Once this line was generated, we backcrossed it for two generations with purebred C57BL/6J mice. All animal procedures followed the protocol (PIL‐16‐01‐002) approved by the Institutional Animal Care and Use Committee of the Van Andel Institute. Mice were housed in climate‐controlled conditions (25 °C, 55% humidity, and 12 h of light alternating with 12 h of darkness) and fed a standard LabDiet Rodent Chow 5010 (Purina Mills, Gray Summit, MO, USA). Animals for our studies were euthanized at embryonic day 13 to collect mouse embryonic fibroblasts (MEFs) or at a 36‐week time point for bone studies.
B6c3f1 j mice
B6C3F1/J mice are a widely used mouse strain that is a hybrid of the C57BL/6J and C3H/HeJ mouse strains. They are commonly used in biomedical research, including studies related to cancer, toxicology, and immunology.

Intracranial Glioma Models and Toca 511/5-FC Therapy
animal care and use committees. Six- to 8-week-old female nude mice (Hsd:Athymic
Nude-Foxn1nu; Envigo) or B6C3F1/J mice (Jackson Laboratory) were bred
and maintained under specific pathogen-free conditions. To establish intracranial gliomas,
U-87 (1 × 105) or Tu-2449 (1 × 104) cells were stereotactically
injected into the right frontal lobe in mice, as described previously.8 (link) In U-87 tumor models, Toca 511 (low dose:
3.4 × 104 transducing units [TU] or high dose: 2 × 106 TU) was given
by stereotactic injection on day 5, and daily intraperitoneal (i.p.) administration of
5-FC (500 mg/kg once daily or twice daily) or phosphate buffered saline (PBS) was started
on day 18 for 7 consecutive days. This 7-day cycle was repeated at intervals of every 1–2
weeks. In Tu-2449 tumor model studies conducted at UCLA, Toca 511 (2 × 106 TU)
was given by stereotactic injection on day 4, and daily i.p. administration of 5-FC or PBS
was started on day 10 for 7 consecutive days. This cycle was repeated at intervals of
every 10 days. In independent Tu-2449 studies conducted at Tocagen, Toca 511 was
administered as above at 3 × 106 TU followed by 4 cycles of 5-FC administered
twice a day for 4 days every 2 weeks, or at a lower dose (1.6 × 104 TU), and
continuous 5-FC administered once a day for 14 or 21 consecutive days.
Topical DBP Exposure in Mice
Mice received topical treatment of DBP (24 nmol, 3 times per week for 5 weeks) in the oral cavity and were euthanized 48 h after the last dose; this time point was selected based on our previous study showing maximum levels of DNA adducts [25 (link)]. Animals treated with dimethyl sulfoxide (DMSO) as the vehicle were used as control. At termination, mice were euthanized by CO2 asphyxiation; oral tissues were isolated from the same anatomic sites of mice treated with vehicle or DBP (soft tissues of the oral cavity, including the buccal mucosa and floor of the mouth as well as soft tissues attached to the hard palate) and pooled together for DNA extraction.

Striatal Injection of α-Synuclein Fibrils
Sonicated PFFs (5 μg total in 2.5 μl of PBS) were stereotaxically injected in the dorsal striatum using the following coordinates: AP +0.2 mm, M/L 2.0 mm and depth beneath skull 2.6 mm. Each mouse received a single unilateral injection of the indicated PFFs. At the post-injection time points indicated, mice were transcardially perfused with heparinized PBS, and brains were removed for fixation in 70% ethanol in 150 mM NaCl, pH 7.4.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
