The Paired box gene 1 (Pax1) transcription factor plays essential roles in the development of axial skeleton, scapula, pelvic girdle, and thymus. Delineating its pleiotropic and molecular roles in the various tissues requires the ability to track and isolate the Pax1-expressing cells for downstream high-throughput experiments such as microarray and RNA-sequencing. With these applications in mind, we have generated two new mouse lines-a Pax1 wildtype (WT) mouse line that co-expresses enhanced green fluorescent protein (EGFP) with functional Pax1, and a Pax1 knockout mouse line which expresses EGFP under the control of Pax1 promoter, using the internal ribosome entry site (IRES) and 2A-peptide multi-cistron concatenating strategies. These mouse lines facilitate the isolation and enrichment of Pax1-specific cells from Pax1-positive and Pax1-null embryos using fluorescence activated cell sorting (FACS). They can be also be used in parallel to investigate the stage- and tissue-specific molecular functions of Pax1.

Background: Litter size in mice is an important fitness and economic feature that is controlled by several genes and influenced by non-genetic factors too. High positive selection pressure in each generation for Litter size at birth (LSB), resulted in the development of high and low prolific lines of inbred Swiss albino mice (SAM). Despite uniform management conditions, these lines showed variability in LSB across the generation.

Purpose: This study aimed to investigate the role of SIRT4 in retinal protection, specifically its ability to mitigate excitotoxic damage to Müller glial cells through the regulation of mitochondrial dynamics and glutamate transporters (GLASTs).
Methods: A model of retinal excitatory neurotoxicity was established in mice. Proteins related to mitochondrial dynamics, GLAST, and SIRT4 were analyzed on days 0, 1, 3, and 5 following toxic injury.
Temozolomide-Promoted MGMT Transcription Contributes to Chemoresistance by Activating the ERK Signalling Pathway in Malignant Melanoma.

Department of Chemotherapy, Jiangxi Cancer Hospital, Nanchang, Jiangxi, China.
Tumour cells possess a multitude of chemoresistance mechanisms, which could plausibly contribute to the ineffectiveness of chemotherapy. O-methylguanine-DNA methyltransferase (MGMT) is an important effector protein associated with Temozolomide (TMZ) resistance in various tumours. To some extent, the expression level of MGMT determines the sensitivity of cells to TMZ, but the mechanism of its expression regulation has not been fully elucidated.

Introduction: Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumors in oral and maxillofacial region. The development of new chemotherapy agents and new drug combinations may improve patient survival and quality of life, but both surgery and radiotherapy have significant functional side effects and drug resistance, ultimately resulting in a 5-year survival rate of no more than 60% for OSCC patients. Studies have shown that Brucea javanica oil (BJO) extracts have anti-cancer effects against a variety of cancers, but little research has been reported on OSCC.

Introduction: Arjunolic acid, a well-known natural product with various medicinal properties, was isolated from the heartwood of Terminalia arjuna. Various amides of arjunolic acid were synthesized using different aryl and cyclic amines, characterized, and evaluated for their anti-cancer activities at the National Cancer Institute (NCI).
Method: All the derivatives were active against all the cell lines of NCI compared to the parent molecule arjunolic acid.
