Aberrant glycosylation is close involvement in osteosarcoma. Accordingly, this study aimed at investigating the role of glycosylation genes in the prognosis and therapy options of osteosarcoma. The microenvironment of osteosarcoma was assessed using estimate algorithm. A total of 20 immune-related glycosylation genes (IRGGs) was identified using Pearson correlation analysis. Accordingly, osteosarcoma patients were divided into C1 and C2 type using consensus clustering. Multiple algorithms (Xcell, MCP-counter, ssGSEA, epic, quantiseq), cancer immune cycle analysis, and GSVA were applied to estimate the immune, molecule and metabolism characteristics of osteosarcoma, indicating that C1 type was featured with high immune infiltration, high glycosylation, enriched MEK signaling, and good prognosis, while C2 type was characterized by more metastasis, enriched immunotherapy-positive gene signatures, high tumor mutation burden, and poor prognosis. Results from TIDE algorithm and immunotherapy datasets suggested the C2 type’s preference of immune checkpoint inhibitors (ICIs), while data of GDSC, CMap analysis and cell experiments indicated that C1 type was sensitivity to MEK inhibitor PD0325901. In addition, univariate Cox and Lasso analysis was combined to establish an IRGGs’ risk score containing 6 genes (B3GNT8, FUT7, GAL3ST4, GALNT14, HS3ST2, and MFNG). The data of DCA and ROC indicated its well prediction of prognosis in osteosarcoma. Finally, cellular location analysis showed that the 6 genes not only distributed in tumor cells but also in immune cells.

This study investigated the role of <em>GmMLP34</em>, a member of the major latex protein (MLP) family, in the response of soybeans to HT stress. Transcriptome analysis of HT-resistant (JD21) and HT-sensitive (HD14) soybean leaves under HT stress (43.40 ± 1.70 °C) and field conditions revealed differential expression of <em>GmMLP34</em>. Further examination across different HT-resistant varieties showed that <em>GmMLP34</em> was down-regulated in the leaves of 6 HT-resistant varieties (85.7 %) and up-regulated in the leaves of 6 HT-sensitive varieties (85.7 %) under the HT treatment (45 °C for 3 h). The results of this study indicate that ectopic expression of the <em>GmMLP34</em> gene in Arabidopsis led to a significant decrease in the survival rate of seedling when compared to the wild type (WT) under HT stress conditions of 37/28 °C (day/night) for 5 d, Moreover, the results indicated a significant decrease in primary root length and lateral root number under 45 °C/3 h HT stress followed by 12 h room temperature recovery.
