Downregulation of growth plate genes involved with the onset of femoral head separation in young broilers. Front Physiol 2022; 13:941134.

Abstract
Femoral head separation (FHS) is characterized by the detachment of growth plate (GP) and articular cartilage, occurring in tibia and femur. However, the molecular mechanisms involved with this condition are not completely understood. Therefore, genes and biological processes (BP) involved with FHS were identified in 21-day-old broilers through RNA sequencing of the femoral GP. 13,487 genes were expressed in the chicken femoral head transcriptome of normal and FHS-affected broilers. From those, 34 were differentially expressed (DE; FDR ≤0.05) between groups, where all of them were downregulated in FHS-affected broilers. The main BP were enriched in receptor signaling pathways, ossification, bone mineralization and formation, skeletal morphogenesis, and vascularization. RNA-Seq datasets comparison of normal and FHS-affected broilers with 21, 35 and 42 days of age has shown three shared DE genes (FBN2, C1QTNF8, and XYLT1) in GP among ages. Twelve genes were exclusively DE at 21 days, where 10 have already been characterized (SHISA3, FNDC1, ANGPTL7, LEPR, ENSGALG00000049529, OXTR, ENSGALG00000045154, COL16A1, RASD2, BOC, GDF10, and THSD7B). Twelve SNPs were associated with FHS (p < 0.0001). Out of those, 5 were novel and 7 were existing variants located in 7 genes (RARS, TFPI2, TTI1, MAP4K3, LINK54, and AREL1). We have shown that genes related to chondrogenesis and bone differentiation were downregulated in the GP of FHS-affected young broilers. Therefore, these findings evince that candidate genes pointed out in our study are probably related to the onset of FHS in broilers.

Abstract
Generating phenotypic chondrocytes from pluripotent stem cells is of great interest in the field of cartilage regeneration. In this study, we differentiated human induced pluripotent stem cells into the mesodermal and ectomesodermal lineages to prepare isogenic mesodermal cell-derived chondrocytes (MC-Chs) and neural crest cell-derived chondrocytes (NCC-Chs), respectively, for comparative evaluation. Our results showed that both MC-Chs and NCC-Chs expressed hyaline cartilage-associated markers and were capable of generating hyaline cartilage-like tissue ectopically and at joint defects. Moreover, NCC-Chs revealed closer morphological and transcriptional similarities to native articular chondrocytes than MC-Chs. NCC-Ch implants induced by our growth factor mixture demonstrated increased matrix production and stiffness compared to MC-Ch implants. Our findings address how chondrocytes derived from pluripotent stem cells through mesodermal and ectomesodermal differentiation are different in activities and functions, providing the crucial information that helps make appropriate cell choices for effective regeneration of articular cartilage.

Abstract
Intervertebral disc (IVD) degeneration of is considered to be initiated by the degeneration of the cartilage endplate (CEP). CEP‑derived stem cells (CESCs) with the capacity for osteochondrogenic differentiation may be responsible for CEP cartilage restoration. As CEP is avascular and hypoxic, and hypoxia can greatly influence biological activities of stem cells, physiological hypoxia may serve important roles in regulating the physiological functions of CESCs. The aim of the present study was to investigate the mechanisms of hypoxia‑regulated CESCs fate by using the Human Transcriptome Array 2.0 system to identify differentially expressed genes (DEGs) and alternatively spliced genes (ASGs) in CESCs cultured under hypoxic and normoxic conditions. The high‑throughput analysis of both DEGs and ASGs were notably enriched in the immune response signal, which so far has not been investigated in IVD cells, due to their avascular nature and low immunogenicity. The present results provided a referential study direction of the mechanisms of hypoxia‑regulated CESC fate at the level of gene expression and alternative splicing, which may aid in our understanding of the processes of CEP degeneration.

Abstract
Tubulin tyrosine ligase like 12 (TTLL12), a member of the tubulin tyrosine ligase (TTLL) family, has not been completely characterized to date. It is reported that histone methylation, tubulin modifications, mitotic duration and chromosome ploidy play crucial roles in a variety of cancers, and are related to tumorigenesis and cancer progression. A recent study showed that TTLL12 may be a pseudo-enzyme which has a SET-like domain and a TTL-like domain. In the present study, we first used 3′-rapid amplification of cDNA ends (3′-RACE) to amplify the transcripts of the TTLL12 gene from a human lung cancer cell line H1299, and unexpectedly discovered a new transcript isoform characterized with an additional 108-bp nucleotide sequence inserted at the location from 902 to 903 bases of the TTLL12 coding sequence (CDS), where it also locates between exons 5 and 6. Next, utilizing RT-PCR and Sanger sequencing, we further confirmed the existence of such a new transcript isoform of TTLL12 in more human cancer cells including lung cancer cells and other cancer cells. Moreover, several lung cancer cell lines were found to display a much higher proportion of the new isoform compared with TTLL12 wild-type transcript. These results suggest that the new TTLL12 isoform may be of importance for proper maintenance of lung cancer cells. Therefore, the new isoform of TTLL12, with the inserted sequences probably acting as a disordered region, provides a novel perspective regarding TTLL12 functions in human cancers including lung cancer.
