Background: Several cancers show increased levels of lactate dehydrogenase A (LDHA), which are associated with cancer progression. However, it remains unclear whether LDHA levels are associated with papillary thyroid cancer (PTC) aggressiveness or with the presence of the PTC prognostic marker, the BRAFV600E mutation. This study aimed to evaluate the potential of LDHA as a PTC prognostic marker.
Methods: LDHA expression was examined in 83 PTC tissue specimens by immunohistochemistry. Human thyroid cell lines were genetically manipulated to overexpress BRAFV600E or were treated with a BRAF-specific short hairpin RNA (shBRAF), whose effects on LDHA expression were evaluated by Western blotting. Data from 465 PTC patients were obtained from The Cancer Genome Atlas (TCGA) database and analyzed to validate the in vitro results.
Results: LDHA was aberrantly overexpressed in PTC. Intense immunostaining for LDHA was observed in PTC specimens carrying mutated BRAF, whereas the intensity was less in wild-type BRAF samples. Overexpression of BRAFV600E resulted in LDHA upregulation, whereas treatment with shBRAF downregulated LDHA in human thyroid cell lines. Furthermore, LDHA mRNA expression was significantly elevated and associated with BRAFV600E expression in thyroid cancer tissues from TCGA database. Additionally, LDHA overexpression was found to be correlated with aggressive clinical features of PTC, such as lymph node metastases and advanced tumor stages.
Conclusion: LDHA overexpression is associated with the BRAFV600E mutation and an aggressive PTC behavior. Therefore, LDHA may serve as a biomarker and therapeutic target in PTC.

Introduction: The acidic microenvironment caused by excessive lactate accumulation could inhibit immune lymphocytes antitumor activity and promote the immune escape of tumor cells. Baicalin is an active flavonoid isolated from Scutellaria baicalensis Georgi, a traditional Chinese medicinal herb with antioxidant and anti-inflammatory properties.
Objectives: The present study aims to investigate whether and how baicalin inhibits oral squamous cell carcinoma (OSCC) acidic microenvironment and attenuates immune escape.

Invasiveness of pituitary adenoma is the main cause of its poor prognosis, mechanism of which remains largely unknown. In this study, the differential proteins between invasive and non-invasive pituitary tumors (IPA and NIPA) were identified by TMT labeled quantitative proteomics. The differential metabolites in venous bloods from patients with IPA and NIPA were analyzed by untargeted metabolomics.

Article Synopsis
- Acute liver failure (ALF) is a severe condition with high mortality rates, prompting this study to explore the effects of Sini Decoction plus Ginseng Soup (SNRS) on liver health and immune response.
- Using bioinformatics and network pharmacology, the research identified key glycolysis-related genes influencing macrophage polarization and found that SNRS can improve liver injury outcomes and survival rates in an ALF model.
- The study concluded that SNRS may effectively treat ALF by altering macrophage behavior and glucose metabolism through the mTOR/HIF-1α pathway, revealing its potential as a therapeutic option.

Background: Ferroptosis was involved in the pathogenesis of intervertebral disc degeneration (IVDD). However, the exact mechanism of IVDD associated with ferroptosis still required deeper studies.
Method: The differentially expressed genes (DEGs) in rat lumbar disc tissue between the control and IVDD group treated with IL-1β were detected by RNA sequencing (RNA-seq).

Angiogenesis is a significant character of lung adenocarcinoma (LUAD) and is an important reason leading to high mortality rates of LUAD patients. However, the molecular mechanisms of lncRNAs regulating the angiogenesis in LUAD have not been fully elucidated. Here we show lncRNA chromatin-associated RNA 10 (CAR10) was upregulated in the tumor tissue of patients with LUAD and enhanced tumor metastasis.
