of missed diagnosis of skip metastasis.Methods:A retrospective study of 208 MTC patients in Tianjin Medical University Cancer Institute and Hospital between January 2013 and January 2023 were enrolled. Based on postoperative pathology,patients were classified into without lateral cervical metastasis group( n=102),skip metastasis group( n=21),and non-skip metastasis group( n=85). Prognostic outcomes were compared via Kaplan-Meier analysis in the 3 groups. Univariate and multivariate Logistic regression identified risk factors for lateral cervical metastasis and skip metastasis.The distribution patterns,clinical and sonographic features of metastatic lymph nodes were analysed. Results:Prognostic differences:The group without lateral cervical metastasis showed the highest biochemical cure rate,followed by the skip subgroupand non-skip subgroup( P<0.001). The results of the regression analysis showed male( OR=2.930,95% CI=1.295-6.628),preoperative calcitonin >317 ng/L( OR=9.820,95% CI=3.541-27.234),tumor contact with the length/perimeter ≥1/4( OR=3.275,95% CI=1.353-7.927),a taller-than-wide shape <1( OR=24.239,95% CI=6.319-92.983),irregular margins( OR=3.658,95% CI=1.213-11.036),solid composition( OR=25.639,95% CI=2.295-286.408)and calcifications( OR=15.429,95% CI=4.090-58.202)were independent risk factors for lateral cervicalasis. Tumor size ≤ 1 cm( OR=4.735,95% CI=0.067-0.868)and upper pole involvement( OR=6.879,95% CI=0.069-0.679)were independent risk factors for skip metastasis. The rules of skip metastasis:Skip metastasis group could distribute to levels Ⅱ( n=9),Ⅲ( n=13),Ⅳ( n=14),and Ⅴ( n=2),the number of metastatic lymph nodes was significantly less than non-skipping group[4(8.0) vs.11(17.5), P<0.001]. There were no statistically significant differences in size,shape,hilum,calcifications,peripheral vascularity and the number of high suspicious ultrasound features of metastatic lymph node between the two groups(all P>0.05). Conclusions:The prognosis is best in the without lateral cervical metastasis,followed by skip metastasis,and is worst for non-skip metastasis. A small number of metastatic lymph nodes may be the reason for the missed diagnosis of skip metastasis by ultrasound. Male,calcitonin > 317 ng/L,tumor contact with the length/perimeter ≥ 1/4,a taller-than-wide shape,irregular margins,solid composition and calcifications are independent risk factors for lateral cervicalasis . Tumor size ≤ 1 cm and upper pole involvement should alert to skip metastasis.

Aim To elucidate the mechanism of ma-trine(MT)-induced liver damage.Methods After ex-posure of L02 cells and BALB/c mice to MT,mouse hepatic function,histopathological examinations of the liver,cell viability of L02 cells,reactive oxygen spe-cies(ROS)levels,mitochondrial function,apoptosis,and cystathionine β-synthase(CBS)/H2S/ATP syn-thase F1 subunit alpha(ATP5 A)pathway activity were detected.Results MT treatment decreased L02 cell viabilities in a dose-dependent manner.MT also decreased the levels of CBS and ATP5A S-sulfhydra-tion,increased ROS levels,depolarized the mitochon-drial membrane potential,decreased the biosynthesis of H2S and ATP,ultimately activated the caspase-3 activ-ity and apoptosis(P<0.05).In vivo experiments showed that MT induced severe liver injury in BALB/c mice,along with a decline in CBS,SH-ATP5A,H2S,and ATP levels,and caspase-3 activation(P<0.05).However,either NaHS treatment or methionine treat-ment reversed MT-induced apoptosis and hepatotoxicity by increasing the intracellular H2S levels in vivo and in vitro(P<0.05).Conclusions MT induces ROS ac-cumulation,mitochondrial dysfunction,caspase-3 acti-vation and apoptosis by inhibiting the CBS/H2S/ATP5A pathway.The upregulation of intracellular H2S levels partially reverses MT-induced hepatotoxicity via ATP5A S-sulfhydration.
